Downtown Los Angeles (USC) ended the 2020-21 rain year (July 1 to June 30) with 5.82 inches of rain. This is about 41% of the new normal annual precipitation total of 14.25 inches. Much of the West recorded below average precipitation for the rain year.

The amount of rainfall that is considered "normal" for Downtown Los Angeles has decreased nearly an inch in the past three decades. The normal rainfall for Los Angeles was 15.14 inches based on 1971-2000 climate data, and dropped to 14.93 inches based on data from1981-2010. Analysis of 1991-2020 data provided the new normal of 14.25 inches. Interim 2006-2020 climate data is shockingly dry, with normal rainfall in Los Angeles calculated at only 11.39 inches! For more info see U.S. Climate Normals and Normals Calculation Methodology 2020 (PDF).

La Nina conditions developed in August 2020 and transitioned to ENSO-neutral in April 2021. The Oceanic Nino Index (ONI) decreased to a minimum of -1.3 in the Oct-Nov-Dec season. The EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION issued August 12, 2021 projects a 70% chance of La Nina conditions being present during November-January.

Los Angeles rainfall during La Ninas has been variable, but skewed to the drier side. The average rain year precipitation for the 24 ERSST.v5 ONI-based Cold Episodes since 1949 is 11.84 inches. The highest amount was 20.20 inches in 2010-11 and the lowest 4.68 inches in 2017-18. In the past decade, rainfall totals for Los Angeles have been less in the second year of successive cold episodes, but this pattern doesn't hold up over the entire record.

As of today Downtown Los Angeles (USC) December rainfall is 1.75 inches above the monthly normal of 2.33 inches. Not since the beginning of the drought has Los Angeles experienced such a wet December. The 4.08 inches of rain recorded so far this month is the most since December 2010 and the most for any month since January 2010.

Since the Rain Year began July 1, 5.48 inches of rain has fallen at Downtown Los Angeles (USC). This is more than an inch above the normal July-December rainfall of 4.32 inches. It is the best start to the Rain Year (Jul 1-Jun 30) and Water Year (Oct 1-Sep 30) since 2010.

While the rain is good news, this graphic from the Western Regional Climate Center shows that the Jul-Dec precipitation in some areas of Southern California is still below normal.

Forecasting how the cut off upper level low currently spinning offshore southwest of Los Angeles and a developing upstream trough interact is a tough task, even for a supercomputer. The trough is expected to propel the low in our general direction and then replace/absorb it. Add to the mix the possibility of pulling up some sub-tropical moisture (or not) and the forecast becomes even trickier. Guess we'll see!

Downtown Los Angeles (USC) finished the 2015-16 rainfall year (July 1 to June 30) with 9.65 inches of recorded precipitation. This is about 65% of the 1981-2010 normal of 14.93 inches. This was the fifth consecutive year of below normal rainfall for Downtown Los Angeles, with a cumulative rainfall deficit of 35.86 inches --nearly three feet!

Observable impacts of the drought are widespread. Trees have been particularly hard hit. Dead trees can be seen along city streets, in parks, and throughout the open space areas and wildlands of Southern California. The dead and dying 100+ year old coast redwoods at Malibu Creek State Park are an example.

Most climate outlooks are forecasting La Nina conditions to develop over the Northern Hemisphere summer. Historically La Ninas have "on average" resulted in below normal precipitation in Southern California. But historical composites can be misleading. During the last five La Nina episodes (1999-00, 2000-01, 2007-08, 2010-11, 2011-12) Downtown Los Angeles (USC) has averaged 14.39 inches of rain, which is 96% of normal.

Even during one of three strongest El Ninos on record, precipitation outlooks based on historical composites and analogs didn't perform well in Southern California. Given the somewhat more variable rainfall in Southern California during La Ninas, to determine the winter precipitation outlook you might as well flip a three-sided coin.

After being negative for 3 1/2 years, the PDO Index has been positive since January 2014. December's PDO value of 2.51 is the highest for that month on record (since 1900), exceeding December 2002's value of 2.10 and December 1940's value of 1.96.

Even so, the highly anticipated 2014-15 El Nino continues to dawdle with little ocean-atmosphere coupling and an emphasis on an higher amplitude meridional flows. Due in part to the upwelling phase of a series of oceanic Kelvin waves, equatorial Pacific heat content and SST anomalies have diminished. After having been at or above 0.5 °C for the past twelve weeks OISST.v2 Nino 3.4 SST Anomalies dropped to 0.4 °C for the week centered on January 7, 2015 and as of the week of January 14 was at 0.5 °C.

The Multivariate ENSO Index (MEI) for NOV/DEC has decreased 0.13 SD to +0.58, but has maintained its historic rank (since 1950) at 47. A rank of 46 is the threshold for weak El Nino conditions in the context of the MEI. The FNL Global Wind Oscillation for the past 90 days continues to reflect the lack of definitive atmospheric coupling.

So far this rain season Northern California and the coastal areas of Central and Southern California have fared much better in terms of precipitation than last year. As of today Downtown Los Angeles (USC) precipitation for the water year (beginning July 1) is at 90% of normal and Downtown San Francisco is at 127%.

As this AHPS plot of precipitation since October 1 shows, many areas of California have recorded at least 75% of normal precipitation. Unfortunately the Sierra Nevada is not one of them. While better than last year's dismal 14% of normal on this date, this year's snowpack is currently well below average, and was last reported at 36%. Here is an AHPS plot of precipitation departure since October 1 that shows the deficits in the Sierra Nevada.

At the moment it doesn't look like the snowpack will get much help in the short term. After fending off a little shortwave the blocking ridge is forecast to rebuild to new heights, bringing unseasonably mild weather to much of the West Coast. There does appear to be the possibility of a wildcard low latitude low developing under the block and that could result in some precipitation in Southern California next week. If such a system develops, given the warm state of the Eastern Pacific, it could be wetter than expected. We'll see!

In the early morning hours of Friday, December 12, 2014, a very strong cold front, enhanced with moisture from an atmospheric river, produced a line of strong storms that produced rain rates in the Springs Fire burn area as high as 2 inches per hour. This resulted in widespread flash floods and debris flows in the burn area, much of which is in Pt. Mugu State Park. Mud and debris flows originating from the burn area inundated homes below Conejo Mountain and closed Pacific Coast Highway. This slideshow includes photos of the aftermath of the flash floods and debris flows in Blue Canyon, Sycamore Canyon and Upper Sycamore. The photos were taken on a trail run on December 14, 2014. Also included are some NWS Los Angeles/Oxnard tweets and some additional meteorological images and info.

After being negative for 3 1/2 years, the PDO Index has been positive since January 2014. October's PDO value of 1.49 is the 6th highest for that month since 1900 and comparable to PDO Index values in October 1997, 1957, 1993, and 1987.

PDO/AMO-based Precipitation composites suggest a warm Pacific generally produces more Winter precipitation in California than a cold Pacific. This makes sense. Among other effects a warm Pacific increases evaporation, air temperature, and the amount of water vapor transferred to the atmosphere. This in turn can increase precipitation. Here is a comparison of Pacific SST anomalies at the beginning of December 2014 and December 2013. Mouse over the image to switch to the December 1, 2013 image.

A warm Pacific may have contributed to the amount of precipitation produced in California by a large Pacific upper level low this past week. Two periods of rain were observed in Southern California -- one on Sunday and the other on Tuesday and Wednesday.

Sunday an embedded short wave in the moist southerly flow produced more rain than expected in many areas of Los Angeles. Surprisingly high rain rates and amounts in the Santa Monica Mountains, resulted in debris flows in the Springs Fire burn area that closed PCH. Here's a NWS compilation of some rainfall totals in the forecast area.

Even with the parent low lifting to the north on Tuesday and the 570 mb contour near Santa Barbara, the very moist southerly flow orographic lift and sufficient dynamics produced widespread precipitation in Southern California with some impressive precipitation totals. Tuesday record rainfall for the date occurred at both Downtown Los Angeles and Downtown San Francisco. Yucaipa Ridge in the San Bernardino Mountains recorded a whopping three-day rainfall total of 14.6 inches. Following are three-day rainfall compilations from the NWS Los Angeles/Oxnard and NWS San Diego.

Here are graphics from the CNRFC with gridded precipitation totals for the four day period from early Sunday morning to early Thursday morning for Southern California, the Sierra Nevada and the San Francisco Bay Area. Some preliminary precipitation totals of 5 inches or more are noted.

Equatorial Pacific SSTs continue to rebound with OISST.v2 Nino 3.4 SST Anomalies above 0.5 °C for the past seven weeks and now stand at 1.0 °C for the week centered on November 26, 2014. The Multivariate ENSO Index (MEI) for OCT/NOV has increased 0.35 SD to 0.71, increasing its historic rank (since 1950) from 42 to 47, just within the MEI's weak El Nino threshold. However as noted by the CPC in their December 4, 2014 ENSO Diagnostic Discussion, "the overall atmospheric circulation has yet to show a clear coupling to the anomalously warm waters." The FNL Global Wind Oscillation for the past 90 days continues to reflect the lack of definitive atmospheric coupling

For now the Pacific storm door appears to be open. Most medium-range guidance is suggesting another significant system will be affecting California in the Thursday-Friday timeframe. We'll see!

One thing is very clear; we have a lot to learn about the atmosphere's response to anomalously warm equatorial Pacific SSTs. It's difficult to imagine a better scenario for El Niño development than the conditions seen in the equatorial Pacific earlier this year.

After being negative for 42 out of the previous 43 months, the Pacific Decadal Oscillation (PDO) index turned positive in January 2014 and has remained positive through the summer. Beginning in January and ending in late June the downwelling phase of a very strong Kelvin wave propagated across the Pacific, with upper ocean area-averaged heat content anomaly between 180 and 100W peaking at the end of March. Since January there have been westerly wind bursts and periods of increased low-level westerly zonal wind anomalies of variable duration and extent.

The Oceanic Niño Index (ONI) jumped from -0.5 in the FMA season to -0.1 in MAM, and then to +0.1 in AMJ. During that same period the Multivariate ENSO Index (MEI) jumped from a rank of 35 in MARAPR to 59 in APRMAY -- a value that put it on the doorstep of a strong El Nino ranking. Which all looked supportive of at least a moderate El Nino developing.

But it didn't. After climbing up to 0.6 °C in late May, Nino 3.4 region SST anomalies dropped to below 0.0 °C in late July. Since then a more modest downwelling Kelvin wave has restored some of the basin heat content and Nino 3.4 anomalies have rebounded back to 0.6 °C.

So what's next? While El Nino development still appears to be possible this Winter, it would be one of the two latest developing El Ninos in the record from 1950 to the present -- the other being 1952-53. One possibility is that this year's vacillations are the precursor to the EARLY development of an El Nino event next year.

One worrisome detail is that the Global Wind Oscillation (GWO) has been behaving similarly to the failed El Nino of 2012. Compare this plot of the GWO from June 1 to October 31 of this year to the plot of the GWO from June 1 to October 31, 2012. In both 2014 and 2012 the GWO has shown a neutral or weak La Nina-like response. The GWO for the period June 1 to October 31, 1997 is an example of a definitive atmospheric response to strong El Nino conditions.

On a more positive note, a relatively strong, but fast-moving Pacific cold front and trough resulted in rain and snow in California over Halloween. In the Los Angeles area rainfall amounts generally varied from around 0.3 inch to 0.75 inch or so with isolated amounts as high as about 2.0 inches in the mountains. Here are some tabulated rainfall amounts from around the area from the NWS Los Angeles/Oxnard and NWS San Diego.

The 1981-2010 climate normal average rainfall for Downtown Los Angeles in November is 1.04 inches. Month to date we're about average for the date, and water year to date we're ahead of last year, but about 0.6 inch below normal.

Based on the current GFS and ECMWF forecasts those deficits are probably going to increase over the next two weeks, but it is way too early in the rain season to attribute the dry weather to a continued dry pattern. El Niño or not; dry November or not; the switch from a cold Pacific to a warm Pacific is a significant change and one that some guidance suggests should increase our rainfall. We'll see!

The "PDO minus AMO" composite precipitation anomaly maps prepared by Dr. Klaus Wolter of CIRES as part of an experimental seasonal forecast for the California DWR last year were consistent with the below average precipitation observed in California in the water years Oct 2012 - Sep 2013 and Oct 2013 - Sep 2014.

As referenced in Dr. Wolter's 2013 DWR presentation, Schubert et al. (J. Climate, 2009) found that five global climate models produced the least precipitation in the continental U.S. when the Pacific is cold (Pc) and the Atlantic warm (Aw). Conversely four of the five models produced the wettest conditions when the Pacific is warm (Pw) and Atlantic cold (Ac). As shown in this figure, all combinations with the Pacific cold (PcAw, PcAn, PcAc) produced below average precipitation and all combinations with the Pacific warm (PwAw, PwAn, PwAc) produced above average precipitation.

While the development of the 2014 El Nino has waxed and waned over the past several months, there has been a definitive change that might significantly impact the weather in California and the U.S. -- the Pacific has warmed. For five of the past six years the JUL-SEP PDO has been negative. This year the PDO has been positive since January.

To get an idea of how the change to a warm Pacific might affect precipitation in the U.S. the PDO index and AMO index values for JUL-SEP for the past 115 years were ranked and then divided into tercile classes, producing nine PDO/AMO states.

The NOAA/NCDC Climate Division Mapping and Analysis Web Tool was then used to generate composite precipitation maps for October to September and December to January for the six combinations of Pacific warm and Pacific cold states: PwAw, PwAn, PwAc and PcAw, PcAn, PcAc.

The PwAw composites show much more precipitation in Southern California and the Southwestern U.S. than the PcAw composites. It might be argued that it is the El Nino years in the PwAw composites that produce the wet signal in Southern California. However, if the El Nino years are removed from the PwAw composites for Oct-Sep and composites for Dec-Feb, a wet signal persists.

Of course there are many factors that can influence the amount of precipitation in a particular locale in a particular season or water year. Composites are not forecasts any more than monthly climate normals are forecasts; but both can provide useful guidance. In the PwAw case 7 of the 12 selected years in the composite were wet in Southern California and two-thirds of the years had near normal or above average precipitation. We'll see what happens in 2014-2015.

Extended by the active phase of the MJO, a strong Pacific jet provided the impetus for two Pacific storm systems to undercut a persistent ridge over the West Coast and bring much-needed rain to parched California.

Beginning Wednesday evening (Feb 26) and continuing into Sunday (Mar 2), the storm systems produced the most rain over five days in Los Angeles since December 2010, ending a nearly 14 month period with record-setting dry weather. Los Angeles experienced the driest calendar year on record in 2013, and until Friday had recorded less water year rainfall than in 2006-07 — the driest water year (July 1 - June 30) since recordkeeping began in 1877.

According to preliminary precipitation data, Downtown Los Angeles (USC) recorded 4.52 inches of rain over the course of the storms, increasing its water year total from a dessicated 11% of normal to a not-too-bad-considering 50% of normal. Downtown Los Angeles' water year rain total now stands at 5.72 inches. This exceeds last year's cumulative precipitation total on this date by more than an inch, but still leaves us with a deficit of nearly six inches. The storms increased February's rainfall total to near normal, and jump-started March with nearly half its normal amount of rain. Prior to these storms the most rain recorded at Los Angeles in a day this water year was 0.29 inch back in November!

Orographically favored foothill and mountain areas that faced into the storms' moist southerly flow recorded some impressive rainfall totals. According to this compilation of preliminary rainfall totals from the NWS Los Angeles/Oxnard, Opids Camp near Mt. Wilson recorded nearly 11 inches of rain, and several stations in the Ventura Mountains recorded double-digit rainfall totals. Here are a CNRFC map of Gridded QPE for the 7-day period ending March 3 at 4:00 am and a CNRFC map of 7-day Gridded QPE and 120 hr raw precipitation for stations recording over 4.0 inches.

With this recent rainfall 2013-14 will not be the driest water year in Los Angeles, but one good storm, or even two, "does not a rain season make." In the short term these storms have dramatically reduced the fire danger, provided crucial relief to plants and animals, and increased groundwater and reservoir storage. What happens in the longer term we'll just have to see. Over the next several days a series of systems are forecast to produce additional rain from Central California north into the PNW. While no rain is forecast in Southern California over the next week or so, and the 8-14 day outlook is for below average precipitation, as long as the Pacific weather pattern remains progressive there should be additional opportunities for rain in the weeks ahead.

It looks like El Nino is beginning to knock more loudly at the door. The third and strongest of a series of oceanic downwelling Kelvin waves continues to significantly increase subsurface equatorial heat content in the Pacific basin and another strong Westerly Wind Burst has occurred in the equatorial Pacific. The CFSv2 forecasts Nino 3.4 anomalies to reach El Nino thresholds in the May-June 2014 timeframe, however the IRI/CPC Plume-based and Consensus Forecasts released February 20 are less bullish, forecasting about a 40% chance of El Nino conditions developing in the MJJ season. We'll see!

Since January 1 Downtown Los Angeles has recorded only 3.60 inches of rain, making it the driest calendar year since recordkeeping began in July of 1877. The previous record of 4.08 inches was set in 1953 and 1947. Downtown Los Angeles averages about 15 inches of rain in a calendar year.

Precipitation composites for years with comparable PD0-AMO indices constructed by Dr. Klaus Wolter of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado appears to have anticipated this year's drought in Southern California. While Oct-Dec anomalies for Southern California were -0.5 to -0.7 SD below the 1895-2000 Longterm Average, Jan-Mar anomalies were -0.1 to -0.3 SD below average. Assuming the anomaly maps to be correlative the drought's stranglehold on Southern California may weaken somewhat over the next three months.

To get an idea of how the precipitation anomaly might vary over the next three months, the US Climate Division Dataset Mapping Page was used to recreate the standardized Oct-Dec precipitation anomaly and Jan-Mar precipitation anomaly maps using the same years as Dr. Wolter's composites. Then standardized composite precipitation anomaly maps were constructed for the months of January, February, and March. Based on these composites some lessening of the severity of the drought in Southern California is suggested throughout the period Jan-Mar with the biggest improvement indicated in March -- except for coastal Southern California. A map showing the composite precipitation anomaly in inches for the period October to March was also generated.

While today's medium range forecasts and 6-10 day and 8-14 day precipitation outlooks aren't particularly encouraging there are some straws to grasp. The AO Index, which has been positive for most of the rainy season is now negative and the Global Wind Oscillation (GWO) is in its first full orbit into positive AAM territory in several months. Whether these changes eventually result in rain for Southern California we'll just have to see.

An experimental PSD forecast issued November 19, 2013 for the period December 2013 through February 2014 prepared for the California DWR by Dr. Klaus Wolter of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado shows a significantly increased chance of less than normal precipitation in most of Southern California and the Central San Joaquin Valley. The forecast guidance shows the shift in tercile probabilities for precipitation, similar in concept to the NOAA CPC precipitation outlooks.

According to Dr. Wolter the statistical forecast scheme integrates as many of the known influences on California's climate as possible, using data from 1950 onwards. In the absence of El Nino and La Nina influences considerations such as the status of the Pacific Decadal Oscillation (PDO), the Atlantic Multidecadal Oscillation (AMO), or recent Alaskan temperatures can be evaluated through statistical models to make a forecast.

Dr. Wolter also produced composite precipitation anomalies for the periods October-December and January-March for years with comparable PD0-AMO indices. In Southern California the Oct-Dec anomalies were -0.5 to -0.7 SD below the 1895-2000 Longterm Average and the Jan-Mar anomalies were -0.1 to -0.3 SD below average.

Since October 1 precipitation in California, Oregon and Washington has generally been well below normal. As of today the precipitation recorded at Downtown Los Angeles is at about 30% of normal for the water year (July 1-June30). If Los Angeles doesn't record more than 0.58 inch of rain over the remainder of December, 2013 will rank as the driest calendar year on record.

A wildcard in the California precipitation outlook is the occurrence of atmospheric rivers such as those that occurred at the end of November 2012 and during December 2010. An analysis of all winter ARs in California during WY1998–2011 presented in the paper The 2010/2011 snow season in California's Sierra Nevada: Role of atmospheric rivers and modes of large-scale variability by Bin Guan, et.al., found that atmospheric river frequency is increased during negative phases of the Arctic Oscillation (AO) and the Pacific-North American (PNA) teleconnection patterns.

Updated November 5, 2013. My mistake -- a spreadsheet range error -- thanks for the heads up Reg! The driest January 1 to November 1 for Downtown Los Angeles was in 1972 with 0.92 inch. Here are the driest ten years for that period:

1. 1972 0.92
2. 2002 1.62
3. 1984 1.93
4. 1961 2.37
5. 1971 2.39
6. 1947 2.45
7. 2013 2.78
8. 1894 2.89
9. 1953 2.89
10. 2007 3.37

An energetic upper level low brought the first widespread precipitation of the rain season to Southern California October 9, with rain at the lower elevations and some snow in the local mountains. Rainfall amounts varied widely, ranging from a trace in some areas to over an inch in the mountains.

Downtown Los Angeles (USC) recorded only 0.04 inch for the storm, bringing the water year rainfall total to 0.13 inch, which is 0.31 inch below normal. Downtown Los Angeles has recorded only 2.76 inches of rain since January 1. This is one of the driest January 1 - October 20 in Los Angeles over the past 135 years! To get out of the bottom ten for calendar year rainfall Los Angeles needs about 3.5 inches of rain by December 31. Normal rainfall for November is 1.04 inches and for December is 2.33 inches.

For months I've been monitoring climate data and forecasts looking for something on which to base a 2013-14 Winter precipitation Outlook. Historically ENSO has played the major role in Southern California rain season weather, with El Nino conditions generally producing wetter weather and La Nina conditions generally drier. But ENSO conditions are currently Neutral and are expected to remain so through the end of the year.

Most climate models forecast slow warming of SSTs in the equatorial Pacific (NINO 3.4 region) over the next several months, but at this time of the year it would be very unusual to have substantial warming. The CPC/IRI ENSO Forecasts from IRI's October Quick Look indicate the probability of an El Nino developing before the end of the year is less than 20% -- and 20% seems high.

One computer model that at times has been forecasting above average precipitation in Southern California this Winter is the Climate Forecast System version 2 (CFSv2). The CFSv2 is fully coupled ocean-atmosphere-land-sea ice model used to forecast parameters such as sea surface temperature, temperature and precipitation rate. While skillful at predicting tropical SSTs, the CFSv2 generally performs very poorly when forecasting precipitation over land, so forecasts such as this earlier one for Dec-Jan-Feb must be viewed somewhat skeptically.

Another glass half-full observation is that the Madden-Julian Oscillation (MJO) has been relatively active this year and if this activity continues it provides recurring opportunities for enhanced U.S. West Coast precipitation. The downside is that it can result in periods of dry weather as well.

With the ocean and atmosphere neutral there's just not much on which to base a rain season forecast. As a result of the government shutdown the release of the official NOAA 2013-14 Winter Outlook has been delayed until November. The October CPC outlook is usually the basis of the initial official NOAA U.S. Winter Outlook. The U.S. Dec-Jan-Feb Precipitation Outlook, released October 17, calls for an equal chance of below average, average, or above average precipitation for all of California. We'll see!

Judging from this NEXRAD regional composite radar image last week's system might have been much wetter. As has happened a couple of times this season, much of the heavier rain appears to have remained offshore. Even so, this compilation of rainfall totals from around the area by the NWS Los Angeles/Oxnard lists some respectable rainfall totals for a late season storm in Southern California.

Downtown Los Angeles (USC) recorded 0.49 inch for the storm, increasing April's rainfall total to 1.71 inches. This is almost double April's normal of 0.91 inches. The water year total rainfall for Downtown Los Angeles now stands at 8.68 inches; which is about 60% of normal at this point in the water year. The water year extends from July 1 to June 30.

In a "normal" season Los Angeles would be expected to record another 0.35 inch of rain by June 30. Both the 6-10 Day Precipitation Outlook and 8-14 Day Precipitation Outlook from the CPC are indicating a better chance of below normal precipitation in Southern California than of normal or above normal precipitation. The CPC Monthly and Three Monthly Temperature and Precipitation Outlooks are indicating an equal chance of above normal, normal, and below normal precipitation in Southern California. We'll see!
