The California Drought monitor is a subset of the United States Monitor, issued every Thursday morning, based on drought conditions the previous Tuesday. The map below shows the current drought level around the state, and the percent of California land area in each drought level compared to the previous week.

WATER SUPPLY OUTLOOK
NATIONAL WEATHER SERVICE SACRAMENTO CA
652 AM PST FRI MAR 7 2014

...BELOW AVERAGE FLOOD POTENTIAL EXPECTED FOR CALIFORNIA THIS 
SPRING...

THE SPRING FLOOD POTENTIAL OUTLOOK IS BELOW AVERAGE FOR ALL BASINS 
IN CALIFORNIA AND THE UPPER KLAMATH LAKE BASIN IN OREGON.  LOW 
SOIL MOISTURE CONDITIONS DUE TO PROLONGED DROUGHT AND/OR BELOW 
NORMAL SNOWPACKS ARE MINIMIZING THE POTENTIAL FOR FLOODING THIS 
SPRING.  WATERSHEDS IN THE REGION ARE FORECAST TO ENDURE A THIRD 
CONSECUTIVE YEAR OF BELOW AVERAGE SPRING RUNOFF.

THE APRIL 1ST AVERAGE SNOWPACK IS MUCH WORSE THAN AT THIS TIME 
LAST YEAR.  BASED ON SNOW SENSOR MEASUREMENTS MAINTAINED BY THE 
CALIFORNIA COOPERATIVE SNOW SURVEYS...THE STATEWIDE PACK STANDS 
AT ABOUT 30 PERCENT OF THE APRIL 1ST AVERAGE AS OF MARCH 6, 2014.  
IT WAS 57 PERCENT AT THIS TIME LAST YEAR.  ALTHOUGH SOME RELIEF 
OCCURRED DURING FEBRUARY AND THE BEGINNING OF MARCH...MOST OF 
THE STATE EXPERIENCED VERY DRY CONDITIONS FROM OCTOBER THROUGH 
JANUARY OF THE CURRENT WATER YEAR (OCTOBER 1, 2013 THROUGH 
FEBRUARY 28, 2014).  IT WILL TAKE A SERIES OF STRONG STORM 
SYSTEMS TO RETURN THE SNOWPACK TO NORMAL CONDITIONS BY APRIL 1ST
...WHICH IS THE TYPICAL TIME OF MAXIMUM SNOWPACK ACCUMULATION.  
IT APPEARS VERY UNLIKELY THAT SNOWPACKS CAN RECOVER FROM THE 
CURRENT DEFICIT THIS LATE INTO THE WET SEASON. NOTE THAT 
FLOODING COULD STILL RESULT FROM HEAVY RAINFALL ALONE OR 
COMBINED WITH SNOWMELT ANYTIME BETWEEN NOW AND EARLY APRIL.

PRECIPITATION...
NEAR TO ABOVE AVERAGE PRECIPITATION FELL ON MUCH OF THE REGION 
DURING FEBRUARY 2014.  HOWEVER...THE SEASONAL ACCMULATION IS
VERY LOW FOR WATERSHEDS IN CALIFORNIA.

STREAMFLOW FORECASTS...
APRIL THROUGH JULY RUNOFF FORECASTS DERIVED FROM ENSEMBLE GUIDANCE 
ARE GENERALLY MUCH BELOW AVERAGE FOR UPPER SACRAMENTO/WEST-SLOPE 
SIERRA NEVADA WATERSHEDS AT THE 50 PERCENT EXCEEDENCE LEVEL.  THE 
APRIL THROUGH SEPTEMBER FORECAST FOR UPPER KLAMATH LAKE IS ABOUT 
62 PERCENT OF AVERAGE.

TO SUMMARIZE... THE FLOOD POTENTIAL IS BELOW AVERAGE FOR ALL 
WATERSHEDS IN CALIFORNIA TYPICALLY AFFECTED BY SPRINGTIME 
SNOWMELT...AS WELL AS OTHER REGIONS IN THE STATE WHERE SNOWMELT 
IS NOT A MAJOR FACTOR IN SPRINGTIME FLOODING.  THIS IS SUPPORTED
BY LOW SOIL MOISTURE CONTENT DUE TO PROLONGED DRY PERIODS DURING
THE PAST YEAR...MUCH BELOW AVERAGE MOUNTAIN SNOWPACKS...AMPLE ROOM 
FOR STORAGE IN MANY OF THE STATE'S LARGE RESERVOIRS ...AND MUCH 
BELOW AVERAGE SPRING RUNOFF FORECASTS AT THE PRESENT TIME.
