...EXCEPTIONAL DROUGHT CONDITIONS PERSIST ACROSS MOST OF THE WFO
HANFORD WARNING/FORECAST AREA WITH EXTREME DROUGHT CONDITIONS 
ELSEWHERE...

SYNOPSIS...

ON JANUARY 17TH 2014...GOVERNOR BROWN DECLARED A DROUGHT EMERGENCY 
FOR THE STATE OF CALIFORNIA. ON APRIL 25TH 2014...THE GOVERNOR 
SIGNED AN EMERGENCY DROUGHT PROCLAMATION. ON SEPTEMBER 16TH 2014... 
GOVERNOR BROWN SIGNED LEGISLATION THAT REGULATES GROUNDWATER FOR THE

THE LATEST DROUGHT MONITOR /OCTOBER 15TH 2015/ DEPICTS ALL OF THE WFO 
HANFORD COUNTY WARNING/FORECAST AREA...EXCEPT THE INDIAN WELLS VALLEY
AND KERN COUNTY DESERT...UNDER EXCEPTIONAL DROUGHT CONDITIONS/CATEGORY
D4/...WHILE THE KERN COUNTY DESERT AND THE INDIAN WELLS VALLEY REMAIN 
UNDER EXTREME DROUGHT CONDITIONS /CATEGORY D3/.

SUMMARY OF IMPACTS...

THERE CONTINUES TO BE SIGNIFICANT MEDIA COVERAGE ON THE ON-GOING DROUGHT
CONDITIONS. THESE REPORTS INCLUDE LOSS OR REDUCTION OF GROUND WATER AND 
STRICTLY IMPOSED WATER CONSERVATION MEASURES IN MANY COMMUNITIES. THERE 
CONTINUES TO BE LOCAL...STATE AND NATIONAL NEWS STORIES ABOUT DRY WELLS 
IN THE SAN JOAQUIN VALLEY...EXCESSIVE GROUNDWATER DRAWDOWN WITH POSSIBLE 
CONTAMINATION AT SPECIFIC DEPTHS AND THEFTS OF WATER FROM MUNICIPAL WATER
SYSTEMS. IN TULARE COUNTY...NEARLY 1800 WELLS HAVE REPORTEDLY RUN DRY AND 
MORE THAN 540 HOUSEHOLDS WITHIN THE COUNTY ARE RELYING ON STATE FUNDED TANKS
AS THEIR PRIMARY SOURCE OF WATER. ABOUT 900 WATER TANKS HAVE BEEN INSTALLED
THROUGHOUT THE SAN JOAQUIN VALLEY WHERE 2 IN 5 ADULTS STRUGGLE TO BUY ENOUGH
TO EAT DESPITE THE BOUNTY OF FRUITS...VEGETABLES AND NUTS THAT SPRING FROM 
THE REGION'S FERTILE SOIL. A FEW SUPPLY COMPANIES ARE DELIVERING WATER TO 
THE MOST NEEDY FAMILIES IN THE SAN JOAQUIN VALLEY FOR BATHING AND DRINKING 
PURPOSES. HOWEVER...THE WATER DEMAND IS MUCH GREATER THAN ITS SUPPLY. 
ADDITIONALLY...OTHERS IN THE AGRIGULTURAL COMMUNITIES OF THE SAN JOAQUIN 
VALLEY ARE SPENDING THOUSANDS OF DOLLARS TO DEEPEN THEIR WELLS.  TO DATE...
MORE THAN 1000 WELL FAILURES IN TULARE COUNTY ALONE REMAIN UNRESOLVED.

THE PERCENTAGE OF NORMAL PRECIPITATION DURING THE PAST 30 DAYS AVERAGED
SLIGHTLY TO MUCH ABOVE NORMAL IN THE SAN JOAQUIN VALLEY AND ADJACENT 
FOOTHILLS AND HIGHER ELEVATIONS OF THE SIERRA FROM FRESNO COUNTY NORTHWARD 
IN ADDITION TO MUCH OF TULARE COUNTY AND THE KERN COUNTY DESERT. PRECIPITATION
OVER THE REMAINDER OF THE CENTRAL CALIFORNIA INTERIOR WAS GENERALLY AT OR
BELOW 80 PERCENT OF NORMAL AND LESS THAN 50 PERCENT OF NORMAL OVER THE
SOUTHERN HALF OF KINGS COUNTY. AS OF JANUARY 20TH...THE PERCENTAGE OF NORMAL
SNOWPACK OVER THE SOUTHERN SIERRA NEVADA WAS 95 PERCENT OF NORMAL. ALTHOUGH
THE SIERRA SNOWPACK IS CONSIDERABLY HIGHER THAN THE PAST FEW SEASONS TO DATE...
THIS IS ONLY ABOUT 46 PERCENT OF THE APRIL 1ST AVERAGE. ADDITIONALLY...WATER
LEVELS REMAIN MUCH LOWER THAN NORMAL IN ALL OF THE MAJOR RESERVOIRS. 
CONCLUSIVELY...NO SIGNIFICANT CHANGE TO THE DROUGHT CLASSIFICATION STATUS
OCCURRED THROUGHOUT THE CENTRAL CALIFORNIA INTERIOR DURING THE PAST 30 DAYS.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE NOAA CLIMATE PREDICTION CENTER 6-10 DAY OUTLOOK ISSUED JANUARY 20TH 
FORECASTS A 60-70 PERCENT CHANCE OF ABOVE NORMAL TEMPERATURES OVER THE CENTRAL
CALIFORNIA INTERIOR WITH A 35-45 PERCENT CHANCE OF ABOVE NORMAL PRECIPITATION.

THE LATEST 8-14 DAY OUTLOOK FORECASTS NEAR NORMAL TEMPERATURES AND A 40-50 
PERCENT CHANCE OF ABOVE NORMAL PRECIPITATION OVER CENTRAL CALIFORNIA.

THE CLIMATE PREDICTION OUTLOOK FOR THE NEXT 30 DAYS...BASED ON DATA FROM THE 
CURRENT STATE OF THE OCEANS AND ATMOSPHERE ALONG WITH CLIMATE MODELS...FROM THE 
NOAA CLIMATE PREDICTION CENTER INDICATES THERE IS AN EQUAL CHANCE OF ABOVE...
NEAR...OR BELOW NORMAL TEMPERATURES ALONG WITH A 40 PERCENT CHANCE OF ABOVE 
NORMAL PRECIPITATION FOR CENTRAL CALIFORNIA.

FOR THE THREE-MONTH PERIOD FEBRUARY-MARCH-APRIL...THE OUTLOOK FAVORS A 35-45
PERCENT CHANCE OF ABOVE-NORMAL TEMPERATURES AND A 40-50 PERCENT CHANCE OF ABOVE
NORMAL PRECIPITATION FOR CENTRAL CALIFORNIA /SEE LINKS BELOW/.

HYDROLOGIC SUMMARY AND OUTLOOK...

A PREVAILING WESTERLY FLOW OVER THE PACIFIC OCEAN WILL CONTINUE TO BRING STORM
SYSTEMS INTO NORTHERN AND CENTRAL CALIFORNIA DURING THE NEXT SEVERAL DAYS AND
POSSIBLY WEEKS. THE STORMS SO FAR THIS WATER YEAR HAVE SUBSTANTIALLY INCREASED
THE SIERRA SNOWPACK AND BROUGHT BENEFICIAL RAIN TO THE LOWER ELEVATIONS OF THE
CENTRAL CALIFORNIA INTERIOR.  THIS PATTERN IS LIKELY TO CONTINUE FOR THE NEXT
30 TO 60 DAYS THANKS TO A FAIRLY STRONG EL NINO WHICH IS FORECAST TO CONTINUE
THROUGH AT LEAST APRIL. DESPITE ABOVE NORMAL PRECIPITATION SINCE OCTOBER 1ST...
THERE HAS BEEN POOR RESPONSE IN THE WATER LEVELS OF MOST OF THE MAJOR RESERVOIRS
THROUGHOUT THE CENTRAL CALIFORNIA INTERIOR AND THERE CONTINUES TO BE A LONG TERM
PRECIPITATION DEFICIT. AN ACCURATE ASSESSMMENT OF THE DROUGHT STATUS THROUGHOUT 
THE CENTRAL CALIFORNIA INTERIOR CANNOT BE REALISTICALLY MADE UNTIL THE SNOWMELT 
SEASON BEGINS THIS SPRING AND RESERVOIRS...IN ADDITION TO THE RIVERS AND STREAMS
ABOVE THE DAMS...EXPERIENCE ADEQUATE RISES IN WATER LEVELS.


NEXT ISSUANCE DATE...

20 FEBRUARY 2016...OR EARLIER IF CONDITIONS CHANGE.
