DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
1100 PM PDT THU MAR 20 2014

...EXCEPTIONAL DROUGHT CONDITIONS ACROSS MOST OF THE CENTRAL
CALIFORNIA INTERIOR WITH EXTREME DROUGHT CONDITIONS ELSEWHERE...

SYNOPSIS...

ON JANUARY 17TH...GOVERNOR BROWN DECLARED A DROUGHT EMERGENCY FOR
THE STATE OF CALIFORNIA. THE LATEST DROUGHT MONITOR /MARCH 18TH
2014/ NOW DEPICTS ALL OF THE CENTRAL CALIFORNIA INTERIOR...EXCEPT
YOSEMITE NATIONAL PARK AND THE KERN COUNTY DESERTS...UNDER
EXCEPTIONAL DROUGHT CONDITIONS /CATEGORY D4/...WHILE YOSEMITE
NATIONAL PARK AND THE KERN COUNTY DESERTS REMAIN UNDER EXTREME
DROUGHT CONDITIONS /CATEGORY D3/.

DESPITE A SERIES OF WEAK STORMS THAT MOVED THROUGH CENTRAL
CALIFORNIA THROUGH THE FIRST DAYS OF MARCH...MONTHLY AND SEASONAL
RAINFALL AMOUNTS REMAIN WELL BELOW NORMAL...ESPECIALLY FOR THE
SOUTH END OF THE SAN JOAQUIN VALLEY WHICH WAS HEAVILY RAIN
SHADOWED IN FEBRUARY. MARCH NORMALLY IS ONE OF THE THREE WETTEST
MONTHS OF THE YEAR WITH A 30-YEAR NORMAL RAINFALL OF 2.03 INCHES
FOR FRESNO AND 1.21 INCH FOR BAKERSFIELD. THROUGH MARCH
20TH...FRESNO HAD RECEIVED ONLY 0.02 INCH OF RAIN SINCE MARCH
1ST...AND BAKERSFIELD HAD RECEIVED 0.04 INCH.

THE MEDIUM-RANGE MODELS SUGGEST A STORM WILL IMPACT THE CENTRAL
CALIFORNIA INTERIOR BEGINNING AROUND MARCH 26TH...ALTHOUGH THERE
WERE CONSIDERABLE DIFFERENCES BETWEEN THE GFS AND ECMWF AS TO STORM
TIMING...TRACK AND STRENGTH. EVEN IS THE STORM WERE TO BRING
MODERATE PRECIPITATION TO THE CENTRAL CALIFORNIA INTERIOR...IT WOULD
NOT BRING ENOUGH PRECIPITATION TO PROVIDE ANY NOTABLE DROUGHT
RELIEF...RATHER A PAUSING OF WORSENING CONDITIONS. THE 8 TO 14 DAY
PRECIPITATION OUTLOOK ISSUED MARCH 20TH HAS EQUAL CHANCES OF
ABOVE-...NEAR- OR BELOW-NORMAL RAINFALL FOR THE REGION. THERE
IS AN INCREASED RISK OF BELOW AVERAGE RAINFALL THROUGH JUNE.
DROUGHT IMPACTS ARE BECOMING MORE WIDESPREAD AND VISIBLE.

SUMMARY OF IMPACTS...

ON FEBRUARY 14TH...PRESIDENT OBAMA VISITED THE WEST SIDE OF THE SAN
JOAQUIN VALLEY TO DISCUSS THE IMPACTS OF THE DROUGHT WITH AFFECTED
FARMERS. ON FEBRUARY 21ST...THE U.S. GOVERNMENT ANNOUNCED THAT THERE
WOULD BE ZERO ALLOCATIONS OF WATER TO FARMERS IN THE SAN JOAQUIN
VALLEY THIS SUMMER. ON MARCH 18TH...THE CALIFORNIA STATE WATER
CONTROL BOARD ANNOUNCED THAT RESTRICTIONS ON WATER PUMPING WOULD BE
REDUCED. HOWEVER...THE HANFORD SENTINEL /MARCH 19...PAGE A1/
REPORTED THAT ONLY SENIOR RIPARIAN RIGHTS HOLDERS ALONG THE
ORIGINAL CHANNEL OF THE SAN JOAQUIN RIVER WERE LIKELY TO GET ANY
SIGNIFICANT IRRIGATION DELIVERIES.

THERE CONTINUES TO BE SIGNIFICANT MEDIA COVERAGE ON THE ON-GOING
DROUGHT CONDITIONS. THESE REPORTS INCLUDE DISCUSSION OF SIGNIFICANT
RE-ALLOCATION OF WATER RESOURCES FROM THE EAST TO WEST SIDE OF THE
SAN JOAQUIN VALLEY...FARMERS FORGOING PLANTING OF SOME CROPS...A
DECREASE IN THE SNOW-RELATED TOURISM ACTIVITY IN THE SOUTHERN
SIERRA NEVADA...REDUCTION IN AIR QUALITY DUE TO PERSISTENT STAGNANT
AIR...AND LOSS OR REDUCTION OF GROUND WATER.

CLIMATE SUMMARY...

FOR THE WATER YEAR /SINCE JULY 1ST 2013/ THROUGH MARCH 20TH...
FRESNO HAS RECEIVED 3.43 INCHES OF RAIN OR 36.9 PERCENT OF THE
NORMAL OF 9.29 INCHES. BAKERSFIELD RECEIVED 1.55 INCH OR 29.1
PERCENT OF THE NORMAL OF 5.32 INCHES.

THROUGH MARCH 19TH...THE AVERAGE TEMPERATURE AT BAKERSFIELD WAS 61.7
DEGREES...WHICH TIED FOR THE 7TH WARMEST FIRST 20 DAYS OF MARCH ON
RECORD. /THE WARMEST FIRST 20 DAYS WAS IN 1972 WITH AN AVERAGE
TEMPERATURE OF 65.8 DEGREES./ FRESNO HAD AN AVERAGE TEMPERATURE OF
62.3 DEGREES...FOR ITS THIRD WARMEST FIRST 20 DAYS OF MARCH ON
RECORD. /THE WARMEST FOR FRESNO WAS IN 1934...WITH AN AVERAGE
TEMPERATURE OF 64.1 DEGREES./

PRECIPITATION/TEMPERATURE OUTLOOK...

THE FORECAST FOR THE NEXT SEVEN DAYS FOR THE CENTRAL CALIFORNIA
INTERIOR CALLS FOR A STORM TO MOVE THROUGH THE REGION BEGINNING
AROUND MARCH 26TH...ALTHOUGH THERE IS CONSIDERABLE UNCERTAINTY AT
THIS TIME AS TO THE EXPECTED IMPACTS.

THE NOAA CLIMATE PREDICTION CENTER 6-10 DAY OUTLOOK ISSUED MARCH 20TH
CALLS FOR EQUAL CHANCES OF ABOVE-...NEAR- OR BELOW-NORMAL
PRECIPITATION ACROSS THE CENTRAL CALIFORNIA INTERIOR...AS DOES THE
LATEST 8-14 DAY OUTLOOK.

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/S INDICATES
THE ODDS ARE FAVOR BELOW-NORMAL PRECIPITATION. THE ODDS FAVOR ABOVE-
NORMAL TEMPERATURES FOR THE CENTRAL CALIFORNIA INTERIOR.

FOR THE THREE-MONTH PERIOD APRIL-MAY-JUNE...THE ODDS FAVOR BELOW-
NORMAL PRECIPITATION AND ABOVE-NORMAL TEMPERATURES FOR THE CENTRAL
CALIFORNIA INTERIOR. GRAPHICS FOR THESE OUTLOOKS CAN BE FOUND ONLINE
/SEE LINKS BELOW/.

HYDROLOGIC SUMMARY AND OUTLOOK...

WITH NO ADDITIONAL SIGNIFICANT WIDESPREAD PRECIPITATION EXPECTED
OVER THE AREA FOR THE NEXT SEVERAL DAYS...NO INCREASES IN AREA
RIVERS AND RESERVOIRS WATER LEVELS ARE EXPECTED. THE CURRENT DROUGHT
OUTLOOK FROM THE NOAA CLIMATE PREDICTION CENTER INDICATES CURRENT
DROUGHT LEVELS ARE LIKELY TO PERSIST THROUGH THE NEXT THREE MONTHS.
