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

SYNOPSIS...

ON JANUARY 17TH...GOVERNOR BROWN DECLARED A DROUGHT EMERGENCY FOR
THE STATE OF CALIFORNIA. ON APRIL 25TH...THE GOVERNOR SIGNED AN
EMERGENCY DROUGHT PROCLAMATION.

THE LATEST DROUGHT MONITOR /MAY 13TH 2014/ NOW DEPICTS ALL OF THE

PARK AND THE KERN COUNTY DESERTS...UNDER EXCEPTIONAL DROUGHT
CONDITIONS /CATEGORY D4/...WHILE YOSEMITE NATIONAL PARK AND THE KERN

DESPITE A PAIR OF MAINLY DRY STORMS THAT MOVED THROUGH CENTRAL
CALIFORNIA ON MAY 5TH-6TH AND 8TH-9TH THROUGH THE FIRST DAYS OF
APRIL...MONTHLY AND SEASONAL RAINFALL AMOUNTS REMAIN WELL BELOW
NORMAL...ESPECIALLY FOR THE SOUTH END OF THE SAN JOAQUIN VALLEY
WHICH HAS BEEN HEAVILY RAIN SHADOWED FOR MUCH OF THE RAIN SEASON.

SUMMARY OF IMPACTS...

MIGRATORY WATERFOWL ARE USING RESIDENTIAL SWIMMING POOLS FOR WATER
AS THEIR NORMAL WATER SOURCES DRY UP.

ON MAY 7TH...THE HANFORD SENTINEL REPORTED ON A STATE DEPARTMENT OF
WATER RESOURCES STUDY IDENTIFYING THE KINGS RIVER AND KAWEAH RIVER
SUB-BASINS AS HAVING THE GREATEST NUMBER OF DEEPENED WELLS. AN AREA
NEAR HURON WAS IDENTIFIED AS HAVING ONE OF THE STATE/S DEEPEST DROPS
IN GROUNDWATER LEVEL.

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...
REDUCTION IN AIR QUALITY DUE TO PERSISTENT STAGNANT AIR...AND LOSS
OR REDUCTION OF GROUND WATER.

CLIMATE SUMMARY...

THE SNOW SURVEY ON MAY 1ST REPORTED THE SNOW-WATER EQUIVALENT FOR
THE SIERRA NEVADA WAS ONLY 18 PERCENT OF NORMAL.

FOR THE PRECIPITATION YEAR /SINCE JULY 1ST 2013/ THROUGH MAY 14TH...
FRESNO RECEIVED 4.78 INCHES OF RAIN OR 43.1 PERCENT OF THE
NORMAL OF 11.10 INCHES. BAKERSFIELD RECEIVED 2.41 INCHES OR 38.1
PERCENT OF THE NORMAL OF 6.32 INCHES.

PRECIPITATION/TEMPERATURE OUTLOOK...

WEATHER MODELS SUGGEST A WEAK/MODERATE STORM WILL IMPACT CENTRAL
CALIFORNIA BEGINNING MAY 19TH AND CONTINUING THROUGH MAY 22ND. EVEN
IF THE STORM WERE TO BRING MODERATE PRECIPITATION TO CENTRAL
CALIFORNIA...IT WOULD NOT BRING ENOUGH PRECIPITATION TO PROVIDE ANY
NOTABLE DROUGHT RELIEF...RATHER A PAUSING OF WORSENING CONDITIONS.

THE NOAA CLIMATE PREDICTION CENTER 6-10 DAY OUTLOOK ISSUED MAY 13TH
FAVORS NEAR- OR ABOVE-NORMAL TEMPERATURES ACROSS CENTRAL
CALIFORNIA...WITH EQUAL CHANCES OF ABOVE-...NEAR-...OR BELOW-NORMAL
PRECIPITATION.

THE LATEST 8-14 DAY OUTLOOK HAS EQUAL CHANCES OF ABOVE-...NEAR- OR
BELOW-NORMAL PRECIPITATION...BUT FAVORS ABOVE-NORMAL TEMPERATURES.

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 FAVORING ABOVE-NORMAL TEMPERATURES FOR CENTRAL
CALIFORNIA...WITH EQUAL CHANCES FOR ABOVE-...NEAR- OR BELOW NORMAL
PRECIPITATION.

FOR THE THREE-MONTH PERIOD MAY-JUNE-JULY...THE ODDS FAVOR ABOVE-
NORMAL TEMPERATURES FOR CENTRAL CALIFORNIA WITH EQUAL CHANCES OF
ABOVE-...NEAR-...OR BELOW-NORMAL PRECIPITATION. 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.
