DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN DIEGO CA
1123 AM PDT TUE AUGUST 26 2014

...EXTREME TO LOCALLY EXCEPTIONAL DROUGHT CONDITIONS CONTINUE OVER
PORTIONS OF SOUTHWESTERN CALIFORNIA...

...THE USDA HAS DECLARED A DROUGHT DESIGNATION FOR SAN BERNARDINO
COUNTY FOR 2014 FOR ELIGIBLE AGRICULTURAL PRODUCERS...

...SMALL GRANTS ARE AVAILABLE FOR DROUGHT IMPACTED ORGANIC FARMERS...

SYNOPSIS...

PORTIONS OF SOUTHWESTERN CALIFORNIA HAVE EXPERIENCED TWO BELOW
AVERAGE RAINFALL SEASONS RESULTING IN A REDUCTION IN RESERVOIR AND
GROUNDWATER LEVELS. THESE CONDITIONS HAVE PROMPTED AN EXTREME
DROUGHT DEPICTION ON THE U.S. DROUGHT MONITOR MAPS WITHIN ORANGE
COUNTY...THE SAN BERNARDINO COUNTY MOUNTAINS...RIVERSIDE COUNTY WEST
OF THE COACHELLA VALLEY...AND SAN DIEGO COUNTY WEST OF THE DESERTS.
MUCH OF ORANGE COUNTY HAS BEEN INCLUDED IN THE EXCEPTIONAL DROUGHT
CATEGORY THAT COVERS THE CENTRAL COAST OF CALIFORNIA. PORTIONS OF
THE HIGH DESERT EAST OF THE APPLE VALLEY...THE COACHELLA VALLEY...
AND MUCH OF THE SAN DIEGO COUNTY DESERTS REMAIN IN THE SEVERE
DROUGHT CATEGORY. THE U.S. DROUGHT MONITOR CLASSIFIES DROUGHT INTO
FIVE CATEGORIES OF INCREASING SEVERITY: ABNORMALLY DRY (D0)...
MODERATE DROUGHT (D1)...SEVERE DROUGHT (D2)...EXTREME DROUGHT
(D3)...AND EXCEPTIONAL DROUGHT (D4).

PLEASE NOTE THAT NEITHER NOAA OR THE NWS DECLARES DROUGHTS. DROUGHTS
IN THE STATE OF CALIFORNIA ARE DECLARED BY THE GOVERNOR THROUGH THE
RECOMMENDATION OF THE CALIFORNIA STATE DEPARTMENT OF WATER RESOURCES
AND THE STATE CLIMATOLOGIST. HOWEVER...LOCAL OFFICIALS CAN DECLARE
LOCAL DROUGHT OR WATER EMERGENCIES AT TIMES WHEN THE STATE OF
CALIFORNIA HAS NOT DECLARED AN OFFICIAL DROUGHT. LOCAL WATER
PURVEYORS CAN ALSO IMPLEMENT VOLUNTARY OR MANDATORY RESTRICTIONS ON
WATER USAGE IN RESPONSE TO CURRENT OR FORECAST WATER SUPPLY
CONDITIONS REGARDLESS OF DROUGHT DECLARATIONS. THIS DROUGHT
STATEMENT PROVIDES A SUMMARY OF PERTINENT INFORMATION TO ENHANCE
PUBLIC AWARENESS OF DROUGHT OR ABNORMALLY DRY CONDITIONS.

SUMMARY OF IMPACTS...

SURFACE STORAGE INCREASES AND GROUNDWATER RESERVES ESTABLISHED OVER
THE PAST FEW YEARS...AND THE AVAILABILITY OF IMPORTED WATER...ARE
EXPECTED TO HELP MUCH OF SOUTHERN CALIFORNIA COPE THIS YEAR. SO
WATER SHORTAGES ARE NOT EXPECTED. HOWEVER...MANY DISTRICTS HAVE
IMPLEMENTED LEVEL-ONE DROUGHT RESTRICTIONS.

THE STATE WATER RESOURCES CONTROL BOARD APPROVED EMERGENCY
REGULATION TO ENSURE WATER AGENCIES AND THEIR CUSTOMERS INCREASE
WATER CONSERVATION IN URBAN SETTINGS OR FACE FINES OR OTHER
ENFORCEMENT. THE REGULATION IS INTENDED TO REDUCE OUTDOOR URBAN
WATER USE. BY LATE SUMMER...DOZENS OF MUNICIPALITIES AND WATER
AUTHORITIES HAD IMPLEMENTED VOLUNTARY AND MANDATORY RESTRICTIONS FOR
WATER USE OUTDOORS.

RECENT MONSOONAL RAINFALL HAS IMPROVED CONDITIONS TEMPORARILY IN THE
LOWER DESERTS...AND INCREASED FUEL MOISTURE OVER THE MOUNTAINS. THIS
HAS LOWERED THE WILDFIRE THREAT TEMPORARILY IN SOME AREAS...HOWEVER
CONDITIONS COULD RAPIDLY DETERIORATE AS WE MOVE INTO THE FALL SEASON
WITHOUT CONTINUED SHOWERS. IF HOT AND WINDY SANTA ANA CONDITIONS
DEVELOP...THE WILDFIRE THREAT WILL INCREASE.

OTHER IMPACTS...

THE LACK OF RAINFALL AND RUNOFF THIS WINTER HAS LOWERED THE FLOW IN
AREA RIVERS...RESULTING IN STRESSES ON INDIGENOUS VEGETATION AND
WILDLIFE.

WELLS FED BY RAINFALL AND LOCAL RUNOFF...MAY BE GOING DRY OR HAVE
ALREADY DRIED UP.


CLIMATE SUMMARY...

ORANGE COUNTY HAS BEEN ONE OF THE DRIEST AREAS IN OUR REGION OVER
THE PAST FEW YEARS. WESTERN REGION CLIMATE CENTER RECORDS FROM THE
SANTA ANA FIRE STATION INDICATE 2013 WAS THE THIRD DRIEST...AND THE
THREE YEAR PERIOD ENDING DECEMBER 2013 WAS THE FIFTH DRIEST. RAINS
HAVE BEEN MORE GENEROUS FARTHER SOUTH IN SAN DIEGO COUNTY WHERE
LINDBERGH FIELD LOGS BOTH 2013 AND THE THREE YEAR PERIOD 2010-2013
AS ONLY THE 20TH DRIEST ON RECORD.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE LATEST 90 DAY OUTLOOKS FROM NOAAS NATIONAL WEATHER SERVICE
CLIMATE PREDICTION CENTER FAVOR SLIGHTLY ABOVE NORMAL TEMPERATURES
AND PRECIPITATION OVER SOUTHERN CALIFORNIA THROUGH NOVEMBER. WE ARE
IN THE DRY SEASON NOW...SO AVERAGE CONDITIONS WOULD RESULT IN LITTLE
RAINFALL...EXCEPT FOR MONSOON EVENTS IN THE MOUNTAINS AND DESERTS.

THE LATEST WINTER OUTLOOK FOR SOUTHERN CALIFORNIA FOR THE DECEMBER
THROUGH FEBRUARY PERIOD CALLS FOR AVERAGE TEMPERATURES AND SLIGHTLY
FAVORS ABOVE NORMAL PRECIPITATION.

HYDROLOGIC SUMMARY AND OUTLOOK...
NO SIGNIFICANT INCREASES CAN BE EXPECTED IN THE LARGER RIVERS AND
RESERVOIRS FOR THE REMAINDER OF THE SEASON.

THE LATEST U.S. SEASONAL DROUGHT OUTLOOK CALLS FOR DROUGHT
CONDITIONS TO PERSIST OR INTENSIFY THROUGH AUTUMN.
