DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN DIEGO CA
416 PM PDT THU MAR 20 2014

...GOVERNOR JERRY BROWN DECLARES A DROUGHT STATE OF EMERGENCY FOR
CALIFORNIA ON JANUARY 17TH 2014...

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

...EXTREME DROUGHT CONDITIONS OVER PORTIONS OF SOUTHWESTERN
CALIFORNIA...

SYNOPSIS...

PORTIONS OF SOUTHWESTERN CALIFORNIA HAVE EXPERIENCED TWO BELOW
AVERAGE RAINFALL SEASONS RESULTING IN A REDUCTION IN RESERVOIR AND
GROUNDWATER LEVELS. THE MUCH DRIER THAN USUAL VEGETATION FOR
LATE-WINTER HAS CONTRIBUTED TO A HEIGHTENED WILDFIRE CONCERN. THESE
CONDITIONS WERE ELEVATED TO AN EXTREME DROUGHT DEPICTION (D3) ON THE
U.S. DROUGHT MONITOR MAPS WITHIN ORANGE COUNTY IN MID JANUARY 2014
AND EXPANDED TO INCLUDE ALL MOUNTAIN AREAS AND POINTS WEST TO THE
COAST IN FEBRUARY. THE LOWER DESERTS AND EASTERN PORTIONS OF THE
HIGH DESERT IN SAN BERNARDINO COUNTY 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...

AT THIS TIME...IMPACTS HAVE BEEN LIMITED IN EXTREME SOUTHWESTERN
PORTIONS OF THE STATE DUE TO THE AVAILABILITY OF IMPORTED WATER.
HOWEVER...THE LACK OF PRECIPITATION HAS ALLOWED VEGETATION TO DRY TO
CRITICAL LEVELS IN MANY AREAS...INCREASING THE POTENTIAL FOR
WILDFIRES. RECENT RAINS SHOULD PROVIDE FOR SOME GREEN UP IN THE
COMING WEEKS AND HELP TO DECREASE WILDFIRE POTENTIAL TEMPORARILY.
THE WARM AND DRY WEATHER HAS ALSO REDUCED THE AVAILABILITY OF RANGE
LAND GRASSES FOR LIVESTOCK. WHERE LOCAL WELLS ARE FED BY RAINFALL
AND LOCAL RUNOFF...SOME SHALLOW WELLS MAY BE GOING DRY OR HAVE
ALREADY DRIED UP. IN ADDITION...THE LACK OF RAINFALL AND RUNOFF THIS
WINTER HAS LOWERED THE FLOW IN THE SAN DIEGO RIVER...RESULTING IN
STRESSES ON THE VEGETATION AND WILDLIFE.

THE METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA HAS DOUBLED
ITS PREVIOUS $20 MILLION ALLOTMENT FOR ITS CONSERVATION REBATE
PROGRAM IN ANTICIPATION OF GREATER DEMAND. IT HAS ALSO APPROVED A
WATER SUPPLY ALERT...REQUESTING ITS MEMBER AGENCIES IN RIVERSIDE AND
SAN BERNARDINO COUNTIES TO VOLUNTARILY IMPLEMENT AND ENFORCE
ORDINANCES THAT LIMIT OUTDOOR IRRIGATION...PROHIBIT RUNOFF AND OTHER
SIMILAR MEASURES. VOLUNTARY WATER CONSERVATION OF 20% HAS BEEN
ENCOURAGE ELSEWHERE ACROSS SOUTHERN CALIFORNIA BY LOCAL OFFICIALS.

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.

A WELL-DEVELOPED MONSOON LAST SUMMER HELPED TO RAISE SEASONAL
RAINFALL IN THE MOUNTAINS AND DESERTS.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE LATEST 30 AND 90 DAY OUTLOOKS FROM THE CLIMATE PREDICTION CENTER
CONTINUE TO FAVOR DRIER THAN NORMAL CONDITIONS ACROSS THE REGION.
FOR APRIL...THERE IS A 70-74% CHANCE OF BELOW NORMAL PRECIPITATION
AND AN 80% CHANCE OF BEING WARMER THAN NORMAL. FOR THE APRIL-JUNE
PERIOD...THERE IS A 65% CHANCE OF BELOW NORMAL PRECIPITATION AND AN
80% CHANCE OF BEING WARMER THAN NORMAL. HOWEVER...THE LATEST 6-10
AND 8-14 DAY OUTLOOKS SUGGEST EQUAL CHANCES OF WET OR DRY CONDITIONS
FOR THE END OF MARCH THROUGH EARLY APRIL.

HYDROLOGIC SUMMARY AND OUTLOOK...
NO SIGNIFICANT INCREASES CAN BE EXPECTED IN THE LARGER RIVERS AND
RESERVOIRS IF PRECIPITATION RETURNS...DUE TO THE DROUGHT. EVEN WITH
HEAVY PRECIPITATION...THE LARGER RIVERS MAY TAKE SOME TIME TO
RESPOND.

THE LATEST U.S. SEASONAL DROUGHT OUTLOOK CALLS FOR DROUGHT
CONDITIONS TO PERSIST OR INTENSIFY THROUGH JUNE 2014.

NEXT SCHEDULED ISSUANCE DATE...
THE NEXT SCHEDULED DROUGHT INFORMATION STATEMENT UPDATE WILL BE
ISSUED ON OR ABOUT APRIL 18TH.
