DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LAS VEGAS NV
1258 AM PDT TUE JUN 24 2014

...EXCEPTIONALLY DRY WINTER SEASON HAS DROUGHT CONDITIONS WORSENING
ACROSS PARTS OF THE SOUTHERN GREAT BASIN AND MOJAVE DESERT...

SYNOPSIS...THE FINAL MONTH OF THE COLD SEASON PRECIPITATION SEASON
BROUGHT LITTLE RELIEF TO THE MOJAVE DESERT AND SOUTHERN GREAT BASIN.
ONLY TWO STORM SYSTEMS IMPACTED THE AREA WITH ANY PRECIPITATION
DURING APRIL 2014 AND THE AMOUNTS THAT FELL WERE MEAGER. MAY AND
JUNE 2014 HAVE CONTINUED THE DRY TREND, WITH ANY PRECIPITATION
FALLING BEING VERY LIGHT AND SPOTTY IN NATURE. THE LACK OF ANY
RECENT PRECIPITATION COMBINED WITH THE WELL BELOW NORMAL WINTER
PRECIPITATION IN MOST LOCATIONS HAS ALLOWED DROUGHT CONDITIONS TO
CONTINUE TO BECOME WORSE ACROSS THE AREA.

THE LATEST U.S. DROUGHT MONITOR DEPICTS EXTREME DROUGHT ACROSS THE
EASTERN SIERRA SLOPES AND OWENS VALLEY OF INYO COUNTY. MODERATE TO
SEVERE DROUGHT CONDITIONS ARE PRESENT ACROSS THE REMAINDER OF THE
SOUTHERN GREAT BASIN AND MOJAVE DESERT. DROUGHT CONDITIONS ARE
EXPECTED TO PERSIST OR BECOME WORSE AS THERE ARE HIGHER THAN NORMAL
CHANCES OF BELOW NORMAL PRECIPITATION FOR THE NEXT 3 MONTHS.

SUMMARY OF IMPACTS...

RECREATION/TOURISM

DUE TO THE LACK OF SPRING RUNOFF FROM SNOWMELT, ALPINE LAKES IN THE
HEADWATERS OF BISHOP CREEK WILL EXPERIENCE WELL BELOW NORMAL WATER
LEVELS THIS SUMMER. THIS WILL IMPACT RESORTS THAT CATER TO FISHERMEN
AND OTHERS THAT ENJOY RECREATIONAL ACTIVITIES IN THE HIGH SIERRA.

FIRE WEATHER

ABOVE NORMAL SIGNIFICANT FIRE POTENTIAL IS PREDICTED FOR JUNE AND
JULY FOR THE MOUNTAINS OF SOUTHERN NEVADA AND MOUNTAINS AND
FOOTHILLS IN INYO COUNTY. AUGUST THROUGH SEPTEMBER OUTLOOK...ABOVE
NORMAL SIGNIFICANT FIRE POTENTIAL WILL CONTINUE FOR MOST OF
CALIFORNIA, NEVADA. SUMMER THUNDERSTORMS COULD BRING SOME RELIEF TO
PARTS OF ARIZONA.

AGRICULTURAL

THE UNITED STATES DEPARTMENT OF AGRICULTURE DESIGNATED CLARK, NYE,
LINCOLN AND ESMERALDA COUNTIES IN NEVADA, MOHAVE COUNTY IN ARIZONA
AND INYO AND SAN BERNARDINO COUNTIES IN CALIFORNIA AS PRIMARY
NATURAL DISASTER AREAS DUE TO THE RECENT DROUGHT. ALL FARM AND RANCH
OPERATORS IN THOSE COUNTIES ALL QUALIFY FOR LOW INTEREST EMERGENCY
LOANS FROM THE USDA FARM SERVICE AGENCY, PROVIDED ELIGIBILITY
REQUIREMENTS ARE MET.

LIVESTOCK PRODUCERS USING RANGELAND MAY NEED TO PROVIDE SUPPLEMENTAL
FEED FOR CATTLE. SOME RANCHERS IN NORTHWEST ARIZONA AND THE OWENS
VALLEY HAVE INCREASED WATER HAULS FOR LIVESTOCK.

WILDLIFE

A VARIETY OF WILDLIFE LOCATED IN THE HUALAPAI MOUNTAINS IN SOUTHERN
MOHAVE COUNTY, INCLUDING ELK, BLACK BEAR AND MOUNTAIN LION MAY
VENTURE INTO KINGMAN OR OTHER POPULATED AREAS LOOKING FOR FOOD AND
WATER.

GROUND WATER

INYO COUNTY SUPERVISORS PASSED A THREE-PAGE DROUGHT PROCLAMATION FOR
INYO COUNTY. THEY NOTED THE SERIOUSNESS OF THE SITUATION BY
POINTING OUT THE VERY LOW SNOWPACK IN THE SOUTHERN SIERRA, DRY WELLS
AROUND BISHOP AND CONCERNS ABOUT USE OF WATER ON THE DRY LAKE AND
THE NEED FOR LOS ANGLES DEPARTMENT OF WATER AND POWER AND INYO
COUNTY TO PLAN FOR DRY TIMES.

WATER SUPPLY

THE JUNE-JULY VOLUME RUNOFF FOR THE EASTERN SLOPES OF THE SOUTHERN
SIERRA IS WELL BELOW 50 PERCENT OF NORMAL.

AN IMPRESSIVE RUNOFF SEASON WILL CONTINUE WELL INTO JULY FOR THE
COLORADO RIVER BASIN. THE JUNE 1 OUTLOOK FOR JUNE-JULY STREAMFLOW
RUNOFF VOLUME INTO LAKE POWELL WAS 120 PERCENT OF NORMAL OR 4.5
MILLION ACRE-FEET. THE DRY WEATHER CONTRIBUTED A VERY POOR RUNOFF
SEASON FOR THE VIRGIN RIVER.

URBAN AREA DROUGHT IMPACTS

SOME LANDSCAPE VEGETATION HAS DRIED OUT IN THE LAS VEGAS VALLEY,
ESPECIALLY WHERE MINIMAL IRRIGATION TAKES PLACE.

CLIMATE SUMMARY...

THE PASSAGE OF A FEW STORM SYSTEMS BROUGHT ABOVE NORMAL
PRECIPITATION TO PARTS OF INYO AND ESMERALDA COUNTY IN MAY. SEVERAL
INCHES OF SNOW EVEN FELL ALONG THE EASTERN SLOPES OF THE SIERRA.
ELSEWHERE, THE SPRING CONTINUED TO BE DRY AND WARM. DROUGHT
CONDITIONS ARE FORECAST TO PERSIST AS WE CONTINUE THROUGH JUNE ONE
OF OUR DRIEST MONTHS. THE SUMMER MONSOON MAY BRING SLIGHT RELIEVE TO
PORTIONS OF ARIZONA.
