DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LAS VEGAS NV
1123 PM PDT WED SEP 24 2014

...THE 2014 NORTH AMERICAN MONSOON SEASON BRINGS DROUGHT RELIEF TO
SOME AREAS BUT SPARES OTHERS...

SYNOPSIS...THE 2014 NORTH AMERICAN MONSOON SEASON HAS BROUGHT SOME
RELIEF TO PORTIONS OF OUR DROUGHT-STRICKEN AREA. AS IS TYPICAL WITH
PRECIPITATION IN THE MONSOON SEASON, AREAS THAT RECEIVE RAINFALL SEE
HIGHLY VARIABLE AMOUNTS, OFTEN IN A SHORT DISTANCE. HOWEVER,
PRECIPITATION IN THE LAST 90 DAYS, WHICH ACCOUNTS FOR
THE BULK OF THE NORTH AMERICAN MONSOON SHOWS AREAS ACROSS MOHAVE
COUNTY, EASTERN SAN BERNARDINO COUNTY, THE SPRING MOUNTAINS OF CLARK
COUNTY, LINCOLN COUNTY, MUCH OF CENTRAL AND SOUTHERN NYE COUNTY AND
THE HIGHER ELEVATIONS OF CENTRAL INYO COUNTY RECEIVING 150 PERCENT
OR MORE OF NORMAL PRECIPITATION. THIS HAS RESULTED IN SOME SHORT
TERM IMPROVEMENTS IN DROUGHT CONDITIONS FOR SOME AREAS OF LINCOLN
COUNTY, EASTERN CLARK COUNTY AND MOHAVE COUNTY. ELSEWHERE, THE
ACTIVE MONSOON HAS KEEP THE REGION FROM DETERIORATING FURTHER.

PRECIPITATION HAS LARGELY MISSED MOST OF FAR WESTERN SAN BERNARDINO
COUNTY AND FAR SOUTHWEST INYO COUNTY OVER THE 90 DAYS WHERE 75
PERCENT OR LESS OF THEIR NORMAL PRECIPITATION HAS FALLEN. THE LACK OF
PRECIPITATION IN THESE AREAS COMBINED WITH INCREASED IMPACTS HAS
RESULTED IN DROUGHT CONDITIONS REMAINING STATUS QUO.

THE LATEST U.S. DROUGHT MONITOR DEPICTS IMPROVEMENTS THIS MONTH ARE
ACROSS NORTHERN AND EASTERN LINCOLN COUNTY, FAR NORTHEAST CLARK
COUNTY AND A SMALL PORTION OF SOUTHEAST CLARK COUNTY AND WEST
CENTRAL MOHAVE COUNTY WHICH WERE LOWERED FROM SEVERE DROUGHT (D2) TO
MODERATE DROUGHT (D1) CONDITIONS. EXTREME DROUGHT, OR D3
CONDITIONS, EXISTS ACROSS ALL OF ESMERALDA, CENTRAL NYE, SMALL
PORTION OF SOUTHWEST LINCOLN AND NORTHWEST CLARK COUNTIES IN NEVADA
AS WELL AS FAR NORTHWESTERN SAN BERNARDINO COUNTY ALL BUT FAR
SOUTHEAST INYO COUNTY IN CALIFORNIA. SEVERE DROUGHT CONDITIONS, OR
D2, EXIST ACROSS THE REMAINDER OF SOUTHWEST LINCOLN COUNTY AND CLARK
COUNTY IN NEVADA, CENTRAL SAN BERNARDINO COUNTY AND NORTHEAST MOHAVE
COUNTY. DUE TO THE SEVERITY OF THE ONGOING DROUGHT, DROUGHT
CONDITIONS ARE EXPECTED TO PERSIST ACROSS THE AREA DESPITE THE 90
DAY OUTLOOK FOR OCTOBER, NOVEMBER AND DECEMBER FROM THE CLIMATE
PREDICTION CENTER SHOWING A GREATER PROBABILITY OF ABOVE NORMAL
TEMPERATURES WITH A GREATER PROBABILITY OF ABOVE NORMAL
PRECIPITATION FOR SOUTHEAST CALIFORNIA, FAR SOUTHERN CLARK COUNTY
AND NORTHWEST ARIZONA.

SUMMARY OF IMPACTS...

RECREATION/TOURISM

DUE TO THE LACK OF SPRING RUNOFF FROM SNOWMELT, ALPINE LAKES IN THE
HEADWATERS OF BISHOP CREEK HAVE EXPERIENCED WELL BELOW NORMAL WATER
LEVELS THIS SUMMER. THIS HAS IMPACTED RESORTS THAT CATER TO
FISHERMEN AND OTHERS THAT ENJOY RECREATIONAL ACTIVITIES IN THE HIGH
SIERRA. THE SOUTH LAKE BOAT LANDING HAS BEEN CLOSED FOR THE SUMMER
SEASON DUE TO THE DROUGHT.

LAKE LEVELS ON LAKE MEAD HAVE ALSO CONTINUED TO DECLINE WITH THE
LAKE DROPPING TO A NEW RECORD LOW OF 1081.82 FEET ON JULY 10TH. THIS
BROKE THE PREVIOUS RECORD LOW OF 1081.94 SET ON NOVEMBER 1, 2010.
THE LOW LAKE LEVELS IN LAKE MEAD CONTINUE TO IMPACT RECREATIONAL
BOATING CHANNELS BY REDUCING AREAS THAT BOATS CAN PASS THROUGH. THE
FALLING LAKE LEVEL HAS RESULTED IN THE CONTINUED CLOSURE OF THE ECHO
BAY MARINA AND BOAT LAUNCH RAMP AT ECHO BAY.

NATURAL SPRINGS IN THE SHEEP MOUNTAIN RANGE IN SOUTHERN NEVADA HAVE
RUN DRY IN SOME INSTANCES FORCING HIKERS TO HAVE TO BRING WATER WITH
THEM.

FIRE WEATHER

ABOVE NORMAL SIGNIFICANT WILDFIRE POTENTIAL IS PREDICTED FOR OCTOBER
THROUGH DECEMBER FOR THE WESTERN PORTIONS OF INYO COUNTY AND
SOUTHERN CALIFORNIA MOUNTAINS DUE TO OFF SHORE FLOW SEASON.

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, THE OWENS
VALLEY OF CALIFORNIA AND LINCOLN COUNTY, NEVADA HAVE INCREASED WATER
HAULS FOR LIVESTOCK.

IN LINCOLN COUNTY, FEED SUPPLIES HAVE BEEN DWINDLING DUE TO THE
CONTINUED DRY CONDITIONS. DRIED UP SPRINGS OR REDUCED FLOWS IN THEM
HAVE RESULTED IN A REDUCTION OF THE PRODUCTION OF CALF.

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.

IN LINCOLN COUNTY, ESPECIALLY IN NORTHERN PORTIONS, WILD HORSES HAVE
BEGUN TO COME ONTO GRAZING LANDS AND EAT FORAGE INTENDED FOR GRAZING
CATTLE AND OTHER WILDLIFE. THIS HAS RESULTED IN DAMAGE TO SOME
GRAZING LANDS.

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.

URBAN AREA DROUGHT IMPACTS

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

CLIMATE SUMMARY...

THE NORTH AMERICAN MONSOON HAS BROUGHT SEVERAL SIGNIFICANT RAIN
EVENTS TO PARTS OF FAR EASTERN SAN BERNARDINO COUNTY, MOHAVE COUNTY
AND CLARK COUNTY. EACH OF THESE EVENTS HAS GENERATED A FEW RECORD
RAINFALL EVENTS. NEEDLES CALIFORNIA RECORDED THEIR THIRD WETTEST DAY
ON RECORD WHEN 2.20 INCHES OF RAIN FELL. 2.70 INCHES FOR THE MONTH
MADE IT THE NINTH WETTEST MONTH SINCE RECORDS BEGAN IN 1888. THE
WETTEST LOCATION ACROSS THE AREA AT AN OFFICIAL CLIMATE STATION FOR
AUGUST WAS 4.11 INCHES AT DIAMOND M RANCH, ARIZONA. THIS RANKED AS
THE 3RD WETTEST AUGUST ON RECORD AT DIAMOND M RANCH DATING BACK TO
1999. THE WETTEST AUGUST AT DIAMOND M RANCH REMAINS 4.69 INCHES IN
2007.

THE BENEFICIAL RAINS THAT FELL FROM THE REMNANTS OF NORBERT IN EARLY
SEPTEMBER HAVE BEEN ENOUGH TO BRING SOME SHORT TERM RELIEF IN
DROUGHT CONDITIONS TO PARTS OF EASTERN LINCOLN COUNTY, EASTERN CLARK
COUNTY AND MOHAVE COUNTY.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE LATEST SEASONAL FORECAST (OCTOBER THROUGH DECEMBER)...ISSUED BY
THE CLIMATE PREDICTION CENTER...THERE IS HIGHER CONFIDENCE FOR ABOVE
NORMAL TEMPERATURES ACROSS CALIFORNIA AND WESTERN NEVADA WITH

HYDROLOGIC SUMMARY AND OUTLOOK...

AT THE END OF AUGUST, LAKE POWELL`S ELEVATION WAS 3605.8 FEET OR 51
PERCENT CAPACITY. MEANWHILE, LAKE MEAD`S ELEVATION WAS 1081.6 FEET
OR 39 PERCENT CAPACITY. THE LAKE MEAD ELEVATION IS PROJECTED TO STAY
AROUND 1080 FEET AND REMAIN AROUND THAT ELEVATION THROUGH NOVEMBER
2014. THE BUREAU OF RECLAMATION HAS PROJECTED TO RELEASE 9.0 MAF
FROM LAKE POWELL IN 2015...UP FROM THE 7.48 MAF PROJECTED FOR THE
2014 WATER YEAR. HOWEVER, THIS WILL HAVE NO AFFECT ON LAKE MEAD
WATER LEVELS AS THE BUREAU OF RECLAMATION PROJECTS WATER LEVELS
BELOW 1080 FEET BY THE END OF WATER YEAR 2015.
