DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LAS VEGAS NV
200 PM PDT SUN JUL 20 2014

...START OF THE 2014 NORTH AMERICAN MONSOON SEASON BRINGS RELIEF TO
SOME AREAS WHILE EXTREME DROUGHT CONDITIONS EXPAND IN OTHER
PLACES...

SYNOPSIS...AFTER AN EXCEPTIONALLY DRY WINTER AND SPRING ACROSS THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN, 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 30 DAYS, WHICH INCLUDES THE FIRST MONTH OF THE NORTH AMERICAN
MONSOON SEASON, SHOWS MANY AREAS ACROSS SOUTHERN CLARK COUNTY,
CENTRAL AND NORTHERN MOHAVE COUNTY AS WELL AS FAR SOUTHWESTERN
MOHAVE COUNTY AND SOUTHEASTERN SAN BERNARDINO COUNTY RECEIVING 150
PERCENT OR MORE OF THE NORMAL PRECIPITATION FOR THIS 30 DAY PERIOD.
THIS HAS RESULTED IN KEEPING DROUGHT CONDITIONS FROM DETERIORATING
FURTHER IN THESE AREAS.

ELSEWHERE ACROSS THE MOJAVE DESERT AND SOUTHERN GREAT BASIN,
PRECIPITATION AMOUNTS ASSOCIATED WITH THE 2014 NORTH AMERICAN
MONSOON SEASON SO FAR HAVE BEEN LIGHT, WITH THE EXCEPTION OF
NORTHEASTERN ESMERALDA COUNTY AND FAR NORTHEASTERN LINCOLN COUNTY
WHERE TOTALS HAVE BEEN ABOUT 125 PERCENT OR MORE OF NORMAL FOR THE
LAST 30 DAYS. THE FURTHER LACK OF PRECIPITATION IN THESE AREAS
COMBINED WITH INCREASED IMPACTS HAS RESULTED IN DROUGHT CONDITIONS
BECOMING WORSE.

THE LATEST U.S. DROUGHT MONITOR DEPICTS EXTREME DROUGHT, OR D3
CONDITIONS, ACROSS ALL OF ESMERALDA, CENTRAL NYE, SOUTHWEST LINCOLN
AND NORTHWEST CLARK COUNTIES IN NEVADA AS WELL AS FAR NORTHWESTERN
SAN BERNARDINO COUNTY ALL BUT FAR SOUTHEAST INYO COUNTY IN
CALIFORNIA AND A SMALL PORTION OF FAR SOUTHEAST MOHAVE COUNTY IN
ARIZONA. SEVERE DROUGHT CONDITIONS, OR D2, EXIST ACROSS THE
REMAINDER OF THE AREA. DUE TO THE SEVERITY OF THE ONGOING DROUGHT,
DROUGHT CONDITIONS ARE EXPECTED TO PERSIST OR BECOME WORSE ACROSS
THE AREA DESPITE THE 90 DAY OUTLOOK FOR AUGUST, SEPTEMBER AND
OCTOBER FROM THE CLIMATE PREDICTION CENTER SHOWING A 33 PERCENT
CHANCE OR BETTER FOR ABOVE NORMAL PRECIPITATION ACROSS THE AREA.

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.

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 AUGUST
FOR MOST OF INYO AND ESMERALDA COUNTIES AND FOR SEPTEMBER AND
OCTOBER FOR MOST OF INYO COUNTY. NEAR NORMAL WILDFIRE POTENTIAL IS
PREDICTED ELSEWHERE IN THE AREA. HOWEVER, DRY ANTECEDENT CONDITIONS
HAVE CREATED A RISK FOR RAPID WILDFIRE SPREADS WHERE LIGHTNING
STRIKES HAVE IGNITED WILDFIRES DUE TO THE VERY DRY VEGETATION.

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.

WATER SUPPLY

THE FINAL WATER SUPPLY OUTLOOK FOR THE SEASON WAS ISSUED IN JUNE.
THE UPPER COLORADO RIVER BASIN STATES EXPERIENCED MUCH ABOVE AVERAGE
RUNOFF VOLUMES WHILE IN THE LOWER COLORADO RIVER BASIN STATES RUNOFF
VOLUMES WHERE MUCH BELOW NORMAL.

URBAN AREA DROUGHT IMPACTS

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

CLIMATE SUMMARY...

JUNE 2014 WAS ATYPICAL IN MANY WAYS ACROSS THE MOJAVE DESERT AND
SOUTHERN GREAT BASIN. THE MONTH, TYPICALLY ONE OF THE DRIEST ACROSS
THE AREA BASED ON CLIMATOLOGY, FINISHED WITH THE VAST MAJORITY OF
LOCATIONS SEEING NO PRECIPITATION AT ALL. DESPITE THE PASSAGE OF
SEVERAL STORM SYSTEMS, THE LACK OF MOISTURE ASSOCIATED WITH THEM
RESULTED IN SYSTEMS BEING EFFICIENT WIND PRODUCERS, ESPECIALLY FOR
THIS LATE IN THE SEASON, AND VERY LITTLE IN THE WAY OF
PRECIPITATION. ONLY TWO SYSTEMS DURING THE MONTH MANAGED TO PRODUCE
ANY PRECIPITATION. ON JUNE 10TH, ISOLATED SHOWERS AND THUNDERSTORMS
DEVELOPED ACROSS MAINLY THE HIGHER ELEVATIONS OF NORTHERN INYO AND
LINCOLN COUNTIES. FROM JUNE 26TH THROUGH JUNE 27TH, ISOLATED SHOWERS
AGAIN WET PORTIONS OF NORTHERN INYO AND LINCOLN COUNTIES. HOWEVER,
ANY PRECIPITATION THAT FELL WAS VERY LIGHT. SINCE JULY 1ST, PUSHES
OF MOISTURE ASSOCIATED WITH THE NORTH AMERICAN MONSOON HAVE BROUGHT
SOME RELIEF TO THE AREA. ADDITIONAL RELIEF IS POSSIBLE THROUGH THE
END OF THE MONSOON SEASON IN SEPTEMBER FROM AREAS THAT RECEIVE
BENEFICIAL PRECIPITATION FROM SHOWERS AND THUNDERSTORMS.
