SYNOPSIS...TROPICAL MOISTURE PULLED NORTHWARD AHEAD OF A STRONG AREA
OF LOW PRESSURE PRODUCING ANOTHER ROUND OF HEAVY RAINFALL ACROSS
EASTERN LINCOLN AND EASTERN CLARK COUNTIES IN NEVADA AS WELL AS
MOHAVE COUNTY IN ARIZONA ON SEPTEMBER 26 AND 27. THE AREA AROUND
SOUTHERN MOHAVE COUNTY EXPERIENCED ADDITIONAL RAIN ON OCTOBER 8 WHEN
SOME AREAS SOUTHEAST OF KINGMAN ALONG THE HUALAPAI MOUNTAIN
FOOTHILLS REPORTED BETWEEN ONE AND ONE AND A HALF INCHES. A SYSTEM
IN LATE SEPTEMBER PRODUCED THE FIRST NOTEWORTHY ACCUMULATING SNOW OF
THE FALL SEASON ABOVE 9000 FEET IN THE SOUTHERN SIERRA NEVADA AND
SPRING MOUNTAINS IN CLARK COUNTY NEVADA.

THE LATEST U.S. DROUGHT MONITOR DEPICTS SLIGHT IMPROVEMENT THIS
MONTH ACROSS NORTHERN MOHAVE COUNTY WERE LOWERED FROM SEVERE DROUGHT
(D2) TO MODERATE DROUGHT (D1) CONDITIONS. NO CHANGE ELSEWHERE, AS
EXTREME DROUGHT, OR D3 CONDITIONS, EXISTS ACROSS ALL OF ESMERALDA,

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

THE 90 DAY OUTLOOK FOR NOVEMBER, DECEMBER AND JANUARY 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

RESORTS THAT CATER TO FISHERMEN AND OTHERS THAT ENJOY RECREATIONAL
ACTIVITIES IN THE HIGH SIERRA WERE AFFECTED BY LOW WATER LEVELS IN
ALPINE LAKES. THE SOUTH LAKE BOAT LANDING WAS CLOSED FOR THE SUMMER
SEASON DUE TO THE DROUGHT.

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 THE
REST OF OCTOBER THROUGH NOVEMBER FOR THE EASTERN SLOPES OF THE
SOUTHERN SIERRA IN INYO COUNTY AND SOUTHERN CALIFORNIA MOUNTAINS DUE
TO OFF SHORE FLOW SEASON. FOR DECEMBER AND JANUARY, THE OUTLOOK
CALLS FOR THE MOUNTAINS OF SOUTHERN CALIFORNIA TRANSITIONING TO
NORMAL SIGNIFICANT WILDFIRE POTENTIAL.

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.

WILDLIFE

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 BROUGHT SEVERAL SIGNIFICANT RAIN
EVENTS TO PARTS OF FAR EASTERN SAN BERNARDINO COUNTY, MOHAVE COUNTY
AND CLARK COUNTY IN SEPTEMBER. SOME LOCATIONS SAW OVER 2 INCHES OF
RAIN ONE A SINGLE DAY. THE TOTAL MONSOON SEASON PRECIPITATION AT
DIAMOND M RANCH, ARIZONA WAS 13.84 INCHES WHICH RANKED AS THE
WETTEST ON RECORD BACK TO 1999. THE PREVIOUS RECORD WAS 12.64 INCHES
SET IN 2007.

THE BENEFICIAL RAINS THAT FELL IN SEPTEMBER HAVE BEEN ENOUGH TO
BRING SOME SHORT TERM RELIEF IN DROUGHT CONDITIONS TO PARTS OF
EASTERN PORTIONS OF LINCOLN, CLARK AND SAN BERNARDINO COUNTIES AND
MOHAVE COUNTY.
