THE FLASH FLOOD WATCH CONTINUES FOR

* PORTIONS OF NORTHWEST ARIZONA...CALIFORNIA AND NEVADA... INCLUDING
  THE FOLLOWING AREAS...IN NORTHWEST ARIZONA...LAKE HAVASU AND FORT
  MOHAVE...LAKE MEAD NATIONAL RECREATION AREA... NORTHWEST DESERTS
  AND NORTHWEST PLATEAU. IN CALIFORNIA...CADIZ BASIN...DEATH VALLEY

  RANGE...SOUTHERN CLARK COUNTY...SPRING MOUNTAINS-RED ROCK CANYON
  AND WESTERN CLARK AND SOUTHERN NYE COUNTY.

* THROUGH 9 PM THIS EVENING

* A LARGE UPPER LEVEL DISTURBANCE COULD POTENTIALLY ORGANIZE STRONG
  THUNDERSTORMS WITH HEAVY RAINFALL THROUGH THIS EVENING. WITH
  PLENTY OF MOISTURE IN PLACE ACROSS THE SOUTHERN GREAT BASIN AND
  MOJAVE DESERT...THUNDERSTORMS COULD EASILY PRODUCE ONE TO TWO
  INCHES OF RAINFALL IN A SHORT PERIOD OF TIME. AREAS NEAR RECENT
  BURN SCARS WILL ALSO BE MORE SUSCEPTIBLE TO INCREASED RUNOFF AND
  FLASH FLOODING OR DEBRIS FLOWS.

* MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR
  VEHICLE INTO AREAS WHERE THE WATER COVERS THE ROADWAY SINCE
  FLOOD WATERS ARE USUALLY DEEPER THAN THEY APPEAR. JUST ONE
  FOOT OF FLOWING WATER IS POWERFUL ENOUGH TO SWEEP VEHICLES OFF
  THE ROAD. WHEN ENCOUNTERING FLOODED ROADS MAKE THE SMART
  CHOICE...TURN AROUND...DONT DROWN.

PRECAUTIONARY/PREPAREDNESS ACTIONS...A FLASH FLOOD WATCH MEANS THAT
CONDITIONS MAY DEVELOP THAT LEAD TO FLASH FLOODING. FLASH FLOODING
IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR FORECASTS AND BE PREPARED TO TAKE ACTION SHOULD
FLASH FLOOD WARNINGS BE ISSUED FOR YOUR AREA.
