SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE PHOENIX ARIZONA
1140 AM MST MON SEPT 3 1990

...SCATTERED SHOWERS AND THUNDERSTORMS WITH VERY HEAVY RAIN AND
   STRONG WINDS MOVING OVER WESTERN MOHAVE COUNTY...AND DEVELOPING
   ELSEWHERE IN ARIZONA...

AT 1135 AM MST...WEATHER RADAR AND SATELLITE PHOTOS INDICATED RAPID
DEVELOPMENT OF THUNDERSTORMS IN ARIZONA. THE STRONGEST STORMS WERE
OVER WESTERN MOHAVE COUNTY...AS WELL AS IN THE WHITE MOUNTAIN AREA.
OTHER THUNDERSTORMS WERE INCREASING IN COVERAGE AND INTENSITY IN MUCH
OF THE NORTH AND EAST HALVES OF ARIZONA. GENERAL STORM MOVEMENT WAS
TO THE NORTH AND NORTHEAST AT 20 MPH.

SINCE THE ATMOSPHERE IS UNUSUALLY MOIST...ANY SHOWERS FALLING FROM
THUNDERSTORMS COULD BE QUITE HEAVY.  ITS NOT UNLIKELY THAT A SUDDEN
CLOUDBURST COULD DROP MORE THAN AN INCH OF RAIN IN A SHORT TIME...AND
CAUTION IS URGED.
<
DUE TO THE RANDOM NATURE OF THUNDERSTORMS ITS HARD TO PREDICT PRECISELY
WHO WILL GET THE HEAVY RAIN.  SOIL CONDITIONS AROUND ARIZONA ARE FAIRLY
SATURATED FROM PERVIOUS RAINS...WHICH HEIGHTENS THE POTENTIAL FOR RAPID
RUNOFF IN NORMALLY DRY WASHES AND CANYONS.

HOLIDAY RECREATIONALISTS AROUND THE STATE...INCLUDING BOATERS AND
CAMPERS...SHOULD BE ALERT FOR WEATHER CHANGES IN YOUR AREA TODAY.

BOATERS AND THOSE OUTDOORS ALONG THE LOWER COLORADO RIVER IN MOHAVE
COUNTY SHOULD BE ESPECIALLY ON THE ALERT FOR STRONG THUNDERSTORMS
DUIRING THE NEXT FEW HOURS.

THE VERY HUMID AND UNSTABLE WEATHER PATTERN WILL ALSO CONTINUE OVER
THE STATE THROUGH TUESDAY.
