...THUNDERSTORMS DEVELOPING RAPIDLY IN SOUTHERN ARIZONA...

SINCE ABOUT 3 PM MST...THUNDERSTORMS HAVE BEEN DEVELOPING QUITE
RAPIDLY IN PARTS OF SOUTHERN ARIZONA. THE LARGEST AREA OF NEW THUNDER
STORMS WAS AROUND TUCSON...OTHERS WERE CLUSTERED NEAR GILA BEND AND IN
LA PAZ AND EXTREME NORTHERN YUMA COUNTIES.

RADAR GAVE INDICATIONS THAT SOME OF THESE THUNDERSTORMS WERE CAUSING
HAIL AND HEAVY RAIN. THE ONES AROUND SALOME AND QUARTSITE...IN LA PAZ
COUNTY...APPEARED TO CONTAIN CONSIDERABLE HAIL.

ALL OF THESE THUNDERSTORMS ARE MOVING TOWARD THE NORTH AROUND 10 TO 20
MPH. THIS RAPID MOVEMENT DECREASES THE RISK OF FLASH FLOODING TO SOME
EXTENT. BUT ANY DESERT THUNDERSTORM THAT CAUSES AN INCH OR MORE OF
RAIN CAN CAUSE FLOODING IN WASHES AND HIGHWAY DIPS. SO MOTORISTS
SHOULD USE CAUTION.

THUNDERSTORM ACTI}VITY IS LIKELY TO CONTINUE INCREASING FOR ANOTHER TWO
OR THREE HOURS...REACHING A PEAK JUST BEFORE SUNSET. STAY TUNED TO
RADIO OR TV FOR THE LATEST WEATHER UPDATES.
