SPECIAL WEATHER STATEMENT

239 PM MST MON MAR 7 1994

...THUNDERSTORMS CONTINUE OVER SOUTHWEST ARIZONA...

AT 215 PM MST, A THUNDERSTORM WAS OBSERVED MOVING INTO THE FOOTHILLS
SECTION OF THE YUMA AREA. OTHER THUNDERSTORMS WERE DEVELOPING IN
NORTHERN YUMA COUNTY. IN ADDITION, LIGHTNING DETECTORS INDICATED
THUNDERSTORM ACTIVITY BETWEEN PARKER AND BOUSE IN NORTHERN LA PAZ
COUNTY. SATELLITE IMAGERY REVEALED THAT ANOTHER AREA OF SHOWERS AND
THUNDERSTORMS WAS LOCATED IN SOUTHEAST CALIFORNIA AND NORTHERN BAJA
CALIFORNIA, WHICH SHOULD MOVE INTO YUMA AND LA PAZ COUNTIES BY THIS
EVENING.

NORTHERN LA PAZ COUNTY RECEIVED FROM 0.50 TO 0.80 INCHES OF RAIN FROM A
PREVIOUS ROUND OF THUNDERSTORMS EARLY THIS MORNING. ADDITIONAL RAINFALL
WILL CAUSE FLOODING OF LOW SPOTS IN AREA ROADS. HOWEVER, THUNDERSTORMS
ANYWHERE IN SOUTHWEST ARIZONA THIS AFTERNOON AND EVENING HAVE THE
POTENTIAL TO PRODUCE LOCALLY HEAVY RAIN, SMALL HAIL, STRONG GUSTY WINDS
AND DEADLY LIGHTNING.

AN UPPER LOW SOUTH OF SAN DIEGO WAS RESPONSIBLE FOR THE THUNDERSTORMS,
AND ITS SLOW EASTWARD MOVEMENT MEANS THAT THIS ACTIVITY WILL PERSIST
WELL INTO THE EVENING HOURS. SHOWERS WILL DECREASE FROM WEST TO EAST BY
MIDNIGHT AS THE LOW DRIFTS EAST.

IF YOU ARE OUTDOORS...MOVE TO A PLACE OF SHELTER IMMEDIATELY IF A
STORM APPROACHES.  MOTORISTS SHOULD REMAIN ALERT FOR REDUCED
VISIBILITIES DURING DOWNPOURS OF RAIN.  STREETS MAY FLOOD QUICKLY.
