HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE LAKE CHARLES LA
600 AM CST THU DEC 13 2001

...HEAVY RAINS AND POSSIBLE SEVERE WEATHER TODAY...

AN UPPER LEVEL STORM SYSTEM OVER THE SOUTHWESTERN STATES WILL MOVE
EASTWARD TODAY. SOUTHERLY WINDS AHEAD OF THIS SYSTEM WILL BRING
ABUNDANT GULF MOISTURE ACROSS SOUTHEAST TEXAS...AS WELL AS SOUTHERN
AND CENTRAL LOUISIANA.

THIS RICH MOISTURE COMBINED WITH ENERGY FROM A STORM SYSTEM TO THE
WEST WILL PRODUCE WIDESPREAD SHOWERS AND THUNDERSTORMS. RAINFALL
AMOUNTS WILL AVERAGE BETWEEN 2 AND 3 INCHES WITH LOCALIZED AMOUNTS UP
TO 4 INCHES POSSIBLE TODAY. THE LAKE CHARLES WEATHER OFFICE HAS
ALREADY RECEIVED OVER TWO INCHES OF RAIN SINCE MIDNIGHT.

WINDS WILL FAVOR THUNDERSTORMS TO DEVELOP AND MOVE OVER THE SAME
AREAS FOR LONG PERIODS OF TIME. BECAUSE RELATIVELY MOIST GROUNDS
ALREADY EXIST ACROSS THE AREA...THESE RAINFALL AMOUNTS WILL INCREASE
THE CHANCE FOR FLOODING.

ALL INTERESTS LIVING IN FLOOD PRONE AREAS ALONG RIVERS...STREAMS...
CREEKS AND BAYOUS SHOULD CLOSELY MONITOR THIS WEATHER SITUATION OVER
THE NEXT COUPLE OF DAYS.

IN ADDITION...UPPER LEVEL CONDITIONS WILL BECOME FAVORABLE FOR THE
DEVELOPMENT OF LARGE HAIL AND STRONG WINDS WITH SOME OF THE
THUNDERSTORMS TODAY.

STAY TUNED TO YOUR WEATHER RADIO OR LOCAL MEDIA FOR THE LATEST
WEATHER INFORMATION.
