Severe Thunderstorm Warning 349, NWS Atlanta, GA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
330 PM EDT SAT SEP 14 2002

OVERVIEW: HANNA WILL MOVE ACROSS NORTH GEORGIA TONIGHT...BRINGING
HEAVY RAIN TO THE AREA. WEAK TROUGHINESS CONTINUES OVER THE AREA FOR
A COUPLE OF DAYS...THEN HIGH PRESSURE BUILDS DOWN THE EAST COAST.
HOWEVER SOUTHEAST WINDS KEEP MOISTURE OVER US THROUGH MOST OF THE
WEEK.

SHORT TERM: HANNA TO TRACK ACROSS NORTH GEORGIA WITH HEAVY RAIN TO
THE SOUTH AND EAST OF THE TRACK. RAIN TAPERS OFF SUNDAY...THEN
CHANCE POPS MONDAY AND TUESDAY.

EXTENDED: MOISTURE REMAINS OVER THE AREA...BUT DYNAMICS REMAIN WEAK
UNTIL THE END OF THE EXTENDED PERIOD WHEN A FRONT MAY APPROACH. THIS
IS STILL IN QUESTION AS THE AVN STILL HAS THE STRONGEST TROUGH. ALSO
ANOTHER QUESTION MARK IS THE TROPICAL SYSTEM SHOWN TO MOVE INTO THE
BAHAMAS.

FORECAST CONFIDENCE: MODERATE...BECOMING FAIRLY LOW TOWARD THE END
OF THE EXTENDED.

HAZARDOUS WEATHER OUTLOOK FOR NORTH AND CENTRAL GEORGIA
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
1100 AM EDT SAT SEP 14 2002

...ISOLATED TORNADOS AND FLASH FLOODING POSSIBLE LATE TODAY AND
   TONIGHT.

...SYNOPSIS...
A WEAKENED FORM OF TROPICAL STORM HANNA WILL MOVE ACROSS THE NORTH
HALF OF GEORGIA TONIGHT.

.PRIMARY HAZARD...
THE PRIMARY HAZARD WILL BE THE POSSIBILITY FOR BRIEF ISOLATED
TORNADOS...IN ADDITION TO THE POTENTIAL FOR FLASH FLOODING DUE TO
HEAVY RAIN. THE MOST LIKELY TIME FOR TORNADOS WILL BE LATE THIS
AFTERNOON AND EARLY EVENING...WITH A DECREASING THREAT AFTER THAT.
THE BEST LOCATION WILL BE ALONG AND JUST EAST OF THE STORMS PATH.
THE BEST TIME FOR FLASH FLOODING WILL BE LATE THIS AFTERNOON AND
TONIGHT...AS THE REMNANTS OF HANNA APPROACH AND MOVE ACROSS THE
STATE. THE BEST LOCATION FOR FLASH FLOODING WILL BE ALONG AND EAST
OF THE STORMS PATH.

.DISCUSSION...
THERE IS A RISK OF TORNADOS AND FLASH FLOODING WITH ALMOST ALL
TROPICAL SYSTEMS WHEN THEY MOVE INLAND. HANNA IS NO DIFFERENT. AS
HANNA WEAKENS...THE THREAT FOR TORNADOS WILL DECREASE. HOWEVER...THE
THREAT FOR HEAVY RAIN AND GUSTY WINDS WILL CONTINUE MOST OF THE
NIGHT.

.FOR SPOTTERS...
SPOTTER ACTIVATION IS NOT EXPECTED...BUT SPOTTERS SHOULD REMAIN
ALERT IN CASE NEEDED. EMERGENCY MANAGERS SHOULD MONITOR THE
SITUATION.

OTHER HAZARDS...
A PERIOD OF STRONG GUSTY WINDS WILL BE POSSIBLE AS THE REMNANTS
OF HANNA APPROACH AND MOVE ACROSS THE STATE TONIGHT.
