...TWO MORE ROUNDS OF HEAVY RAIN AND FLOODING LIKELY EARLY FRIDAY
THROUGH TUESDAY...

.RAINFALL EXPECTED...
THE FIRST ROUND OF HEAVY RAIN WILL OCCUR EARLY FRIDAY THROUGH
SATURDAY OVER PORTIONS OF NORTH GEORGIA AND ALL OF CENTRAL GEORGIA.
THE AREA OF CONCERN WILL BE MAINLY SOUTH OF A LINE FROM ROME TO
CUMMING TO HOMER. RAINFALL AMOUNTS OF 1 TO 2 INCHES CAN BE

A SECOND ROUND OF HEAVY RAIN SHOULD MAINLY AFFECT CENTRAL GEORGIA
MONDAY AND MONDAY NIGHT WITH AN ADDITIONAL 2 INCHES OF RAIN.
ANOTHER INCH OF RAIN IS POSSIBLE OVER NORTH GEORGIA.

THE COMBINED RAINFALL PROJECTIONS FOR BOTH HEAVY RAIN EVENTS ARE
FROM 1 TO 3 INCHES OVER NORTH GEORGIA TO 4 TO 6 INCHES OVER
CENTRAL GEORGIA. LOCALLY HIGHER AMOUNTS WILL BE POSSIBLE.

.SYNOPSIS...
A STORM SYSTEM IS EXPECTED TO DEVELOP OVER THE SOUTHERN PLAINS ON
THURSDAY AND MOVE INTO THE MIDWEST FRIDAY. LOW LEVEL WINDS AHEAD
OF THE ASSOCIATED WARM AND COLD FRONTS WILL BRING VERY MOIST GULF
AIR INTO GEORGIA. WIDESPREAD RAIN WITH EMBEDDED CONVECTION IS
EXPECTED EARLY FRIDAY THROUGH SATURDAY. ANOTHER STORM SYSTEM IN
THE CENTRAL PLAINS ON MONDAY WILL CONTINUE TO DRAW GULF MOISTURE
INTO THE STATE WITH PERIODS OF HEAVY RAIN...MAINLY OVER CENTRAL
AND SOUTH GEORGIA ON MONDAY ENDING BY TUESDAY MORNING.

.PRE-EXISTING CONDITIONS...
SINCE THE BEGINNING OF FEBRUARY...2 TO 4 INCHES OF RAIN HAS
OCCURRED OVER NORTH GEORGIA AND 4 TO 8 INCHES FELL OVER CENTRAL
GEORGIA. ACCORDINGLY...THESE MOIST TO WET SOIL CONDITIONS WILL
ALLOW ANY HEAVY RAIN TO QUICKLY RUN OFF INTO NEARBY STREAMS...
CREEKS AND RIVERS. THE LOWER OCMULGEE RIVER NEAR ABBEVILLE
CONTINUES IN MINOR FLOOD FROM LAST WEEKS RAIN.

AREAS OF FLASH FLOODING WILL BE POSSIBLE IF THE HEAVY RAIN
REPEATEDLY MOVES OVER THE SAME AREA. ALSO...STORM DRAINS...DITCHES
...AND LOW LYING AREAS MAY BECOME QUICKLY CLOGGED WITH DEBRIS AND
CAUSE EXTENSIVE STREET FLOODING.

WIDESPREAD MINOR FLOODING OF THE LARGER CREEKS OR RIVERS IS MOST
LIKELY TO DEVELOP WITH THE EXPECTED STORM TOTAL RAINFALL AMOUNTS.
HOWEVER...DUE TO THE PRE-EXISTING CONDITIONS...ISOLATED SIGNIFICANT
FLOODING MAY AFFECT FLOOD PRONE ROADS AND STRUCTURES NEARBY.
