...HEAVY RAIN AND FLOODING LIKELY THIS WEEKEND OVER NORTH AND
WEST CENTRAL GEORGIA...
.RAINFALL EXPECTED...
PERIODS OF RAIN WILL DEVELOP OVER NORTH AND CENTRAL GEORGIA ON
FRIDAY NIGHT AND BECOME WIDESPREAD OVER THE STATE SATURDAY THROUGH
MONDAY. STORM TOTAL RAINFALL AMOUNTS OF 2 TO 3 INCHES WITH
ISOLATED HIGHER AMOUNTS CAN BE EXPECTED OVER NORTH AND PORTIONS OF
WEST CENTRAL GEORGIA THIS WEEKEND. THE MAIN AREA OF CONCERN WILL BE
MAINLY NORTH OF A LINE FROM NEAR LAGRANGE THROUGH FAYETTEVILLE AND
COVINGTON TO COMER. RAINFALL AMOUNTS OF 1 TO 1.5 INCHES ARE
EXPECTED OVER THE REMAINDER OF CENTRAL GEORGIA.
.SYNOPSIS...
A STRONG STORM SYSTEM MOVING THROUGH THE CENTRAL U.S. WILL DEEPEN
AS IT MOVES EAST THIS WEEKEND. LOW LEVEL WINDS AHEAD OF THE
ASSOCIATED WARM AND COLD FRONTS WILL PUMP VERY MOIST ATLANTIC AND
GULF MOISTURE INTO GEORGIA. WIDESPREAD RAIN WITH EMBEDDED
THUNDERSTORMS ARE EXPECTED TO DEVELOP FRIDAY NIGHT AND SPREAD OVER
THE STATE THROUGH MONDAY.
.PRE-EXISTING CONDITIONS...
DURING THE PAST 7 DAYS RAINFALL AMOUNTS OF 2 TO 5 INCHES OCCURRED
OVER NORTH GEORGIA AND 1.5 TO 2.5 INCHES OVER PORTIONS OF WEST
CENTRAL GEORGIA. ACCORDINGLY...THESE MOIST TO WET SOIL CONDITIONS
WILL ALLOW ANY HEAVY RAIN TO QUICKLY RUN OFF INTO NEARBY STREAMS...
CREEKS AND RIVERS. SEVERAL MAINSTEM CREEKS AND RIVERS IN NORTHWEST
GEORGIA HAD MINOR FLOODING EARLIER THIS WEEK AND HAVE JUST GONE
BELOW FLOOD STAGE. MOST STREAM AND RIVER LEVELS ARE FLOWING ABOVE
NORMAL.
.IMPACTS...
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. THIS WILL BE POSSIBLE MAINLY IN NORTHWEST GEORGIA ON
CREEKS AND RIVERS THAT WERE IN FLOOD EARLIER THIS WEEK.
THIS HAZARDOUS WEATHER EVENT WILL BECOME MORE CERTAIN AS UPDATED
INFORMATION BECOMES AVAILABLE. STAY ADVISED ON THIS SITUATION AND
KNOW WHAT TO DO IF A WARNING IS ISSUED.
