HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
642 AM EDT SUN APR 27 2014

...HEAVY RAIN EXPECTED OVER NORTH AND CENTRAL GEORGIA MONDAY NIGHT
THROUGH WEDNESDAY NIGHT WITH POSSIBLE FLOODING...

.RAINFALL EXPECTED...
STORM TOTAL RAINFALL AMOUNTS OF 2 TO 4 INCHES ARE FORECAST FOR
NORTH GEORGIA MONDAY THROUGH WEDNESDAY NIGHT. ISOLATED HIGHER 
AMOUNTS POSSIBLE. THIS INCLUDES THE ATLANTA METRO AREA. AROUND 1
TO 2 INCHES ARE EXPECTED FOR CENTRAL GEORGIA MONDAY NIGHT THROUGH
THURSDAY.

.SYNOPSIS...
A STRONG LOW PRESSURE SYSTEM AND ITS ASSOCIATED COLD FRONT OVER
THE CENTRAL AND SOUTHERN PLAINS WILL MOVE SLOWLY TOWARD GEORGIA
THROUGH TUESDAY. THE FRONT WILL PASS OVER THE STATE ON WEDNESDAY.
A STRONG LOW LEVEL JET WILL PROVIDE ABUNDANT GULF MOISTURE IN
ADVANCE OF THE STORM WHICH WILL COMBINE WITH THE OROGRAPHIC
EFFECTS OF THE GEORGIA MOUNTAINS TO ENHANCE THE RAINFALL.

.PRE-EXISTING CONDITIONS...
RAINFALL AMOUNTS OF 2 TO 4 INCHES HAVE OCCURRED OVER CENTRAL GEORGIA
DURING THE PAST TWO WEEKS WHICH WERE 150 TO 300 PERCENT OF
NORMAL. CONSEQUENTLY...MOIST SOIL CONDITIONS EXIST WITH SOME AREAS
STILL WET AND JUST RECOVERING FROM WELL ABOVE NORMAL STREAMFLOWS
AND FLOODING. THIS WILL ALLOW ANY HEAVY RAIN TO BE QUICKLY
ABSORBED...THEN RUN OFF INTO NEARBY STREAMS...CREEKS AND RIVERS.

WHILE SOME AREAS OF EXTREME NORTH GEORGIA HAVE HAD BELOW NORMAL
RAINFALL FOR THE PAST FEW MONTHS...THE HEAVY RAINFALL AMOUNTS 
EXPECTED WITH THIS STORM SYSTEM WILL QUICKLY SATURATE THE SOILS
AND PRODUCE RAPID RUNOFF INTO NEARBY STREAMS...CREEKS AND RIVERS.

.IMPACTS...
ISOLATED FLASH FLOODING WILL BE POSSIBLE IF THE HEAVY RAIN 
REPEATEDLY MOVES OVER THE SAME AREA. ALSO...STORM DRAINS AND DITCHES 
MAY BECOME QUICKLY CLOGGED WITH DEBRIS AND CAUSE EXTENSIVE STREET 
FLOODING AND ROAD PONDING.

MINOR FLOODING OF SOME OF THE LARGER CREEKS OR RIVERS IS MORE LIKELY 
WITH THE EXPECTED STORM TOTAL RAINFALL AMOUNTS IN NORTH AND CENTRAL
GEORGIA AND SHOULD BE MONITORED CLOSELY.

THIS WEATHER SITUATION IS BECOMING MORE CERTAIN WITH EACH MODEL
RUN...SO STAY ALERT FOR POSSIBLE FLOOD WATCHES AND FUTURE WARNINGS.
KNOW WHAT TO DO IF A WARNING IS ISSUED AND YOU LIVE NEAR A CREEK
OR RIVER.
