HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
940 AM EDT TUE MAR 10 2015

...OCCASIONAL HEAVY RAIN EXPECTED OVER PORTIONS OF NORTH GEORGIA
THROUGH SATURDAY WITH POSSIBLE FLOODING...

.RAINFALL EXPECTED...
STORM TOTAL RAINFALL AMOUNTS OF 2 TO 4 INCHES ARE FORECAST FOR
NORTH GEORGIA THROUGH SATURDAY. ISOLATED HIGHER AMOUNTS ARE
POSSIBLE. THE GREATEST FLOOD POTENTIAL AREA AT THIS TIME IS
GENERALLY NORTH OF A LINE FROM ROME THROUGH CUMMING TO HOMER.

.SYNOPSIS...
A STRONG UPPER LEVEL LOW PRESSURE SYSTEM WILL DEEPEN AND ANCHOR
ITSELF OVER THE SOUTHERN PLAINS THIS WEEK. A STRONG SOUTH TO
SOUTHWEST FLOW ALOFT WILL PUMP ABUNDANT GULF MOISTURE OVER THE
SOUTHEAST U.S. WITH PERIODS OF HEAVY RAIN PREVAILING OVER NORTH
GEORGIA. AT THIS TIME...SOME OF THE HEAVIEST RAIN IS EXPECTED
THURSDAY THROUGH SATURDAY AS A SOUTHERLY LOW LEVEL FLOW COMBINES
WITH THE OROGRAPHIC EFFECTS OF THE GEORGIA MOUNTAINS TO ENHANCE
THE RAINFALL.

.ANTECEDENT CONDITIONS...
PRECIPITATION AMOUNTS OF 2 TO 3 INCHES HAVE OCCURRED OVER NORTH
GEORGIA DURING THE PAST TWO WEEKS WHICH WERE 50 TO 100 PERCENT OF
NORMAL. HOWEVER...DUE TO A SERIES OF SNOW AND ICE STORMS SINCE
THE MIDDLE OF FEBRUARY...ABNORMALLY MOIST SOIL CONDITIONS EXIST
WITH SOME AREAS STILL WET AND JUST RECOVERING FROM ABOVE NORMAL
STREAM FLOWS. THIS WILL ALLOW ANY HEAVY RAIN TO BE QUICKLY
ABSORBED...THEN RUN OFF 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
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.
