HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
308 PM EDT MON APR 13 2015

...OCCASIONAL HEAVY RAIN EXPECTED OVER PORTIONS OF NORTH AND
CENTRAL GEORGIA THROUGH MUCH OF THIS WEEK WITH POSSIBLE
FLOODING...

.RAINFALL EXPECTED...
STORM TOTAL RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE POSSIBLE FOR
PORTIONS OF NORTH AND CENTRAL GEORGIA THROUGH THURSDAY. LOCALLY
HIGHER AMOUNTS CAN BE EXPECTED. PERIODS OF HEAVY RAIN WILL RESULT
IN SATURATED GROUND CONDITIONS WHICH WILL INCREASE THE FLOOD
THREAT THROUGHOUT THE WEEK.

.SYNOPSIS...
AN UNSEASONABLY MOIST AND UNSETTLED PATTERN WILL SET UP ACROSS THE
SOUTHEAST REGION THIS WEEK. A SERIES OF UPPER LEVEL LOW PRESSURE
SYSTEMS WILL PRODUCE PERIODS OF MODERATE TO HEAVY RAINFALL ACROSS
NORTH AND CENTRAL GEORGIA THROUGH THURSDAY. RAINFALL AMOUNTS COULD
BE ENHANCED ALONG A FRONTAL BOUNDARY MOVING ACROSS NORTH GEORGIA
LATE TONIGHT INTO TUESDAY MORNING. A SECONDARY COLD FRONT COULD
ENHANCE RAINFALL ACROSS THE AREA AGAIN WEDNESDAY NIGHT INTO
THURSDAY.

.ANTECEDENT CONDITIONS...
RAINFALL AMOUNTS OF 2 TO 3 INCHES HAVE OCCURRED OVER NORTH AND
PARTS OF CENTRAL GEORGIA DURING THE PAST WEEK WHICH IS 100 TO 150
PERCENT OF NORMAL VALUES. ABNORMALLY MOIST SOIL CONDITIONS
CONTINUE TO EXIST WITH MOST AREAS STILL WET AND APPROACHING 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.
