SITUATION OVERVIEW
------------------
AS OF 11 AM ET, HURRICANE ISAIAS WAS LOCATED IN THE NORTHERN GULF WITH
MAXIMUM SUSTAINED WINDS OF 120 MPH, MOVING NNE AT 16 MPH. ISAIAS IS
FORECAST TO ACCELERATE TOWARDS THE NORTHERN GULF COAST THIS EVENING
INTO EARLY SATURDAY, AND BEGIN BRINGING WIDESPREAD AND POTENTIALLY
SIGNIFICANT IMPACTS TO NORTH AND CENTRAL GEORGIA. THESE INCLUDE A
PROLONGED PERIOD OF STRONG WINDS, HEAVY RAINFALL WITH LOCALIZED
FLOODING, AND THE POTENTIAL FOR SEVERAL TORNADOES. IMPACTS WILL PEAK
IN INTENSITY SATURDAY INTO SATURDAY NIGHT AS ISAIAS MOVES NORTHWARD
ACROSS MISSISSIPPI/ALABAMA AND INTO THE TENNESSEE VALLEY.
THE WIND FIELD ASSOCIATED WITH ISAIAS IS EXPECTED TO EXPAND
CONSIDERABLY AS THE SYSTEM MOVES INLAND AND BECOMES EXTRA-TROPICAL.
STRONG WINDS WILL EXTEND WELL EAST OF THE CENTER OF THE STORM AND INTO
WEST-CENTRAL GEORGIA. A TROPICAL STORM WARNING IS NOW IN EFFECT FOR
THIS AREA WHERE WIND GUSTS TO 50 MPH WILL BE POSSIBLE. FURTHER NORTH
AND EAST, WHILE ISAIAS WILL BE WEAKENING AND BECOMING POST- TROPICAL,
THERE WILL BE A VERY STRONG PRESSURE GRADIENT BETWEEN THE SYSTEM AND
STRONG HIGH PRESSURE OVER THE MID-ATLANTIC. THIS GRADIENT WILL SUPPORT
A PROLONGED PERIOD OF STRONG EASTERLY WINDS WITH FREQUENT GUSTS TO
40 TO 50 MPH ACROSS MOST OF NORTH GEORGIA FROM TONIGHT THROUGH EARLY
SUNDAY. A HIGH WIND WARNING HAS BEEN ISSUED FOR THIS AREA. AREAS TO
THE SOUTH AND EAST OF THESE WARNINGS HAVE BEEN PLACED IN A WIND
ADVISORY WHERE WINDS WILL BE WEAKER, BUT STILL HAVE GUSTS TO 40 MPH.
ACROSS ALL AREAS, THE PROLONGED AND STRONG WINDS COULD LEAD TO POWER
OUTAGES FROM DOWNED LIMBS AND TREES, ESPECIALLY WHEN COMBINED WITH
SATURATED SOILS FROM PERIODS OF HEAVY RAIN.
ISAIAS WILL BRING WIDESPREAD RAINFALL, WITH MULTIPLE BANDS OF HEAVY
RAIN EXPECTED TONIGHT THROUGH EARLY SUNDAY. WIDESPREAD RAINFALL TOTALS
OF 1 TO 4 INCHES ARE LIKELY ACROSS MUCH OF THE AREA, WITH A LOCALIZED
SWATH OF UP TO 8 INCHES WHERE THE HEAVIEST BANDING SETS UP. THIS
RAINFALL COULD LEAD TO LOCALIZED FLASH FLOODING, PARTICULARLY IN URBAN
AND POOR-DRAINGE AREAS, AS WELL AS FLOOD-PRONE CREEKS AND STREAMS. A
FLOOD WATCH HAS BEEN ISSUED FOR THE ENTIRE AREA.
ADDITIONALLY, AS ISAIAS TRACKS NORTHWARD AND INLAND LATE TONIGHT INTO
SATURDAY, A FAVORABLE ENVIRONMENT FOR TORNADOES WILL DEVELOP ACROSS
NORTH AND CENTRAL GEORGIA, AND CONTINUE THROUGH SATURDAY NIGHT.
SEVERAL TORNADOES WILL BE POSSIBLE, PARTICULARLY WITHIN THE OUTER
RAINBANDS OF THE SYSTEM. TORNADOES FROM TROPICAL SYSTEMS ARE TYPICALLY
QUICK TO DEVELOP AND SHORT-LIVED, BUT WITH THE FORWARD SPEED OF THE
SYSTEM AND THE UNIQUE SETUP, WE CAN'T RULE OUT A STRONGER (EF2 OR
EF3), LONG-TRACK TORNADO, ESPECIALLY ACROSS CENTRAL GEORGIA.
