SITUATION OVERVIEW
------------------
AS OF 11AM EDT, THE CENTER OF HURRICANE IDALIA WAS MOVING NORTH-
NORTHEAST THROUGH SOUTH-CENTRAL GEORGIA AT 20 MPH. MAX SUSTAINED WINDS ARE
NOW AROUND 90 MPH, WHICH IS CATEGORY ONE STRENGTH. IDALIA HAS PRODUCED
NUMEROUS MEASURED SUSTAINED TROPICAL-STORM FORCE WINDS WITH OCCASIONAL
GUSTS TO HURRICANE FORCE (ESPECIALLY TAYLOR, DIXIE, LAFAYETTE, MADISON
COUNTIES) MAINLY ALONG AND EAST OF ITS TRACK. IN ADDITION, HEAVY
RAINFALL HAS BEEN OBSERVED CLOSE TO IDALIA'S CORE, WHICH HAS PRODUCED
INSTANCES OF FLASH FLOODING EXTENDING FROM THE SOUTHEAST FLORIDA BIG
BEND NEAR PERRY IN TO THE I-75 CORRIDOR. THE VALDOSTA AREA IS
CURRENTLY EXPERIENCING A FLASH FLOOD EMERGENCY WITH MULTIPLE WATER
RESCUES AND EVACUATIONS REPORTED. GUSTS IN EXCESS OF 40 MPH
(OCCASIONALLY 50+ MPH) HAVE ALSO BEEN OBSERVED IN THE TALLAHASSEE
AREA. WIDESPREAD WIND DAMAGE HAS BEEN REPORTED IN THE EASTERN PORTIONS
OF THE AREA AND SIGNIFICANT SURGE ALONG THE COASTAL BIG BEND.
IMPACTS FROM STRONG WINDS AND HEAVY RAIN, IN ADDITION TO THE
POSSIBILITY OF TORNADOES WILL CONTINUE UNTIL IDALIA PULLS AWAY FROM
THE REGION LATER THIS AFTERNOON. THE THREAT FOR LIFE-THREATENING STORM
SURGE ALSO REMAINS IN PLACE FOR THE NATURE COAST WHERE A STORM SURGE
WARNING REMAINS IN EFFECT. FROM KEATON BEACH TO SUWANNEE RIVER,
FORECAST VALUES ARE 7-11 FEET WITH 3-5 FEET FORECAST FROM AUCILLA
RIVER TO KEATON BEACH. ALTHOUGH WATER LEVELS MAY BE SUBSIDING A BIT
NOW, ONSHORE FLOW FROM THE SOUTH SIDE OF IDALIA ALONG WITH HIGH TIDE
THIS AFTERNOON COULD CAUSE ANOTHER PEAK IN STORM SURGE. MEANWHILE,
TROPICAL STORM WARNINGS WERE CANCELLED FOR GULF COUNTY. ALL OTHER
ACTIVE WARNINGS ARE UNCHANGED FROM THE PREVIOUS ADVISORY.
ALTHOUGH CONDITIONS WILL GRADUALLY IMPROVE THIS AFTERNOON, PLEASE
CONTINUE TO HEED EVACUATION ORDERS AND ADVICE FROM LOCAL OFFICIALS.

ACCENTUATED BY POWERFUL BATTERING WAVES. STRUCTURAL DAMAGE TO
BUILDINGS, WITH MANY WASHING AWAY. DAMAGE GREATLY COMPOUNDED
FROM CONSIDERABLE FLOATING DEBRIS. LOCATIONS MAY BE
UNINHABITABLE FOR AN EXTENDED PERIOD.
- NEAR-SHORE ESCAPE ROUTES AND SECONDARY ROADS WASHED OUT OR
SEVERELY FLOODED. FLOOD CONTROL SYSTEMS AND BARRIERS MAY BECOME
STRESSED.
- EXTREME BEACH EROSION. NEW SHORELINE CUTS POSSIBLE.
- MASSIVE DAMAGE TO MARINAS, DOCKS, BOARDWALKS, AND PIERS.
NUMEROUS SMALL CRAFT BROKEN AWAY FROM MOORINGS WITH MANY LIFTED

COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. MANY PLACES WHERE FLOOD WATERS MAY COVER ESCAPE ROUTES.

QUICKLY MOVE TO THE SAFEST PLACE WITHIN YOUR SHELTER IF IT BEGINS TO
FAIL, PREFERABLY AN INTERIOR ROOM ON THE LOWEST FLOOR AS LONG AS

IF YOU ARE PRONE TO FLOODING OR IN AN AREA UNDER A STORM SURGE WATCH
OR WARNING, BE PREPARED FOR THE POSSIBILITY OF A QUICK AND DRAMATIC
RISE IN WATER LEVELS.
