SITUATION OVERVIEW
------------------
AS OF 2PM EDT, THE CENTER OF HURRICANE IDALIA WAS MOVING NORTHEAST
THROUGH SOUTHEAST GEORGIA NEAR 20 MPH. MAX SUSTAINED WINDS ARE NOW
AROUND 75 MPH - CATEGORY ONE STRENGTH. IDALIA CONTINUES TO PRODUCE
AREAS OF TROPICAL STORM FORCE WINDS MOSTLY ALONG AND EAST OF THE I-
75 CORRIDOR WITH EMBEDDED HEAVY RAINFALL MAKING FOR A PERSISTING FLOOD
THREAT.
IMPACTS FROM STRONG WINDS AND HEAVY RAIN WILL CONTINUE UNTIL IDALIA
PULLS FARTHER AWAY FROM THE REGION LATER THIS AFTERNOON. THE THREAT
FOR DANGEROUS 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 5-8 FEET WITH 2-4 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.
ADJUSTMENTS WILL CONTINUE TO BE MADE AS CONDITIONS IMPROVE.
REGARDLESS, PLEASE CONTINUE TO HEED EVACUATION ORDERS AND ADVICE FROM
LOCAL OFFICIALS.
