------------------
AS OF 5 AM EDT, IDALIA HAS BECOME A HURRICANE WITH MAXIMUM SUSTAINED
WINDS OF 75 MPH. IDALIA IS CENTERED ABOUT 460 MILES SOUTH OF
STEINHATCHEE, FLORIDA, MOVING NORTH AT 14 MPH. IDALIA WILL RAPIDLY
INTENSIFY TODAY AND WILL SLAM INTO THE FLORIDA BIG BEND WEDNESDAY
MORNING AS A MAJOR HURRICANE. STRENGTHENING IS POSSIBLE ALL THE WAY
UP TO LANDFALL. TO PUT THIS INTO HISTORICAL CONTEXT, THERE ARE NO
MAJOR HURRICANES IN THE HISTORICAL DATASET GOING BACK TO 1851 THAT
HAVE TRACKED INTO APALACHEE BAY. THIS HAS THE MAKINGS OF AN
UNPRECEDENTED EVENT FOR THIS PART OF THE STATE.
YOUR FINAL PREPARATIONS NEED TO BE FINISHED BEFORE SUNSET THIS
EVENING. IF YOU HAVE BEEN ORDERED TO EVACUATE, LEAVE TODAY BEFORE
SUNSET. CONDITIONS WILL RAPIDLY DETERIORATE TONIGHT AND INTO THE DAY
WEDNESDAY.
LIFE-THREATENING STORM SURGE IS EXPECTED AROUND THE SHORES OF
APALACHEE BAY. STORM SURGE WILL BE HIGHLY DEPENDENT ON THE STORM
TRACK, WITH THE HIGHEST SURGE VALUES ALONG AND TO THE RIGHT OF THE
CENTER. STORM SURGE COULD START TO BUILD AS SOON AS THIS AFTERNOON,
WITH PEAK SURGE VALUES COMING ON TONIGHT AND WEDNESDAY.
A STORM SURGE WARNING IS IN EFFECT FROM INDIAN PASS TO THE SUWANEE
RIVER FOR THE DANGER OF LIFE THREATENING INUNDATION FROM RISING
WATER MOVING INLAND. STORM SURGE INUNDATION ABOVE NORMALLY DRY
GROUND COULD REACH THE FOLLOWING HEIGHTS, IF THE PEAK SURGE OCCURS
WITH HIGH TIDE: 1 TO 3 FEET FROM MEXICO BEACH TO INDIAN PASS, 3 TO 5
FEET FROM INDIAN PASS TO THE OCHLOCKONEE RIVER, 5 TO 8 FEET FROM THE
OCHLOCKONEE RIVER TO THE AUCILLA RIVER, AND 8 TO 12 FEET FROM THE
AUCILLA RIVER TO THE SUWANNEE RIVER. THE DEEPEST WATER WILL OCCUR
ALONG THE IMMEDIATE COAST, WHERE THE SURGE WILL BE ACCOMPANIED BY
LARGE AND DANGEROUS WAVES.
HURRICANE CONDITIONS ARE LIKELY IN THE EASTERN FLORIDA BIG BEND.
RESIDENTS IN THE SOUTHEAST BIG BEND NEED TO PREPARE FOR A MAJOR
HURRICANE WITH SUSTAINED WINDS OVER 110 MPH. A HURRICANE WARNING IS
IN EFFECT FROM INDIAN PASS TO THE SUWANEE RIVER, INCLUDING INLAND
PORTIONS OF THE EASTERN FLORIDA BIG BEND AND LOWER I-75 CORRIDOR OF
GEORGIA. A HURRICANE WATCH IS IN EFFECT FOR LEON AND INLAND WAKULLA
COUNTIES. THIS WATCH IS IN EFFECT TO ACCOUNT FOR ANY POSSIBLE
WESTWARD SHIFTS TO THE FORECAST TRACK. A TROPICAL STORM WARNING IS
IN EFFECT FROM MEXICO BEACH TO INDIAN PASS, INCLUDING THE REMAINDER
OF THE WESTERN FLORIDA BIG BEND AS WELL AS PARTS OF SOUTH CENTRAL
GEORGIA AND THE I-75 CORRIDOR.
TROPICAL STORM FORCE WINDS ARE MOST LIKELY TO ARRIVE ALONG THE COAST
AFTER MIDNIGHT TONIGHT, BUT THEY COULD ARRIVE AS EARLY AS THIS
EVENING. PREPARATIONS FOR IDALIA NEED TO BE COMPLETED BEFORE SUNSET.
EXPECT DOWNED TREES AND POWERLINES, POSSIBLY WIDESPREAD IN THE
EASTERN BIG BEND, WITH PROLONGED POWER OUTAGES POSSIBLE. ENSURE YOU
HAVE ENOUGH SUPPLIES TO LAST FOR SEVERAL DAYS.
RAINFALL AMOUNTS WILL BE HEAVIEST ALONG AND EAST OF THE TRACK OF
IDALIA, ESPECIALLY IN THE EASTERN FLORIDA BIG BEND, WHERE 5 TO 8
INCHES OF RAIN ARE FORECAST, WITH ISOLATED HIGHER AMOUNTS POSSIBLE.
THIS COULD LEAD TO LIFE THREATENING FLASH FLOODING. A FLOOD WATCH IS
NOW IN EFFECT FROM GULF COUNTY, FL TO LEE COUNTY, GA AND ALL POINTS
EASTWARD. THE STORM SHOULD BE MOVING FAST ENOUGH TO PRECLUDE
WIDESPREAD RIVER FLOODING AT THIS TIME.
SEVERAL TORNADOES ARE POSSIBLE IN THE OUTER RAIN BANDS STARTING
TONIGHT AND CONTINUING INTO WEDNESDAY. THIS WILL PRIMARILY BE NORTH
AND EAST OF THE CENTER.
LIFE-THREATENING RIP CURRENTS AND HIGH SURF ARE EXPECTED ALONG ALL
BEACHES FOR AT LEAST THE NEXT COUPLE DAYS. EVERYONE NEEDS TO STAY
OUT OF THE WATER.
