SITUATION OVERVIEW
------------------
AS OF 11 PM EDT, IDALIA HAS IS MOVING NORTHWARD AT 8 MPH AND MAXIMUM
SUSTAINED WINDS REMAIN NEAR 70 MPH, JUST BELOW HURRICANE STRENGTH.
IDALIA IS EXPECTED TO STRENGTHEN AND IS EXPECTED TO BECOME A MAJOR
HURRICANE ON TUESDAY OVER THE EASTERN GULF OF MEXICO. IDALIA IS
FORECAST TO MAKE LANDFALL EARLY WEDNESDAY ALONG THE NATURE COAST AS
A MAJOR HURRICANE.
THE POTENTIAL FOR LIFE-THREATENING STORM SURGE AROUND THE SHORES OF
APALACHEE BAY CONTINUES TO INCREASE. 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 TUESDAY AFTERNOON, WITH PEAK SURGE VALUES COMING ON TUESDAY
NIGHT 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.
IN ADDITION, THE ODDS OF HURRICANE FORCE WINDS ARE INCREASING OVER
THE SOUTHEAST BIG BEND. PROBABILITIES OF TROPICAL STORM FORCE WINDS
ACROSS THE BIG BEND AND SOUTH CENTRAL GEORGIA ALSO CONTINUE TO
INCREASE. PROBABILITIES FOR BOTH TROPICAL STORM AND HURRICANE FORCE
WINDS REMAIN NEARLY STEADY SINCE THE LAST ADVISORY. THE FORECAST
HURRICANE INTENSITY AT LANDFALL REMAINS THE SAME SINCE THE LAST
ADVISORY, WITH IDALIA EXPECTED TO BE A MAJOR HURRICANE AT LANDFALL.
A HURRICANE WARNING IS IN EFFECT FROM INDIAN PASS TO THE SUWANEE
RIVER, INCLUDING INLAND PORTIONS OF THE EASTERN FLORIDA BIG BEND. A
HURRICANE WATCH IS IN EFFECT FOR LEON AND INLAND WAKULLA COUNTIES. A
TROPICAL STORM WARNING IS IN EFFECT FROM MEXICO BEACH TO INDIAN
PASS, INCLUDING THE REMAINDER OF THE WESTERN FLORIDA BIG BEND.
MEANWHILE, TROPICAL STORM WARNINGS AND HURRICANE WARNINGS ARE IN
EFFECT FOR THE LOWER I-75 CORRIDOR OF GEORGIA.
TROPICAL STORM FORCE WINDS ARE MOST LIKELY TO ARRIVE ALONG THE COAST
ON TUESDAY EVENING, BUT THEY COULD ARRIVE AS EARLY AS TUESDAY
AFTERNOON. IT IS RECOMMENDED THAT PREPARATIONS FOR IDALIA BE
COMPLETED BEFORE SUNSET ON TUESDAY, IF NOT SOONER. EXPECT DOWNED
TREES AND POWERLINES, WITH PROLONGED POWER OUTAGES POSSIBLE.
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. THE STORM SHOULD
BE MOVING FAST ENOUGH TO PRECLUDE RIVER FLOODING AT THIS TIME.
ISOLATED TORNADOES ARE POSSIBLE AND LIFE-THREATENING RIP CURRENTS
WILL AFFECT BEACHES WELL AWAY FROM THE CORE OF THE STORM.
POTENTIAL IMPACTS
-----------------
* SURGE:
PROTECT AGAINST LIFE-THREATENING SURGE HAVING POSSIBLE DEVASTATING
IMPACTS ACROSS TAYLOR AND DIXIE COUNTIES. POTENTIAL IMPACTS IN
THIS AREA INCLUDE:
- WIDESPREAD DEEP INUNDATION, WITH STORM SURGE FLOODING GREATLY
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
ONSHORE AND STRANDED.
ALSO, PROTECT AGAINST LIFE-THREATENING SURGE HAVING POSSIBLE
SIGNIFICANT TO EXTENSIVE IMPACTS ACROSS WAKULLA AND JEFFERSON COUNTIES.
ALSO, PROTECT AGAINST LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED
IMPACTS ACROSS FRANKLIN COUNTY.
ELSEWHERE ACROSS EASTERN FLORIDA PANHANDLE AND SOUTHEASTERN ALABAMA, LITTLE TO NO IMPACT IS
ANTICIPATED.
* WIND:
PROTECT AGAINST LIFE-THREATENING WIND HAVING POSSIBLE DEVASTATING
IMPACTS ACROSS COASTAL AND SOUTHEAST FLORIDA BIG BEND. POTENTIAL IMPACTS IN
THIS AREA INCLUDE:
- STRUCTURAL DAMAGE TO STURDY BUILDINGS, SOME WITH COMPLETE ROOF
AND WALL FAILURES. COMPLETE DESTRUCTION OF MOBILE HOMES. DAMAGE
GREATLY ACCENTUATED BY LARGE AIRBORNE PROJECTILES. LOCATIONS
MAY BE UNINHABITABLE FOR WEEKS OR MONTHS.
- NUMEROUS LARGE TREES SNAPPED OR UPROOTED ALONG WITH FENCES AND
ROADWAY SIGNS BLOWN OVER.
- MANY ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
OR HEAVILY WOODED PLACES. MANY BRIDGES, CAUSEWAYS, AND ACCESS
ROUTES IMPASSABLE.
- WIDESPREAD POWER AND COMMUNICATIONS OUTAGES.
ALSO, PROTECT AGAINST LIFE-THREATENING WIND HAVING POSSIBLE LIMITED
TO EXTENSIVE IMPACTS ACROSS THE REMAINDER OF THE FLORIDA BIG BEND INTO THE LOWER I-75
CORRIDOR OF GEORGIA.
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS THE EASTERN FLORIDA BIG BEND AND THE I-75
CORRIDOR OF GEORGIA. POTENTIAL
IMPACTS INCLUDE:
- MAJOR RAINFALL FLOODING MAY PROMPT MANY EVACUATIONS AND RESCUES.
- RIVERS AND TRIBUTARIES MAY RAPIDLY OVERFLOW THEIR BANKS IN
MULTIPLE PLACES. SMALL STREAMS, CREEKS, AND DITCHES MAY BECOME
DANGEROUS RIVERS. FLOOD CONTROL SYSTEMS AND BARRIERS MAY BECOME
STRESSED.

COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. MANY PLACES WHERE FLOOD WATERS MAY COVER ESCAPE ROUTES.
STREETS AND PARKING LOTS BECOME RIVERS OF MOVING WATER WITH
UNDERPASSES SUBMERGED. DRIVING CONDITIONS BECOME DANGEROUS.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
LISTEN TO LOCAL OFFICIAL FOR RECOMMENDED PREPAREDNESS ACTIONS,
INCLUDING POSSIBLE EVACUATION. IF ORDERED TO EVACUATE, DO SO
IMMEDIATELY.
FOR THOSE NOT UNDER EVACUATION ORDERS, ASSESS THE RISK FROM WIND,
FALLING TREES, AND FLOODING AT YOUR LOCATION. IF YOU DECIDE TO MOVE,
RELOCATE TO A SAFER LOCATION NEARBY. IF YOU DO NOT RELOCATE, HELP KEEP
ROADWAYS OPEN FOR THOSE UNDER EVACUATION ORDERS.
IF EVACUATING, LEAVE WITH A DESTINATION IN MIND AND ALLOW EXTRA TIME
TO GET THERE. TAKE YOUR EMERGENCY SUPPLIES KIT. GAS UP YOUR VEHICLE
AHEAD OF TIME.
* OTHER PREPAREDNESS INFORMATION:
NOW IS THE TIME TO COMPLETE ALL PREPARATIONS TO PROTECT LIFE AND
PROPERTY IN ACCORDANCE WITH YOUR EMERGENCY PLAN. ENSURE YOU ARE IN A
SAFE LOCATION BEFORE THE ONSET OF STRONG WINDS OR POSSIBLE FLOODING.
IF YOU ARE RELOCATING TO SAFE SHELTER, LEAVE AS EARLY AS POSSIBLE.
ALLOW EXTRA TIME TO REACH YOUR DESTINATION. MANY ROADS AND BRIDGES
WILL BE CLOSED ONCE STRONG WINDS ARRIVE. CHECK THE LATEST WEATHER
FORECAST BEFORE DEPARTING AND DRIVE WITH CAUTION.
IF HEADING TO A COMMUNITY SHELTER, BECOME FAMILIAR WITH THE SHELTER
RULES BEFORE ARRIVAL, ESPECIALLY IF YOU HAVE SPECIAL NEEDS OR HAVE
PETS. TAKE ESSENTIAL ITEMS WITH YOU FROM YOUR EMERGENCY SUPPLIES KIT.
FAILURE TO ADEQUATELY SHELTER MAY RESULT IN SERIOUS INJURY OR LOSS OF
LIFE. ALWAYS HEED THE ADVICE OF LOCAL OFFICIALS AND COMPLY WITH ANY
ORDERS THAT ARE ISSUED. REMEMBER, DURING THE STORM 9 1 1 EMERGENCY
SERVICES MAY NOT BE ABLE TO IMMEDIATELY RESPOND IF CONDITIONS ARE
UNSAFE. THIS SHOULD BE A BIG FACTOR IN YOUR DECISION MAKING.
IF IN A PLACE THAT IS VULNERABLE TO HIGH WIND, SUCH AS NEAR LARGE
TREES, A MANUFACTURED HOME, UPPER FLOORS OF A HIGH-RISE BUILDING, OR ON
A BOAT, CONSIDER MOVING TO A SAFER SHELTER BEFORE THE ONSET OF STRONG
WINDS OR FLOODING.
