SITUATION OVERVIEW
------------------
HURRICANE IDALIA CONTINUES TO INTENSIFY AS IT MOVES NORTH TO
NORTHEAST ACROSS THE EASTERN GULF OF MEXICO TODAY. CATASTROPHIC STORM
SURGE WILL ACCOMPANY THE STORM AS IT MAKES LANDFALL. WATCHES AND
WARNINGS REMAIN IN EFFECT FOR WEST CENTRAL AND SOUTHWEST FLORIDA AND
THE ADJACENT COASTAL WATERS.
THE FOLLOWING ARE THE PRIMARY HAZARDS OF CONCERN WITH IDALIA:
* STORM SURGE - AREAS ACROSS THE NORTHERN NATURE COAST COULD SEE
CATASTROPHIC LEVELS OF STORM SURGE, WITH LIFE-THREATENING SURGE ALSO
POSSIBLE ACROSS WEST-CENTRAL FLORIDA. THE MAIN PERIOD OF SURGE LOOKS
TO OCCUR THROUGH EARLY THURSDAY. STORM SURGE INUNDATION COULD REACH
12 TO 16 FEET ALONG THE LEVY COUNTY COASTLINE, 7 TO 11 ACROSS THE
CITRUS COUNTY COASTLINE, 6 TO 9 FEET ALONG THE HERNANDO AND PASCO
COUNTY COASTLINES, 4 TO 6 FEET FOR THE PINELLAS, HILLSBOROUGH, AND
MANATEE COUNTY COASTLINES, 3 TO 5 FEET ALONG THE SARASOTA COUNTY
COAST, AND 2 TO 4 FEET ALONG CHARLOTTE AND LEE COUNTIES.
* WIND - WINDS WILL CONTINUE TO INCREASE, WITH HURRICANE FORCE WINDS
POSSIBLE ACROSS MUCH OF THE AREA, ESPECIALLY NEAR THE COAST NORTH OF
TAMPA BAY. IDALIA HAS INTENSIFIED INTO A MAJOR HURRICANE. TROPICAL
STORM FORCE WINDS WILL CONTINUE ACROSS THE SOUTHERN ZONES. DOWNED
TREES AND POWERLINES, WITH PROLONGED POWER OUTAGES WILL BE POSSIBLE.
* RAINFALL - RAIN BANDS FROM IDALIA WILL CONTINUE TO LIFT OVER THE
AREA TODAY. A SLIGHT TO MODERATE RISK FOR FLOODING IS POSSIBLE, MAINLY
ALONG THE COAST AND ACROSS THE NORTHERN ZONES, CLOSER TO THE CENTER OF
THE STORM. RAINFALL TOTALS OF 4 TO 8 INCHES WITH LOCALLY HIGHER
AMOUNTS UP TO 12 INCHES IS POSSIBLE.
POTENTIAL IMPACTS
-----------------
* SURGE:
POTENTIAL IMPACTS FROM THE MAIN SURGE EVENT ARE NOW UNFOLDING ACROSS
WEST CENTRAL AND SOUTHWEST FLORIDA. REMAIN WELL AWAY FROM LIFE-THREATENING
SURGE HAVING POSSIBLE CATASTROPHIC IMPACTS. IF
REALIZED, THESE IMPACTS 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.
* WIND:
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE NOW UNFOLDING ACROSS
WEST CENTRAL AND SOUTHWEST FLORIDA. REMAIN WELL SHELTERED FROM
LIFE-THREATENING WIND HAVING POSSIBLEEXTENSIVE
IMPACTS. IF REALIZED, THESE IMPACTS INCLUDE:
- CONSIDERABLE ROOF DAMAGE TO STURDY BUILDINGS, WITH SOME HAVING
WINDOW, DOOR, AND GARAGE DOOR FAILURES LEADING TO STRUCTURAL
DAMAGE. MOBILE HOMES SEVERELY DAMAGED, WITH SOME DESTROYED.
DAMAGE ACCENTUATED BY AIRBORNE PROJECTILES. LOCATIONS MAY BE
UNINHABITABLE FOR WEEKS.
- MANY LARGE TREES SNAPPED OR UPROOTED ALONG WITH FENCES AND
ROADWAY SIGNS BLOWN OVER.
- SOME ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
OR HEAVILY WOODED PLACES. SEVERAL BRIDGES, CAUSEWAYS, AND
ACCESS ROUTES IMPASSABLE.
- LARGE AREAS WITH POWER AND COMMUNICATIONS OUTAGES.
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
WEST CENTRAL AND SOUTHWEST FLORIDA. REMAIN WELL GUARDED AGAINST DANGEROUS
FLOOD WATERS HAVING POSSIBLE SIGNIFICANT IMPACTS.
IF REALIZED, THESE IMPACTS INCLUDE:
- MODERATE RAINFALL FLOODING MAY PROMPT SEVERAL EVACUATIONS AND
RESCUES.
- RIVERS AND TRIBUTARIES MAY QUICKLY BECOME SWOLLEN WITH SWIFTER
CURRENTS AND OVERSPILL THEIR BANKS IN A FEW PLACES, ESPECIALLY
IN USUALLY VULNERABLE SPOTS. SMALL STREAMS, CREEKS, CANALS, AND
DITCHES OVERFLOW.
- FLOOD WATERS CAN ENTER SOME STRUCTURES OR WEAKEN FOUNDATIONS.
SEVERAL PLACES MAY EXPERIENCE EXPANDED AREAS OF RAPID
INUNDATION AT UNDERPASSES, LOW-LYING SPOTS, AND POOR DRAINAGE
AREAS. SOME STREETS AND PARKING LOTS TAKE ON MOVING WATER AS
STORM DRAINS AND RETENTION PONDS OVERFLOW. DRIVING CONDITIONS
BECOME HAZARDOUS. SOME ROAD AND BRIDGE CLOSURES.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS WEST CENTRAL AND SOUTHWEST FLORIDA.
REMAIN WELL BRACED AGAINST A DANGEROUS TORNADO
EVENT HAVING POSSIBLE SIGNIFICANT IMPACTS. IF
REALIZED, THESE IMPACTS INCLUDE:
- THE OCCURRENCE OF SCATTERED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- SEVERAL PLACES MAY EXPERIENCE TORNADO DAMAGE WITH A FEW SPOTS
OF CONSIDERABLE DAMAGE, POWER LOSS, AND COMMUNICATIONS FAILURES.
- LOCATIONS COULD REALIZE ROOFS TORN OFF FRAME HOUSES, MOBILE
HOMES DEMOLISHED, BOXCARS OVERTURNED, LARGE TREES SNAPPED OR
UPROOTED, VEHICLES TUMBLED, AND BOATS TOSSED ABOUT. DANGEROUS
PROJECTILES CAN ADD TO THE TOLL.
