SITUATION OVERVIEW
------------------
HURRICANE IDALIA IS CONTINUING TO INTENSIFY AS IT MOVES NORTH AND
EVENTUALLY NORTHEAST ACROSS THE EASTERN GULF OF MEXICO THROUGH
WEDNESDAY. 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 LATE THIS AFTERNOON THROUGH EARLY THURSDAY. STORM SURGE
INUNDATION COULD REACH 10 TO 15 FEET ALONG THE LEVY COUNTY COASTLINE,
8 TO 12 ACROSS THE CITRUS COUNTY COASTLINE, 6 TO 9 FEET ALONG THE
HERNANDO AND PASCO COUNTY COASTLINES, 4 TO 7 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 START TO INCREASE THROUGH THE DAY TODAY, WITH
HURRICANE FORCE WINDS POSSIBLE ACROSS MUCH OF THE AREA, ESPECIALLY
NEAR THE COAST. IDALIA IS FORECAST TO INTENSIFY INTO A MAJOR
HURRICANE. TROPICAL STORM FORCE WINDS WILL BE POSSIBLE ACROSS THE
SOUTHERN ZONES. RUSH TO COMPLETION ANY PREPAREDNESS ACTIVITIES THIS
MORNING. DOWNED TREES AND POWERLINES, WITH PROLONGED POWER OUTAGES
WILL BE POSSIBLE.
* RAINFALL - RAIN BANDS FROM IDALIA WILL LIFT OVER THE AREA TODAY AS
THE STORM APPROACHES, WITH THE MORE CONSISTENT TROPICAL RAINS WITH THE
STORM POSSIBLE LATER TODAY THROUGH WEDNESDAY. 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:
PROTECT AGAINST LIFE-THREATENING SURGE HAVING POSSIBLE CATASTROPHIC
IMPACTS ACROSS LEVY COUNTY. 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 DEVASTATING IMPACTS ACROSS THE REST OF NATURE COAST AND
WEST CENTRAL FLORIDA.
ALSO, PROTECT AGAINST LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED
IMPACTS ACROSS SOUTHWEST FLORIDA.
* WIND:
PROTECT AGAINST LIFE-THREATENING WIND HAVING POSSIBLE DEVASTATING
IMPACTS ACROSS WEST CENTRAL AND SOUTHWEST FLORIDA. POTENTIAL IMPACTS
IN THIS AREA INCLUDE:
- STRUCTURAL DAMAGE TO STURDY BUILDINGS, SOME WITH COMPLETE ROOF

* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS WEST CENTRAL AND SOUTHWEST FLORIDA. 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, CANALS, AND DITCHES MAY
BECOME DANGEROUS RIVERS. FLOOD CONTROL SYSTEMS AND BARRIERS MAY
BECOME STRESSED.
- FLOOD WATERS CAN ENTER MANY STRUCTURES WITHIN MULTIPLE
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. MANY
ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED OR WASHED OUT.
* TORNADOES:
PROTECT AGAINST A DANGEROUS TORNADO EVENT HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS WEST CENTRAL AND SOUTHWEST FLORIDA. POTENTIAL 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

VEHICLES TUMBLED, AND BOATS TOSSED ABOUT. DANGEROUS PROJECTILES
CAN ADD TO THE TOLL.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
LET OTHERS KNOW WHERE YOU ARE GOING PRIOR TO DEPARTURE. SECURE LOOSE
ITEMS AND PETS IN THE CAR, AND AVOID DISTRACTED DRIVING.
IF EVACUATING, FOLLOW DESIGNATED EVACUATION ROUTES. SEEK TRAFFIC
INFORMATION ON ROADWAY SIGNS, THE RADIO, AND FROM OFFICIAL SOURCES.
DO NOT ENTER EVACUATED AREAS UNTIL OFFICIALS HAVE GIVEN THE ALL CLEAR
TO RETURN.
* OTHER PREPAREDNESS INFORMATION:
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.
KEEP CELL PHONES WELL CHARGED. CELL PHONE CHARGERS FOR AUTOMOBILES
CAN BE HELPFUL, BUT BE AWARE OF YOUR RISK FOR DEADLY CARBON MONOXIDE
POISONING IF YOUR CAR IS LEFT IDLING IN A GARAGE OR OTHER POORLY
VENTILATED AREA.
IT IS IMPORTANT TO REMAIN CALM, INFORMED, AND FOCUSED DURING AN
EMERGENCY. BE PATIENT AND HELPFUL WITH THOSE YOU ENCOUNTER.
STORM SURGE IS THE LEADING KILLER ASSOCIATED WITH TROPICAL STORMS AND
HURRICANES! MAKE SURE YOU ARE IN A SAFE AREA AWAY FROM THE SURGE
ZONE. EVEN IF YOU ARE NOT IN A SURGE-PRONE AREA, YOU COULD FIND
YOURSELF CUTOFF BY FLOOD WATERS DURING AND AFTER THE STORM. HEED
EVACUATION ORDERS ISSUED BY THE LOCAL AUTHORITIES.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO OR LOCAL NEWS OUTLETS
FOR OFFICIAL STORM INFORMATION. BE READY TO ADAPT TO POSSIBLE CHANGES
TO THE FORECAST. ENSURE YOU HAVE MULTIPLE WAYS TO RECEIVE WEATHER
WARNINGS.
