SITUATION OVERVIEW
------------------
TROPICAL STORM IDALIA CONTINUES TO STRENGTHEN IN THE YUCATAN CHANNEL
TODAY. THE STORM IS FORECAST TO MOVE INTO THE SOUTHEAST GULF OF
MEXICO TONIGHT INTO TUESDAY. IDALIA IS FORECAST TO KEEP
STRENGTHENING OVER THE EASTERN GULF AS IT MOVES CLOSER TO THE WEST
COAST OF FLORIDA.
THE FOLLOWING ARE THE PRIMARY HAZARDS OF CONCERN WITH IDALIA:
* COASTAL FLOODING/SURGE - HIGHER THAN USUAL TIDES DUE TO THE
COMBINATION OF SURGE FROM IDALIA AND THE FULL MOON COULD LEAD TO
COASTAL FLOODING OF 2 TO 4 FEET IN COASTAL COLLIER COUNTY AND 1 TO
3 FEET ALONG THE COAST OF MAINLAND MONROE COUNTY. OTHER VULNERABLE
COASTAL AREAS OF SOUTHERN FLORIDA COULD ALSO EXPERIENCE MINOR
COASTAL FLOODING, ESPECIALLY AROUND THE TIMES OF HIGH TIDE.
* RAINFALL - THE MAJORITY OF THE RAINFALL ASSOCIATED WITH THE SYSTEM
IS FORECAST TO FALL FROM THIS AFTERNOON THROUGH WEDNESDAY. THE
GREATEST RISK FOR FLASH FLOODING WILL BE NEAR THE GULF COAST.
STORM TOTAL RAIN AMOUNTS OF 2 TO 3 INCHES WITH LOCALIZED HIGHER
AMOUNTS. THE HIGHEST AMOUNTS ARE ANTICIPATED ALONG THE GULF COAST.
* WIND - INCREASINGLY GUSTY WINDS ARE FORECAST TUESDAY THROUGH
THURSDAY, PARTICULARLY ALONG THE GULF COAST AND ADJACENT COASTAL
WATERS. A REASONABLE WORST CASE SCENARIO WOULD HAVE TROPICAL STORM
FORCE WINDS ACROSS COLLIER COUNTY BETWEEN MONDAY NIGHT AND
WEDNESDAY. AREAS OF THE EAST COAST AND ATLANTIC WATERS COULD ALSO
SEE GUSTY WINDS UP TO 35 MPH DURING THE SAME TIME FRAME.
* TORNADOES - A LOW-END TORNADO THREAT IS POSSIBLE THROUGH EARLY
THURSDAY AS BANDING FROM THE SYSTEM MOVES ASHORE. THE FOCUS FOR
TORNADIC ACTIVITY COULD BE IN THE WESTERN HALF OF SOUTHERN
FLORIDA.
POTENTIAL IMPACTS
-----------------
* SURGE:
PROTECT AGAINST LIFE-THREATENING SURGE HAVING POSSIBLE SIGNIFICANT
IMPACTS ACROSS COASTAL COLLIER COUNTY. POTENTIAL IMPACTS IN
THIS AREA INCLUDE:
- AREAS OF INUNDATION WITH STORM SURGE FLOODING ACCENTUATED BY
WAVES. DAMAGE TO SEVERAL BUILDINGS, MAINLY NEAR THE COAST.
- SECTIONS OF NEAR-SHORE ESCAPE ROUTES AND SECONDARY ROADS BECOME
WEAKENED OR WASHED OUT, ESPECIALLY IN USUALLY VULNERABLE LOW
SPOTS.
- MAJOR BEACH EROSION WITH HEAVY SURF BREACHING DUNES. STRONG AND
NUMEROUS RIP CURRENTS.
- MODERATE DAMAGE TO MARINAS, DOCKS, BOARDWALKS, AND PIERS.
SEVERAL SMALL CRAFT BROKEN AWAY FROM MOORINGS, ESPECIALLY IN
UNPROTECTED ANCHORAGES.
ALSO, PROTECT AGAINST LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED
IMPACTS ACROSS COASTAL PORTIONS OF MAINLAND MONROE COUNTY.
ELSEWHERE ACROSS SOUTH FLORIDA, LITTLE TO NO IMPACT IS ANTICIPATED.

- FLOOD WATERS CAN ENTER A FEW STRUCTURES, ESPECIALLY IN USUALLY
VULNERABLE SPOTS. A FEW PLACES WHERE RAPID PONDING OF WATER
OCCURS AT UNDERPASSES, LOW-LYING SPOTS, AND POOR DRAINAGE
AREAS. SEVERAL STORM DRAINS AND RETENTION PONDS BECOME
NEAR-FULL AND BEGIN TO OVERFLOW. SOME BRIEF ROAD AND BRIDGE
CLOSURES.
* TORNADOES:
PROTECT AGAINST A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS
ACROSS SOUTH FLORIDA. POTENTIAL IMPACTS INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, MOBILE
HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED, LARGE TREE TOPS AND

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.
* 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.
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.
IF YOU ARE A VISITOR, BE SURE TO KNOW THE NAME OF THE CITY OR TOWN IN
WHICH YOU ARE STAYING AND THE NAME OF THE COUNTY OR PARISH IN WHICH
IT RESIDES. LISTEN FOR THESE LOCATIONS IN LOCAL NEWS UPDATES. PAY
ATTENTION FOR INSTRUCTIONS FROM LOCAL AUTHORITIES.
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.
RAPIDLY RISING FLOOD WATERS ARE DEADLY. IF YOU ARE IN A FLOOD-PRONE
AREA, CONSIDER MOVING TO HIGHER GROUND. NEVER DRIVE THROUGH A FLOODED
ROADWAY. REMEMBER, TURN AROUND DON'T DROWN!
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.
