SOUTHEASTERN GULF OF MEXICO. THERE HAVE BEEN NO CHANGES TO FLORIDA KEYS
WATCHES AND WARNINGS, WITH A TROPICAL STORM WARNING REMAINING IN
EFFECT FOR THE DRY TORTUGAS AND A TROPICAL STORM WATCH FOR THE LOWER
KEYS. IDALIA WILL CONTINUE TO ACCELERATE TO THE NORTH TODAY, THEN TO

NORTHWARD, FOLLOWED BY SOME UNCERTAINTY REGARDING AN EXPECTED TURN TO
THE NORTHEAST AND TOWARDS FLORIDA'S BIG BEND REGION. AT ITS CLOSEST
POINT OF APPROACH, THE CENTER OF IDALIA WILL PASS WELL TO THE WEST OF
THE FLORIDA KEYS DURING THE DAY TODAY. WINDS IN THE KEYS WILL CONTINUE
TO STRENGTHEN GRADUALLY THROUGH THE MORNING AND EARLY AFTERNOON HOURS,
PEAKING THIS AFTERNOON. TROPICAL STORM-FORCE WIND GUSTS WILL BE
POSSIBLE, PARTICULARLY ALONG AND WEST OF THE LOWER KEYS, AND DURING
OCCASIONAL THUNDERY SQUALLS. CONVECTIVE BANDING CONTINUES TO ADVANCE
EASTWARD ACROSS THE WESTERN HALF OF THE FORECAST AREA, WITH INDIVIDUAL
CELLS MOVING NORTHWARD AT AROUND 50 MPH. THE PERSISTENT SOUTHERLY
WINDS, ALONG WITH KING TIDES, MAY RESULT IN COASTAL FLOODING OF AROUND
2 FEET ABOVE NORMAL HIGH TIDES. IN ADDITION, RAINFALL OF 1 TO 3 INCHES,
WITH LOCALLY HIGHER AMOUNTS, AND A TORNADO OR TWO CANNOT BE RULED OUT.
CONDITIONS ARE EXPECTED TO GRADUALLY IMPROVE TONIGHT INTO WEDNESDAY,
ALTHOUGH STRONG SOUTHERLY BREEZES WILL PERSIST THROUGH MUCH OF THE DAY
ON WEDNESDAY.
NO EVACUATIONS HAVE BEEN ORDERED. MONROE COUNTY AND CITY OF KEY WEST

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
IF YOU ARE EXCEPTIONALLY VULNERABLE TO WIND OR WATER HAZARDS FROM
TROPICAL SYSTEMS, CONSIDER VOLUNTARY EVACUATION, ESPECIALLY IF BEING
OFFICIALLY RECOMMENDED. RELOCATE TO A PREDETERMINED SHELTER OR SAFE
DESTINATION.

GUSTS, STORM SURGE, AND TORNADOES EXTEND WELL AWAY FROM THE CENTER OF
THE STORM.
WHEN SECURING YOUR PROPERTY, OUTSIDE PREPARATIONS SHOULD BE CONCLUDED
AS SOON AS POSSIBLE BEFORE CONDITIONS DETERIORATE. THE ONSET OF STRONG
GUSTY WINDS OR FLOODING CAN CAUSE CERTAIN PREPAREDNESS ACTIVITIES TO
BECOME UNSAFE.
CLOSELY MONITOR WEATHER.GOV, NOAA WEATHER RADIO AND LOCAL NEWS OUTLETS
FOR OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES TO THE
FORECAST.
