------------------
HURRICANE IDALIA CONTINUES TO STRENGTHEN IN THE FAR 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

CURRENTLY MAKING ITS CLOSEST APPROACH TO THE LOWER KEYS, ABOUT 190
MILES TO THE WEST OF KEY WEST. OUTSIDE OF ANY SQUALLS, TROPICAL STORM-
FORCE WIND GUSTS WILL CONTINUE THROUGH LATE THIS EVENING, PARTICULARLY
ALONG AND WEST OF THE LOWER KEYS. INSIDE SQUALLS, STRONG, POTENTIAL
DAMAGING WIND GUSTS WILL BE POSSIBLE. THE PERSISTENT SOUTHERLY WINDS,
ALONG WITH KING TIDES, MAY CONTINUE TO RESULT IN COASTAL FLOODING OF
AROUND 2 FEET ABOVE NORMAL HIGH TIDES. THIS WAS OBSERVED AT THIS
MORNING'S HIGH TIDE AND WILL LIKELY OCCUR AGAIN AT AROUND THE TIME OF
HIGH TIDE WEDNESDAY MORNING. IN ADDITION, RAINFALL OF 1 TO 2 INCHES,
WITH LOCALLY HIGHER AMOUNTS, AND FEW TORNADOES 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
REPORT FACILITIES AND SERVICES WILL REMAIN OPEN. MEDICAL SERVICES AND
THE KEY WEST INTERNATIONAL AIRPORT REMAINS OPEN. HOWEVER, THERE HAVE
