KEY MESSAGES

- Heat indices may approach 105 to 110 degrees each afternoon for some Florida Keys island communities, especially in the Upper Keys.
DISCUSSION
Issued at 1105 PM EDT Tue Jul 28 2026 A mostly uneventful night for the Florida Keys. KBYX is currently shower free which is mostly what we've seen for the last few hours. A surge of winds in the eastern most waters occurred earlier this afternoon resulting in Small Craft Should Exercise Caution headlines for the eastern portions of the Hawk Channel. Now, marine locations are observing winds of 10 to 15 knots throughout the Reef therefore the headline has been taken down. Temperatures along the island chain are in the mid 80s with dewpoints in the mid 70s making for another muggy summer night. Tomorrow, another wind surge is possible and Exercise Caution headlines could be put into place again if winds become elevated like this afternoon in the easternmost waters. Showers are expected to be limited for tonight and tomorrow advertising only a slight chance in the forecast.
MARINE
Issued at 1105 PM EDT Tue Jul 28 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys. From synopsis, troughing just off the Eastern Seaboard will continue to reach southwestward across the far southeast for the next day and be reinforced by another shortwave. This will result in a broad confluence zone remaining draped across northern Florida/Georgia for much of this week. Generally light to gentle breezes will continue out of the southwest to west, but may variable at times. Breezes will become gentle to moderate towards mid week before slackening back to light to gentle by late week.
AVIATION
(00Z TAFS) Issued at 1105 PM EDT Tue Jul 28 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Dry air will limit shower development through tonight therefore no mention of VCSH at either terminal. Near surface winds will be southwest to west at near 10 knots.
