KEY MESSAGES
- Strong high pressure over the central North Atlantic will remain stationary through the rest of the week into the weekend, supporting an extended period of relatively unremarkable weather. - Moderate to fresh breezes will wax and wane the rest of the week, generally peaking during the overnight hours and lulling in the afternoons.
- Rain, with possible thunder, chances expected to increase late into the week into at least the first part of the weekend. - Moderate drought continues for the entire island chain. Burn bans are possible, trees and bushes begin browning, and water supply decreases. For the upcoming week, there will be a slight chance for showers.
AVIATION
(18Z TAFS) Issued at 1148 AM EST Wed Mar 4 2026 Passing showers will be possible in the moderate to fresh low- level easterlies, especially after 00z this evening through sunrise Thursday morning. With that said, VFR conditions will prevail, with limited impacts to CIGs and visibilities expected at this time from any brief shower. Due to the lack of coverage, minimal impacts, and lack of confidence in timing, will keep mention of VCSH out of the TAFs for now. The easterly breezes will frequently gust to near 20 knots at the terminals.
MARINE
Issued at 1024 AM EST Wed Mar 4 2026 Small Craft Exercise Caution headlines are posted for all Keys marine zones south of the Island Chain. These may need to be extended this evening, and they may also be upgraded to Small Craft Advisories in some marine zones due to expected freshening breezes overnight. From synopsis, a large and robust high remains centered over the central North Atlantic. This will continue to promote a prolonged period of moderate to fresh breezes across Florida Keys coastal waters through the remainder of the week and into the weekend. Winds will be strongest across the Florida Straits and weakest over the cooler Gulf side waters.
