KEY MESSAGES
- Fog will be possible this evening across portions of the Keys due to high dew points and light breezes clocking northwest to north. - A strong high pressure system sinking into the northern Plains from Canada is forecast to freshen breezes early next week. Breezy conditions are possible at times. - A 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 140 PM EST Sat Feb 28 2026
Periodic MVFR CIGs are currently observed at EYW and MTH ASOS observations due to cloud streamers developing along the island chain. These ceilings will likely be sporadic and short lived if further observed. Thinking for conditions later today has not changed. Light near surface winds will turn to the north later today and low ceilings and fog will be possible as it advects in from the Gulf. Uncertainty is still relatively high as these features have yet to coalesce and depends on when the wind direction changes from variable to northerly. Decided to leave the line in with the northerly wind shift that describes lower CIGs and VIS but opted to keep it in VFR conditions due to uncertainty for now.
MARINE
Issued at 1113 AM EST Sat Feb 28 2026
No watches, warnings, or advisories are currently in effect for the coastal waters of the Florida Keys. From synopsis, an Atlantic ridge across South Florida will pull further east while a frontal boundary stalls across north central Florida. The combination of these features will result in light breezes likely becoming variable later today. Thereafter, a broad high pressure system is forecast to migrate into the eastern United States, then out into the Atlantic. This is expected to support freshening breezes, especially across the Straits of Florida. A mix of Cautions and Advisories is becoming increasingly likely for the bulk of the work week.
