KEY MESSAGES

- Strong high pressure over Bermuda will remain stationary through the weekend, supporting an extended period of relatively unremarkable weather. - Moderate to fresh breezes will wax and wane through the weekend, generally peaking during the overnight hours and lulling in the afternoons. - 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.

DISCUSSION

Issued at 1037 PM EST Sat Mar 7 2026 Breezy and mostly dry conditions have prevailed through the evening along the Florida Keys, including our local waters. Satellite derived products have shown partly cloudy skies in general with some enhanced cloud coverage over the portions of the Florida Straits near ongoing Cuban convection. Closer to home, our KBYX radar showed a small cluster of moderate showers emerge from Andros Island, and track westward toward the Upper Keys. By the time it reached our marine zones, it slowly fizzled out. There are only a couple of automated observations along the Upper Keys, and none of them reported any rainfall this evening, but some of the Florida DOT traffic cameras in the vicinity had raindrops on their lens! With moderate drought conditions still in place, we will take any rain we can get. The 00Z KKEY sounding from this evening shows a fair amount of instability in the lower levels, so we can't rule out occasional, light showers overnight. Thus, the forecast is unfolding as expected, and no updates or changes are proposed at this time.

MARINE

Issued at 1037 PM EST Sat Mar 7 2026 A Small Craft Advisory is in effect for the Florida Straits. Elsewhere, Small Craft SHould Exercise Caution across the rest of the local waters due to easterly winds of 15 to 20 knots. From synopsis, high pressure is centered over Bermuda with the western periphery of this ridge extending west into Florida and the Gulf. This will continue to promote moderate to fresh breezes tonight. Slight weakening of the high Sunday into early next week will result in modest slackening to gentle to moderate breezes, though, moderate to fresh breezes are expected to continue across the Straits. As the high retreats into Atlantic next week, breezes will shift to the east to southeast.

AVIATION

(00Z TAFS) Issued at 1037 PM EST Sat Mar 7 2026 VFR conditions will prevail at both island terminals through the TAF period, but infrequent and short lived observations of MVFR CIGs are possible at both locations due to SCT to BKN decks near FL030. LOng term impacts are unlikely at both air fields. Rain chances are near 20 percent for the area, but any showers will be short lived. TAFs will continue to reflect dry weather conditions.
