DISCUSSION

Issued at 359 AM EDT Sat Mar 21 2026 An uneventful overnight into morning has unfolded for the Florida Keys. KBYX radar has remained shower free for the last several hours. Nighttime Microphysics depicts mostly clear skies. Last night's 00z sounding revealed a dry profile, with 0.90 inches of precipitable water measured, which validates the lack of cloud coverage in the area. Temperatures along the island chain are currently near 70 with dewpoints in the lower 60s, making it feel really nice outside. Along the Reef, winds have slackened to 10 to 15 knots. The Small Craft Advisory has been taken down due to slackening of the winds and subsiding of seas, though in the Straits Small Craft Should Exercise Caution until winds decrease and seas subside headlines are still in place. For today, nothing too different from what we've been experiencing is expected, mostly sunny skies, highs in the mid 70s and light to gentle breezes.

As high pressure continues to be the main feature dominating the weather for the Florida Keys, not much is expected to change over the coming days. Due to the dry air over the area, near nil rain chances are expected and mostly clear skies. As the pressure gradient loses its grip light to gentle winds will stick around for most of the week. This should play out to be a nice first half week but stay tuned for any updates!

MARINE

Issued at 359 AM EDT Sat Mar 21 2026 No watches, warnings, or advisories are in effect for the Florida Keys, though Small Craft should exercise caution in the Straits of Florida until winds and seas decrease. From synopsis, Small Craft should exercise caution in the Straits of Florida as winds continue to slacken today. Thereafter, light to gentle breezes will prevail into early next week as ridging weakens pressure gradient allowing for the relief. Along with light to gentle breezes dry air has moved in limited shower activity. Mostly mild conditions are expected through early this week.

AVIATION
