DISCUSSION
Issued at 422 AM EDT Wed Apr 30 2025 The Florida Keys are experiencing a mostly peaceful morning. KBYX is detecting a little cluster of showers moving west, currently located near Cudjoe Key. Looking at some of the local rain gauges near the area, it appears they got a decent shower recording 0.32 inches of rain in Big Pine Key. As for now, the rest of the Island Chain has remained dry. Temperatures overnight dropped into the mid 70s, which is where they are being recorded at now as well.
Along the Reef, winds have slightly slackened to 15 to 20 knots, allowing for us to drop the Small Craft Advisory headline but are high enough to keep Small Craft Should Exercise Caution in all of the waters. MIMIC Precipitable water shows dry air making its way from the Bahamas towards our area. For today, shower activity is possible this morning but as this dry air enters our area, it should limit any other activity beyond that.

After this dry air moves into our area, it is expected to stick around for the next few periods resulting in near nil PoPs through Thursday. Thereafter, the return of tropical moisture will occur as the high pressure moves into the western North Atlantic and the wind direction becomes east to southeasterly. Winds for the next few days will continue to oscillate with moderate to fresh breezes teetering the line of Small Craft Advisory conditions, but as the high continues eastward these winds will slacken further giving brief relief from elevated winds. Towards the end of the weekend into early next week, another high will build across the East Coast bringing another round of freshening breezes. Stay tuned.

MARINE
Issued at 422 AM EDT Wed Apr 30 2025 No watches, warnings, or advisories are currently in effect for the Florida Keys waters, although, Small Craft Should Exercise Caution for moderate to occasionally fresh breezes in all waters.
From synopsis, moderate to fresh breezes will continue as high pressure dominates the region. The high will remain fairly stagnant in place through the middle of the week, so breezes will oscillate between moderate to fresh on a weak diurnal trend with stronger breezes in the evening hours. Occasional pushes of moisture throughout the week will allow for some isolated shower activity.

AVIATION
(06Z TAFS)
Issued at 422 AM EDT Wed Apr 30 2025 VFR conditions will prevail at both terminals through 01/00z.
Easterly winds will slacken slightly later this morning and continuing into the afternoon, but will freshen once again in the evening. Gusty winds up to 20 knots will be possible at times.
Additional low level moisture overnight coupled with the nocturnal surge may result in isolated showers passing over the terminals. At this time, however, confidence on converage is too low to include mentions of VCSH.

KEY WATCHES/WARNINGS/ADVISORIES
FL...None.
GM...None.
