KEY MESSAGES

- Strong high pressure centered over the central North Atlantic stretches southwestward into Florida and the Gulf. This will aid in breezy, possibly windy, conditions continuing through much of the week.

- The fast flow and modest moisture will result in chance of showers over the next couple of days.

- Moderate drought conditions will continue across the Keys for the foreseeable future. Even though showers are in the forecast over the next several days, it is not expected to be nearly enough to dent the drought conditions.

AVIATION

(18Z TAFS) Issued at 131 PM EDT Tue Mar 31 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. While some brief light showers are possible through this evening as moisture lingers in the area, mention in the TAFs are not necessary at this time. Near surface winds will be easterly at 10 to 15 knots with occasional gusts of 20 to 25 knots.

MARINE

Issued at 1117 AM EDT Tue Mar 31 2026 A Small Craft Advisory is in effect for the Straits of Florida, Hawk Channel, and Florida Bay and the nearshore Gulf waters. From synopsis, strong high pressure across the central North Atlantic will meander east for several days. As a result, expect easterly fresh breezes, occasionally strong, especially in the Straits to prevail through the week. Breezes will also occasionally peak overnight into the morning hours and lull in the afternoon and evening hours, especially north of the Island Chain and across the SE Gulf.

FORECAST

Strong high pressure across the central North Atlantic will meander for much of the week. This will keep the mainly easterly flow in place for several days. Therefore, expect breezy to potentially windy conditions to continue through much of next week as a result. Moisture undulations around the high will result in episodic showers with some periods wetter than others. Instability will remain weak today through Wednesday. However, modest instability returns for Wednesday night through Friday resulting in slight chance thunder returning to the forecast. Temperatures will remain near normal for this time of the year with daytime highs in the lower 80s and overnight lows in the lower to mid 70s. Dew points will also remain quite steady in the mid to upper 60s, occasionally near 70 degrees.
