| Area Forecast Discussion National Weather Service Key West FL 1013pm EDT Fri April 10 2026 Issued at 1010pm EDT Fri April 10 2026 There has been a significant downward trend in shower activity over the past couple of days due to drier air that has been filtering into the area. To put it into perspective, the 00Z sounding from 48 hours ago calculated a PWAT (Precipitable Water) value of 1.68" while the 00Z sounding from this evening only calculated 1.25". Most of this water is confined to the lower levels, so the current shower activity tracking across the forecast area is both shallow and quick-moving. If any of these showers cross the island chain, rainfall totals will be minimal, at best. Satellite data estimates PWAT (Precipitable Water) values just under an inch are advecting into the area, so the slight chance, 10%, of rain from the inherited forecast seems reasonable. Breezy to occasionally windy conditions have continued through this evening, and still do not look like they are slackening anytime soon. High pressure is gradually building into the south/southeastern U.S. and this is maintaining a tight pressure gradient. Automated observations from both Key West and Marathon International Airports have consistently reported winds of 15 to 20 mph with frequent gusts near 25 mph. Marine platforms have reported slightly higher winds, since we see less friction over the waters. Observations over the waters near the island chain have reported sustained winds near 23 mph, or near 20 knots, with gusts near 28 mph, or near 25 knots. This dry and breezy to windy pattern will continue throughout the night as the current forecast package shows. No changes are proposed with this evening update. Marine Issued at 1010pm EDT Fri April 10 2026 A Small Craft Advisory remains in effect across all Florida Keys local waters. From synopsis, fresh to strong breezes will persist across all Florida Keys coastal waters through the weekend, and into the start of the new week. A Small Craft Advisory is in effect. There is high confidence breezes will not begin to slacken to moderate to fresh until at least Tuesday. Drier air will gradually move towards the Florida Keys, so occasional shallow showers will linger through tonight. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...Small Craft Advisory until 6am EDT Saturday for GMZ031>035- 042>044-052>055-072>075. |
