| Area Forecast Discussion National Weather Service Key West FL 213pm EDT Tuesday Jun 16 2026 Issued at 344am EDT Tuesday Jun 16 2026 High pressure located in the southwestern North Atlantic and stretching well west into the Gulf Basin will maintain deep layer subsidence across the region. This coupled with a south-southeast steering flow will only add to the inhibition of any shower activity for today. Meanwhile, remnants of a tropical wave that moved across Mexico will enter the northwest Gulf waters off the Texas coast and move along the periphery of said high up into the North Gulf States this week. At the same time, the high pressure will strengthen slightly, maintaining its grip across the Florida Keys. This will not only keep rain chances very low (near 10 percent or less), but it will briefly allow winds to increase slightly Wednesday through Friday. In addition to a potentially extended dry period, dew points and temperatures will be slowly creeping upward through the week. This will result in heat indices reaching and exceeding 100 degrees this week, especially in the Upper Keys. This will lead to an increase in the heat risk for the Keys, particularity those more sensitive to heat. Conditions will be borderline for heat-related products and will be reassessed as the week progresses. Regardless, extra precautions should be taken this week if you plan on being outdoors for an extended period of time. Marine Issued at 1050am EDT Tuesday Jun 16 2026 There are no watches, warnings, or advisories in effect across the Florida Keys local waters. From synopsis, light to gentle breezes will persist through the middle of the week across the Florida Keys coastal waters. Starting Tuesday night and Wednesday, the Mid-Atlantic high will begin to strengthen and support slightly fresher breezes through the end of the week. Shower and thunder chances are expected to remain very low through the forecast period. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
