| Area Forecast Discussion National Weather Service Key West FL 1248pm EST Tuesday Mar 3 2026 Marine Issued at 1130am EST Tuesday Mar 3 2026 Small Craft Should Exercise Caution headlines posted in the marine zones south of the Island Chain. These may need to be expanded later this week for additional marine zones, and they may also need to be upgraded to Small Craft Advisories at times. From synopsis, a large and robust high centered off of the New England Coast will lumber east southeastward further into the North Atlantic through the remainder of the week. This will usher in a prolonged period of moderate to fresh breezes across Florida Keys coastal waters. Winds will be strongest across the Florida Straits and weakest over the cooler Gulf side waters. Issued at 430am EST Tuesday Mar 3 2026 The broad high near the Atlantic Coast will gradually migrate east southeastward through the remainder of the week. The western flank of this high will continue to linger across the southeastern United States and continue to support moderate to fresh northeast to easterly breezes. Breezy stretches are likely with winds tending to peak in the evening and lull during the day. Rain chances are expected to remain slight due to a lack of organized forcing and persistent lower to mid level ridging and associated dry layers. An upper southern stream trough is expected to amplify across the southeast Gulf and Caribbean Sea after mid week. The best upper level forcing appears to be well south of our area. Lower level forcing appears to be limited to the ample flux that is already in place. Lower level wind profile is expected have only weak veering and the dry layers will persist through the lower levels. As a result, no significant deviation from slight chance Probability of Precipitation are expected at this time. Sky cover should increase through this stretch due to mid and upper level cloud decks streaming out of the trough. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
