From synopsis, high pressure building in behind the recent frontal passage will maintain fresh to occasionally strong breezes through tonight. Breezes will slacken appreciably beginning Friday, with light to gentle breezes expected for the weekend into early next week. Issued at 534am EDT Thu Mar 19 2026 Small Craft Advisory is in effect for all of the coastal waters and the current Reef observations support that recording near 20 knots. While showers are possible throughout today, models are suggesting a majority of the activity will remain in the Straits. High pressure has built in behind the recent cold front passage earlier in the week. This has resulted in fresh to occasionally strong breezes across the coastal waters. These fresh to strong breezes will start to slacken overnight into Friday as the high starts to lose it's grip. As the weekend unfolds, rain chances will decrease with only a slight chance expected through early next week. Temperatures will start to gradually warm back up from our brief cool temperatures, though the dew points will remain near 60 making for a pleasant few upcoming days!
