(18Z TAFS) Issued at 215 PM EDT Thu Mar 19 2026 VFR conditions will prevail at both island terminals through 18z Friday afternoon, with only SCT020 CIGs at times. A passing shower cannot be ruled out in the favored late overnight hours, although lack of coverage and limited impacts to VIS and CIGs warrants keeping mention out of the TAFs at this time. Near- surface winds will remain out of the north to northeast at 10 to 13 knots, frequently gusting to near 20 knots. Gusts will become less frequent late in the TAF period. && .MARINE... Issued at 940 AM EDT Thu Mar 19 2026 A Small Craft Advisory remains in effect for all Keys marine zones. 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. && .PREV DISCUSSION... Issued at 534 AM 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! && .PRELIMINARY POINT TEMPS/POPS...
