.MARINE... Wind fields through Sunday morning remain on the lighter side given weak gradients in place. South to southeasterly wind gusts should stay around 10 knots or less with dry conditions expected. As what remains of Tropical Storm Chantal moves onshore into the Carolinas, there will be a gradual uptick in the south-southeasterly flow. Most start to see 10 to 15 knot gusts for the second half of Sunday, locally up to 20 knots in the southern waters. As such, channeling effects over these waters may require Small Craft Advisories from Sunday evening into the night. Afternoon/evening thunderstorm chances increase by Monday which may lead to hazardous marine conditions. In addition to the potential for frequent lightning, Special Marine Warnings may be needed for any strong storms. Any convection should wane into the overnight hours. Showers and thunderstorms are possible over the waters as a cold front approaches the forecast area next week. Winds are expected to stay below SCA criteria on Tuesday and Wednesday, although SMWs are possible during afternoon showers and thunderstorms. This pattern will likely continue for the remainder of the week as well. Update as of: 245 PM EDT Sat Jul 5 2025
