.MARINE... Made several adjustments to the Small Craft Advisory. Southerly channeling gusts continue to affect the narrower portion of the bay north of Drum Point through midday. It appears all waters except perhaps the Potomac from Indian Head to Cobb Island could experience gusts up to 20 knots throughout the afternoon and early evening. The stronger winds will gradually contract to the main channel tonight. Some convective potential late in the evening to early overnight may require Special Marine Warnings. However, confidence is low at this time. Small Craft Advisories may be needed early Sunday and again behind a cold front late Sunday into Monday. In between, strong to severe thunderstorms could impact the waters during the late afternoon to early/mid evening. Special Marine Warnings become likely with this activity before the convection pushes off to the east overnight. Light and variable winds Tuesday morning before southwesterly in the afternoon and are expected to remain below SCA criteria. Small Craft Advisories are possible Wednesday as southerly winds gust over 15 knots in the afternoon. Update as of: 1010 AM EDT Sat Jun 29 2024
