.MARINE... Small Craft Advisories remain in effect in the main stem of the Bay through noon within northerly flow. There will likely be a small lull in the winds this afternoon, before they pick up again in earnest within northeasterly flow later tonight into tomorrow as high pressure strengthens to our north. A prolonged period of northeasterly winds is expected through Wednesday with that area of high pressure in place. Small Craft Advisories have been issued again starting tonight and continuing through Tuesday night. At least high-end Small Craft Advisory gusts will continue within northeasterly flow through at least Wednesday. Low- end Gale gusts can't be ruled out late Tuesday night into Wednesday across the widest waters of the Bay, but confidence in that occurring was too low for Gale Watches at the moment. High end small craft conditions will continue through Friday due to increased onshore north to northeasterly flow. Expect gusts between 20-25 kts with 30 kt gusts sporadically sprinkled over the middle and open waters. On and off showers are also possible at times as multiple shortwave disturbances pivot through. SCA conditions will likely continue through the weekend as low pressure remains off the Mid-Atalntic coast. Strongest gusts will be over the bay and lower tidal Potomac. Update as of: 406 AM EDT Mon Sep 21 2026
