.MARINE... Southerly winds are expected over the waters today. Gusts may near low-end SCA levels, but the current expectation is that warmer air moving over cooler waters will limit the strength of gusts. The Upper Tidal Potomac and immediate shoreline of the Bay would likely stand the greatest chance of having a few low- end SCA gusts, if they were to occur at all. A cold front will move over the waters tonight, causing winds to shift to out of the north. Winds will then turn to out of the northeast and eventually east on Saturday while remaining sub-SCA level in magnitude. An area of low pressure will track along a stalled front just to our south. If this system were to trend a bit further north, SCA gusts could be possible over the southernmost waters (Smith Point to Tangier Sound) later Saturday afternoon into Saturday evening. For now, winds are expected to remain sub-SCA level over all waters. Winds will turn out of the northwest as a cold front crosses over the waters Saturday night, and continue out of the northwest through the day Sunday. At least high-end SCA gusts appear likely during that time, with Gale gusts possible at times. SCA conditions remain possible again on Monday, with gusty NW winds around 20 knots. Winds taper off quickly Monday night into Tuesday, with no marine hazards expected during that time. Update as of: 403 AM EST Fri Jan 9 2026
