.MARINE... Variable sub-SCA level winds are occurring this morning. By late morning, the prevailing direction will become southerly and gradually pick up in magnitude by tonight, especially along the bay. At this time, the greatest chance for channeled gusts to near 20 kt appears to be between Pooles Island and Drum Point, where an advisory has been issued.Winds will increase across all waters after sunrise Thursday, with advisories likely needed. Some thunderstorms with gusty winds could reach the waters later Thursday afternoon or evening. Winds may decrease for a time late Thursday night into Friday morning as the front fizzles out, but additional advisories will likely be needed later Friday into Friday night while southerly flow remains in place. SCA conditions are likely Saturday into early next week both in the pre-frontal and post-frontal environment. Strong t-storms Saturday afternoon may also require SMWs. Update as of: 400 AM EDT Wed Sep 3 2025
