.MARINE... Southeast flow will remain gusty until a lull occurs overnight for most waters. Winds will likely remain elevated over the wider waters off southern MD, though. An abrupt shift to the northwest is expected between 4 AM and 8 AM Sunday from northwest to southeast, with gusts of 30-40 kts for a brief time likely necessitating Special Marine Warnings even if there is little to no precipitation as a strong cold front crosses the waters. Showers and gusty winds (SCAs) linger behind the front, with drying expected by Sunday afternoon. Winds become lighter Sunday night then increase again Monday with a secondary front. Light winds Monday night turn southerly Tuesday with additional SCAs possible by Tuesday night. Small Craft Advisories may be needed Wednesday morning as winds flow southerly with gusts up to 20-25 knots before gradually decreasing later in the day. Winds shift to northerly overnight with winds on Thursday likely falling below SCA criteria. Update as of: 928 PM EDT Sat Apr 18 2026
