.MARINE... SCA conditions are expected later this morning and into tonight as a weak front pushes through the region. A few light showers may accompany the front especially over northern portions of the bay and tidal Potomac. Any of these showers have the potential to bring down gale force winds between 11am this morning and 5pm this afternoon. SCA conditions will persist through the front half of the overnight period, with winds turning lighter Sunday as brief high pressure builds nearby. SCA conditions are likely again on Monday as a strong cold front pushes through the region. This front will bring another round of gusty showers especially during the afternoon and evening hours. Winds will drop back below SCA criteria Monday night. Initial winds will be out of the southwest to westerly direction on Tuesday. A system passing through should bring some showers across the waters late Tuesday with winds shifting to northwesterly by Wednesday. As the cold front moves through, there may be some uptick in winds which would approach Small Craft Advisory levels. Update as of: 355 AM EDT Sat Mar 22 2025
