Latest Marine Discussion:

.MARINE... Northeasterly winds prevail today. There may be a brief uptick along the bay around sunrise, but any gusts that near advisory levels should be short lived. Winds switch to southerly on Wednesday as high pressure moves off the east coast. While southerly channeling may impact the bay Wednesday night, the chance for advisories seems to have trended down a bit. That won't be the case Thursday and Thursday night as flow increases ahead of a cold front. Advisories will likely be needed for all waters. Some gusty thunderstorms could reach the waters during the evening, but current trends suggest they will be in a weakening state. SCA conditions are likely Friday through Sunday. Update as of: 359 AM EDT Tue Sep 2 2025
