Forecast summary

Marine conditions synopsis

Moderate easterly winds of 15 to 20 kt will continue across the coastal waters tonight, with Small Craft Advisory conditions lingering over portions of the waters through midnight. As the pressure gradient relaxes ahead of the approaching cold front, winds will gradually decrease and become more southeasterly Tuesday. Showers and a few thunderstorms will be possible Tuesday night into Wednesday as the front moves through the waters. Winds will shift offshore behind the front Wednesday, but with limited cold air advection and a relatively weak pressure gradient, a significant postfrontal wind surge is not expected. This should allow seas to gradually subside through Thursday. Another weak cold front will move through Friday, followed by a potentially stronger front late in the weekend that could bring another increase in offshore winds.
