MARINE

A Small Craft Advisory remains in effect on the ocean waters through early this evening. Winds will likely be marginal and overall below 25 kt, but there still may be a few gusts nearshore around 25 kt. Seas should build to 5-6 ft, especially east of Fire Island Inlet. 5 ft seas could linger east of Moriches Inlet into the evening, so have extended the SCA for these waters until 11 pm.

In addition to the elevated seas and marginally gusty winds, a cold frontal passage late Wednesday afternoon into Wednesday evening will bring with it the potential for strong to severe thunderstorms with gusts in excess of 35 kt.

Conditions tonight through Friday are expected to remain below SCA levels with a cold front south of the waters. The next chance for SCA conditions will be this weekend as several waves of low pressure pass along the cold front to our south.
