Increasing onshore winds out ahead of a formative strong low pressure system off to our west...will result in Small Craft Advisory conditions progressing from west to east across our coastal waters this evening.
Then...as a very powerful squall line develops out ahead of the approaching cold front tonight...gale force winds (or frequent gusts) and high seas will overtake the marine area...with even stronger winds in the vicinity of any thunderstorms.
These gale conditions will linger for a while out of the west behind the cold front during the first half of Wednesday...before slightly diminishing back to advisory levels out of the northwest into Wednesday night.

Small Craft Advisory in effect until 10 PM EST this evening
