Synopsis
High pressure settles over the waters tonight with light winds. The late week will feature southwest return flow developing. Some of those gusts may approach 25 knots on the coastal waters north of Port Clyde, with seas in the vicinity of Skate Bank approaching 5 feet. Otherwise the weather on the waters looks awfully quiet for this time of year.
