In addition to the hazards inland with this storm (rain, gusty winds, high elevation snow), winds and seas will be hazards with this storm.
A Wind Advisory has been issued for the Downeast Coast through late-morning Friday. Winds could gust up to 50 mph at the immediate coast and on the outer islands late tonight into Friday morning.

Additionally, a Gale Warning is in effect for all waters through late Friday morning. Wind gusts up to 45 kts are expected, along with wave heights of 8-13 feet during that time.
Coastal flooding is not expected with this system. This is due to offshore winds and the highest storm surge coinciding with low tide. However, there may still be some isolated overwash due to high waves.
