Westerly gale force gusts are likely through tonight tonight over the outer waters. Winds and seas will gradually diminish into the weekend as high pressure builds across the Gulf of Maine. The high shifts east Sunday as another cold front approaches and then crosses the waters Sunday night with another period of gales possible both ahead of behind the front. High pressure then builds back in Monday before a coastal low potentially brings increased winds and seas Tuesday into Wednesday of next week. $$ ANZ154-290800- Coastal Waters from Cape Elizabeth, ME to Merrimack River, MA out 25 NM- 1240 PM EST Fri Nov 28 2025 ...GALE WARNING IN EFFECT THROUGH SATURDAY MORNING... .THIS AFTERNOON...W winds 20 to 25 kt with gusts up to 40 kt.
