COASTAL WATERS FROM STONINGTON ME TO MERRIMACK RIVER MA OUT TO 25 NM

ANZ100-021100-
502 PM EST Mon Dec 1 2025

.Synopsis for Stonington ME to Merrimack River Ma out to 25 NM...
Gusty winds continue across all waters this afternoon until high
pressure settles over the region tonight and allows them to diminish
along with seas. This will be only a brief break as a strong and
deepening coastal storm will pass just off Cape Cod and race east
northeast. This will spread mostly rain over the coastal waters until
Tuesday night when colder air moves in and flips precipitation nearer
the coast to heavy snow. Marginal gale force wind gusts are possible
in the wake of the storm Tuesday night into Wednesday and the rest of
the week looks to remain gusty. An Arctic front will cross the waters
Thursday and bring another period of potential northwesterly gales.
High pressure will build in Friday and allow winds and seas to
gradually diminish.
