922 PM EDT Wed Apr 9 2025

.Synopsis for Stonington ME to Merrimack River Ma out to 25 NM
High pressure slides east over New England tonight and settles into
the Gulf of Maine Thursday. This will allow winds and seas to
diminish. The high then settles across the Canadian Maritimes
through the weekend while low pressure over the Mid Atlantic slowly
migrates northward along the East Coast. This system will bring
increasing northeast flow and building seas Saturday and Sunday.
