Multiple U.S. marine regions remain under Gale Warnings Tuesday, with hazardous winds and seas impacting the Mid-Atlantic, Great Lakes, Northeast coastal waters, and portions of the eastern Pacific, according to the National Weather Service.
Gale Warnings are in effect for large sections of the Chesapeake Bay, Tidal Potomac River, and Baltimore Harbor, where west winds of 25 to 40 knots and waves of 2 to 4 feet are expected through Tuesday evening. Small Craft Advisories follow overnight into Wednesday as winds gradually ease.
Across the Great Lakes, especially Lakes Superior, Michigan, Huron, Erie, and Ontario, sustained northwest winds of 30 to 35 knots with gusts up to 45 knots are producing dangerous wave heights ranging from 12 to 30 feet in open waters. Portions of Lake Huron and Lake Superior are also under Heavy Freezing Spray Warnings, with ice accumulation rates exceeding 2 cm per hour, posing a severe stability risk to vessels.
Along the New England and Mid-Atlantic offshore Atlantic waters, Gale Warnings extend from Cape Cod and Georges Bank southward to waters off Virginia and North Carolina, with seas building between 10 and 20 feet and sustained winds of 30 to 45 knots through Wednesday morning.
In the eastern Pacific, Gale and Storm Warnings are posted offshore of southern Mexico, including the Gulf of Tehuantepec, where northerly winds of 35 to 45 knots and seas up to 18 feet are forecast.
The National Weather Service advises mariners to remain in port or seek safe harbor, as these conditions are capable of capsizing or damaging vessels and significantly reducing visibility.
