Boston, Massachusetts – Hazardous marine conditions are escalating as building seas and high winds are projected to dominate the coastal forecast through the coming weekend. While the most dangerous conditions are expected over southern offshore waters, coastal communities should prepare for increasing wind speeds beginning as early as Tuesday afternoon.
According to the National Weather Service in Boston , there is a significant risk for gale force gusts exceeding 40 mph beginning early Thursday morning, with probabilities reaching 70% in certain southern coastal sectors. Seas are expected to build to 10–15 feet by midweek and could surge as high as 15–20 feet by Friday.
Marine interests, including commercial fishing vessels and recreational boaters, should monitor the Gale Watch closely, as it may be extended to additional zones. The combination of high winds and choppy, building seas creates life threatening conditions for small craft, and beachgoers should avoid coastal areas during the peak of the storm.
The situation requires constant vigilance as the system moves into the region. Keep track of updated marine advisories, as the timing of the most severe wind gusts could shift based on the storm's track near the weekend.
