SECTOR BOSTON MSI/SECTOR BOSTON, SUBMERGED LAND ACT (SLA)
General / MSIB
Potential Heavy Weather Impacts September 23 - 28, 2026 SUMMARY: Due to the approach of forecasted gale-force winds, the Captain of the Port, Coast Guard Sector Boston is urging the public to exercise extreme caution and strongly advising boaters against operating in adverse weather conditions. During this time, the Coast Guard’s ability to respond to emergencies may be degraded. Maritime stakeholders should review continuity of operations and communication procedures, as well as methods of minimizing storm damage and environmental risk, such as riding out the storm at sea, doubling up mooring lines, securing transfers, ballasting down storage tanks and draining transfer lines. SITUATION: The National Weather Service has issued a Gale Warning for Boston Harbor, and the coastal waters of Massachusetts. Sustained northeast winds between 35-40 knots with gust exceeding 55 knots are expected. Hazardous marine conditions are expected for a sustained period from late Wednesday night to early Monday morning due to strong winds and 15–20-foot seas potentially building to 25 feet offshore. Conditions will include significant rainfall, potential for minor coastal flooding, and moderate coastal erosion due to storm surge during periods of high tide. Mariners should consider altering plans to avoid possible hazardous conditions. Remain in port, seek safe harbor, alter course, and/or secure the vessel for severe wind and waves. Marinas, Yacht Clubs, and private residents are encouraged to secure all paddle craft and small boats to prevent unintentional drifting out to sea. Due to the high winds, regional draw bridge operations may be impacted. MONITORING: Vessels at facilities shall carefully monitor their moorings and cargo operations. Vessels at anchor shall prepare for heavy winds. Additional anchor(s) should be made ready to let go and preparations shall be made to have a continuous anchor watch. Engine(s) should be made immediately available for maneuvering. Mariners should maintain a continuous listening watch on VHF Channel 16 and are advised to monitor the latest forecasts from the National Weather Service or other weather media outlets as conditions and forecasts may change. COMMUNICATIONS: For urgent safety of life issues, please contact the Sector Boston Command Center on VHF-FM Channel 16 or call (833) 449-0539. Additionally, please check USCG Navigation Center often for updates to the public from the US Coast Guard. Questions regarding this bulletin may be address to Lieutenant Commander Jessica Hull, Chief of Waterways Management Division at (617) 512-9615 or Mr. Timothy Chase, Deputy Chief of Waterways Management Division at (617) 447-1620 or email at [email protected].
