Coastal Flood — Dorchester, MD

Oct 12, 2025

A coastal low formed off of the Southeast coast on October 11 and slowly tracked north into October 13 before moving offshore. Meanwhile, a strong 1035mb area of high pressure lingered over the Gulf of Saint Lawrence. This resulted in a prolonged period of strong northeast to north winds across the Chesapeake Bay and coastal waters, which allowed for widespread moderate coastal flooding across the lower Maryland Eastern Shore on October 12 into October 13.
