Middlesex County Flood History

Coastal Flood — Oct 28, 2025

Low pressure off the Mid-Atlantic coast combined with high pressure in Canada, resulting in a lengthy period of northeasterly onshore flow. Increasing tidal anomalies resulted in moderate to locally major tidal flooding over an extended period.

Coastal Flood — Aug 21, 2025

Hurricane Erin passed well offshore and combined with high pressure to the north, resulting in a period of strong onshore winds and coastal flooding across eastern Virginia and the Virginia Eastern Shore.

Coastal Flood — 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 to major coastal floodin...

Coastal Flood — Oct 2, 2025

Hurricanes Humberto and Imelda were located well offshore of the Eastern Seaboard on October 1, with high pressure over the Great Lakes and southern Canada. The combination of elevated winds and long-period swell led to coastal flooding. A few locations along the Virginia tidal rivers reached moderate flood stage from later October 1 into early October 3.

Coastal Flood — Nov 15, 2024

An area of low pressure moved across the Outer Banks and out to sea on the night of November 14 into November 15. Winds became northeast ahead of the low and northwest behind the low as it moved offshore on November 15. The result was a surge of water from the Chesapeake Bay with moderate coastal flooding reported across several areas.
