Northumberland County Flood History

Coastal Flood — Oct 29, 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 22, 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 — May 21, 2025

An area of low pressure occluded over the Ohio Valley on May 21 into May 22. This allowed for a period of elevated onshore flow which led to moderate coastal flooding across portions of eastern Virginia along both sides of the Chesapeake Bay on May 21 and 22.

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 1, 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.
