How Accomack County floods

Accomack County experiences a flood risk profile dominated by flash flooding and coastal flooding. Over the past 30 years, NOAA recorded 23 flash flood events and 19 coastal flood events, alongside 7 tropical storms, 4 hurricanes resulting in 2 deaths, and 4 general flood events resulting in 1 death.

Recent events illustrate these varied hazards. On October 12, 2025, a coastal low combined with high pressure to generate strong northeast winds, causing widespread moderate to major coastal flooding across the Virginia Eastern Shore. Earlier that year, on August 19, 2025, slow-moving showers driven by moist easterly flow and a weak surface low produced areas of flash flooding during morning hours.

National Flood Insurance Program claims data demonstrates that risk is heavily concentrated in specific zones. Zone A accounts for the vast majority of claims with 988 filings, averaging $14,104 per payout and an average recorded water depth of 6 inches. Zone V properties experienced 63 claims with an average payout of $24,877 and an average recorded water depth of 6 inches. Properties located in Zone A and Zone V should pay the closest attention to flood risk, alongside limited claims in Zone X (19 claims, average 9 inches recorded water depth), Zone X_SHADED (13 claims, average 3 inches recorded water depth), and unknown zones (22 claims, average 2 inches recorded water depth).

Where the flood claims came from

2% of Accomack County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

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 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.

Flash Flood · Aug 19, 2025. A weak trough aloft and weak surface low were located in the vicinity of southeast Virginia on August 19. Moist, easterly flow led to widespread showers with localized higher rainfall rates; the slow-moving showers on the Virginia Eastern Shore produced areas of flash flooding in the morning hours.

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 flooding across eastern Vir…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Accomack County

If a building in Accomack County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
