Flash flooding from slow-moving thunderstorms is the dominant flood character in Warren County. Between 2025 and 2055, NOAA Storm Events data recorded 70 flood events and 45 flash flood events. For example, a slow-moving storm system brought localized rainfall of four to eight inches to the Blue Ridge in May 2025, causing flooding that lingered into the next morning. In July 2025, an unusually moist airmass contributed to slow-moving thunderstorms that produced two to five inches of rain, leading to flash flooding.
NFIP claims data shows that properties in Zone A experienced an average of 6.4 feet of water depth with an average payout of $19,588. Claims in Zone X_SHADED also indicate significant water depth, averaging 6.7 feet with a higher average payout of $22,992.

Flood — Jul 19, 2025
An unstable atmosphere along with plenty of moisture led to the development of showers and thunderstorms. The thunderstorms were slow moving, and trained over the same areas in spots resulting in flash flooding. Localized rainfall totals of 2 to 4 inches were observed, with upwards of 5 inches in the most persistent thunderstorms.
Flash Flood — Jul 16, 2025
An anomalously moist airmass with tropical moisture resided over much of Virginia on July 16th. This comes after several days of showers and thunderstorms, which left some areas with suppressed flash flood guidance. Slow moving thunderstorms developed on remnant boundaries and terrain circulations before propagating eastward. These storms produced localized rainfall amounts of two to five inches.
Flash Flood — Jun 14, 2025
A weak area of low pressure interacted with an anomalously moist airmass and stalled frontal boundary. This spawned showers and thunderstorms that resulted in localized amounts of one to five inches of rain. The higher amounts were where storms trained or stalled.
Flash Flood — Jul 14, 2025
Another day of an anomalously moist airmass produced numerous showers and thunderstorms across Virginia. This resulted in localized rainfall amounts of 2 to 4 inches in a short period of time, which resulted in instances of flooding and flash flooding.
