Flash Flood Warning Issued for Martinsville, Henry and Pittsylvania, Virginia – July 22, 2026
A Flash Flood Warning has been issued for the City of Martinsville, Henry County, and Pittsylvania County, Virginia, on July 22, 2026, as heavy thunderstorms continue to produce excessive rainfall across Southside Virginia. The National Weather Service warns that rapidly rising water may create dangerous conditions on roads, near creeks, streams, and other flood-prone locations.
Residents should be prepared for rapidly changing weather conditions as intense rainfall can overwhelm drainage systems in a short amount of time. Low-lying areas, urban streets, and locations near rivers and streams are especially vulnerable to flash flooding.
Areas Under the Flash Flood Warning
The warning includes:
- City of Martinsville
- Henry County
- Pittsylvania County
Heavy rainfall may lead to flooded roadways, overflowing creeks, and hazardous travel conditions throughout the region. Motorists are encouraged to avoid unnecessary travel until the threat has passed.
Flooding Concerns Continue Across Southern Virginia
The current weather pattern has brought repeated rounds of thunderstorms across Virginia, leaving the ground saturated and increasing the likelihood of flash flooding. Additional rainfall may quickly worsen conditions, especially in locations that have already received heavy precipitation.
Residents living near the Smith River and smaller tributaries should closely monitor water levels as localized flooding can develop with little warning.
Flash Flood Safety Tips
During a Flash Flood Warning:
- Never drive through flooded roadways.
- Turn Around, Don’t Drown®—just a few inches of moving water can sweep away a vehicle.
- Move immediately to higher ground if flooding develops.
- Stay away from creeks, rivers, and drainage ditches.
- Monitor local weather alerts for updates and possible warning extensions.
- Keep an emergency kit and charged mobile devices ready.
Stay Weather Aware
