Heavy Rainfall of 2–4 Inches Per Hour Creates Life-Threatening Flash Flooding Across Parts of North Carolina and Virginia
A Flash Flood Warning has been issued for portions of North Carolina and Virginia, including Alleghany County (NC), Ashe County (NC), Carroll County (VA), the City of Galax (VA), Grayson County (VA), Smyth County (VA), and Wythe County (VA). Torrential thunderstorms are capable of producing 2 to 4 inches of rainfall in just one hour, creating an extremely dangerous flash flood situation.
Residents should prepare for rapidly rising creeks and streams, flooded roads, and dangerous travel conditions. Flash flooding can develop with little warning, especially in mountainous terrain and low-lying areas.
Areas Under the Flash Flood Warning
The warning includes:
- Alleghany County, North Carolina
- Ashe County, North Carolina
- Carroll County, Virginia
- City of Galax, Virginia
- Grayson County, Virginia
- Smyth County, Virginia
- Wythe County, Virginia
Heavy rainfall rates of 2 to 4 inches per hour may quickly overwhelm drainage systems, leading to significant flooding in urban areas, valleys, and along small streams.
What to Expect
Strong thunderstorms are expected to continue producing intense rainfall capable of causing:
- Rapid flash flooding
- Flooded roadways and intersections
- Rising creeks and streams
- Water covering bridges and low-water crossings
- Mudslides or rockslides in steep terrain
- Hazardous travel conditions with reduced visibility
Floodwaters can rise within minutes, making roads unsafe even if they appeared clear moments earlier.
Flash Flood Safety Tips
If you are in the warning area:
- Never drive through flooded roads. Just a small amount of moving water can carry away a vehicle.
- Move immediately to higher ground if flooding begins.
- Stay away from creeks, streams, drainage ditches, and rivers.
- Avoid walking through floodwaters, which may contain hidden hazards or swift currents.
- Continue monitoring weather alerts and emergency information until the warning expires.
Stay Weather Aware
Additional thunderstorms may continue to produce heavy rainfall throughout the day. If new rounds of storms develop over the same locations, flooding conditions could worsen quickly.
Residents across northwestern North Carolina and southwestern Virginia should remain alert, have multiple ways to receive weather warnings, and be prepared to act immediately if conditions deteriorate.
