Flash Flood Warning for Alleghany and Surry Counties, North Carolina
A Flash Flood Warning has been issued for Alleghany County and Surry County, North Carolina, where flooding has been observed and continues to pose a threat to residents and travelers. The warning is based on observed flooding, indicating that dangerous flash flooding is already occurring or imminent in portions of the warned area.
Rainfall rates are currently estimated between 0.25 and 1 inch per hour, which may continue to produce rapid runoff, especially in low-lying areas, small streams, creeks, and locations with poor drainage.
Flooding Already Observed
Unlike warnings based solely on radar estimates, this alert is classified as Source: Observed, meaning emergency officials or trained weather spotters have confirmed flooding conditions.
Residents in the affected counties should remain alert for:
- Flooded roads and highways
- Rising creeks and streams
- Water covering low-water crossings
- Rapid flooding in poor drainage areas
- Dangerous travel conditions, especially during heavy rain
Safety Tips During a Flash Flood Warning
If you are in Alleghany or Surry County:
- Never drive through flooded roadways. Just a few inches of moving water can sweep away a vehicle.
- Move to higher ground immediately if flooding threatens your location.
- Stay away from creeks, rivers, and drainage ditches.
- Monitor NOAA Weather Radio, local officials, and trusted weather sources for updates.
- Be prepared for changing conditions if additional rainfall develops.
North Carolina Flood Risk
The mountainous and foothill terrain of northwestern North Carolina allows water to collect quickly during prolonged rainfall. Even moderate rainfall rates between 0.25 and 1 inch per hour can result in localized flash flooding where soils are saturated or drainage systems become overwhelmed.
Motorists should use extra caution, particularly on rural roads where flooding may not be immediately visible.
Continue Monitoring Conditions
The Flash Flood Warning will remain in effect until conditions improve or the National Weather Service determines the flooding threat has ended. Residents should continue monitoring official forecasts and avoid unnecessary travel until waters recede.
