Heavy Rain Triggers Dangerous Flash Flooding Across Parts of Western New York
Residents in portions of Allegany County and Cattaraugus County, New York, are under a Flash Flood Warning after heavy rainfall produced rapidly rising water on roads, small streams, and low-lying areas. The National Weather Service issued the warning as intense rainfall continues to create hazardous travel conditions and the potential for life-threatening flooding.
Flash flooding can develop with little warning, especially in hilly terrain where water runs off quickly. Even areas that are not typically prone to flooding can become dangerous during periods of intense rainfall.
Areas Impacted
The warning includes portions of:
- Southwestern Allegany County
- Southeastern Cattaraugus County
Heavy downpours are expected to continue producing rapid rises on creeks, streams, and poor drainage areas through the duration of the warning.
What to Expect
Residents may experience:
- Flooded roadways and intersections
- Rising creeks and small streams
- Water covering low-water crossings
- Rapid flooding in urban and rural locations
- Reduced visibility during heavy rainfall
Motorists should expect changing road conditions and be prepared for temporary road closures.
Flash Flood Safety Tips
Your safety should remain the top priority during a flash flood warning.
- Never drive through flooded roadways. Just a small amount of moving water can carry away a vehicle.
- Move immediately to higher ground if flooding develops near your location.
- Stay away from creeks, streams, drainage ditches, and floodwaters.
- Follow instructions from local emergency management and law enforcement.
- Continue monitoring weather alerts until the warning expires.
