Flash Flood Warning Issued for New Jersey and Pennsylvania
Residents across southeastern Pennsylvania and southern New Jersey should take immediate precautions as a Flash Flood Warning remains in effect for Bucks, Delaware, Montgomery, and Philadelphia counties in Pennsylvania, as well as Burlington, Camden, and Gloucester counties in New Jersey. Torrential rainfall has created dangerous flooding conditions capable of overwhelming roadways, small streams, creeks, and low-lying urban areas.
According to the National Weather Service, radar has detected intense thunderstorms producing rainfall rates capable of causing flash flooding with little warning. Many neighborhoods have already received several inches of rain, increasing the risk of rapidly rising water and hazardous travel conditions.
Areas Included in the Flash Flood Warning
Pennsylvania
- Bucks County
- Delaware County
- Montgomery County
- Philadelphia County
New Jersey
- Burlington County
- Camden County
- Gloucester County
Motorists should expect flooded intersections, highway ponding, and reduced visibility during periods of heavy rain. Urban areas are especially vulnerable as storm drains become overwhelmed by excessive rainfall.
Greatest Hazards
Residents should prepare for:
- Rapid flooding of streets and highways
- Flooded underpasses and low-water crossings
- Overflowing creeks and streams
- Water entering homes and businesses in flood-prone locations
- Hazardous driving conditions with limited visibility
- Possible power outages from severe thunderstorms accompanying the heavy rain
Flash Flood Safety Tips
If you are within the warning area:
- Never drive through flooded roadways.
- Turn Around, Don’t Drown®—just a small amount of moving water can sweep away a vehicle.
- Move immediately to higher ground if flooding begins.
- Stay informed by monitoring local weather alerts.
- Keep phones charged and have emergency supplies ready.
- Avoid walking through floodwaters, which may hide debris or electrical hazards.
Stay Alert
Additional rounds of showers and thunderstorms may continue across the Philadelphia metropolitan region, meaning flooding conditions can worsen quickly even after rainfall temporarily decreases. Residents throughout southeastern Pennsylvania and southern New Jersey should remain weather aware until the Flash Flood Warning expires and local officials declare conditions safe.
