The National Weather Service (NWS) has issued multiple flash flood warnings across several counties in New York and Pennsylvania as heavy thunderstorms bring significant rainfall to the region. Residents are urged to take precautions as flash flooding is already occurring in some areas.
In a warning effective until 10:15 PM on May 5, 2025, the NWS in Binghamton alerted residents of Southwest Steuben County, New York, about thunderstorms producing heavy rain. As of 7:13 PM EDT, emergency management reported that between 0.5 and 1 inch of rain had already fallen, with flash flooding underway. The NWS cautioned, "Flash flooding means you need to turn around and don’t drown! It is going to be dark and you may not be able to see the hazards ahead." This warning serves as a critical reminder for drivers to avoid flooded roadways.
In Bradford County, Pennsylvania, a similar flash flood warning was issued until 10:30 PM on May 5, 2025. The NWS reported that between one and one and a half inches of rain had already fallen, leading to potential flooding in urban areas, highways, and small streams. Residents are advised to report any flooded areas to local emergency services, as this information helps the NWS monitor the situation.
As the evening progressed, the NWS extended its warnings to Adams, Cumberland, and Franklin counties. At 9:38 PM, Doppler radar indicated that thunderstorms were producing heavy rain, with rainfall amounts reaching between 1 and 2 inches. The NWS warned that additional rainfall of 1 to 2 inches was possible, and flash flooding was either ongoing or expected to begin shortly. Areas impacted include Waynesboro, Shippensburg, and several others. The NWS reiterated the importance of safety, urging residents to "Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles." This caution is especially pertinent at night when visibility is reduced.
In South-Central Pennsylvania, the NWS has specifically warned about the dangers of flash flooding in urban areas, highways, streets, and underpasses. Locations such as Guilford and Fayetteville are among those expected to experience severe weather conditions. The NWS highlighted that flash floods can develop rapidly, often within minutes to hours, and can occur even in areas not currently experiencing rainfall.
The warnings extend beyond Pennsylvania and New York. In Richmond, Virginia, the NWS in Wakefield issued a flood warning until 7 PM on May 5, 2025. Doppler radar indicated that thunderstorms were producing rainfall of about 1 to 1.5 inches, with an additional 1 to 2 inches possible. Affected areas include Chesterfield County and the cities of Colonial Heights and Petersburg. The NWS emphasized the need for caution, stating that most flood-related fatalities occur in vehicles.
As thunderstorms continue to move through the region, the NWS has provided essential safety guidelines for residents. These include moving to higher ground if in a flood-prone area, following evacuation orders when issued, and steering clear of flooded basements and submerged areas. The NWS advises against entering water that may carry an electrical charge and stresses the importance of not attempting to walk through floodwaters, as even six inches of fast-moving water can sweep individuals off their feet.
For those driving during heavy rainfall, the NWS recommends maintaining safe driving distances, slowing down, and being cautious of slippery roads. It is essential to avoid parking or walking near culverts or drainage ditches during heavy rain, as swift-moving water can pose significant danger. Additionally, drivers should enhance visibility by turning on headlights and should be particularly careful during the first half-hour after the rain begins, when the road surface can be particularly slick.
Residents in affected areas are encouraged to stay informed about weather conditions through local news outlets and the NWS. Utilizing resources such as the Eyewitness Interactive Radar can help individuals keep track of changing weather patterns and alerts. The NWS also urges people to heed advice from local authorities and to report any flooding incidents to help with emergency response efforts.
As the storms progress into the night, the potential for flash flooding remains a serious concern. With heavy rainfall already impacting several counties and more predicted, it is crucial for residents to remain vigilant and prepared. The NWS continues to monitor the situation and will provide updates as necessary to ensure public safety.
