Overview
- The storms that swept the Mid‑Atlantic Thursday produced confirmed tornadoes, widespread urban flash flooding in New York City and at least one lightning death on a Virginia beach.
- Intense rain rates of up to 2–3 inches per hour overwhelmed drains and closed major roadways and subway stations in New York while the FAA issued ground delays at JFK, LaGuardia and Newark.
- Local authorities reported structural damage, power outages and declared states of emergency in places such as Dover, Delaware and Columbia Borough, Pennsylvania following tornado strikes.
- Forecast centers show the heavy‑rain threat moving south into North and South Carolina with a Level 2 severe risk and continued flash‑flood watches that could affect Philadelphia and Washington, D.C., later in the weekend.
- Urban flooding rises so fast because paved surfaces force water into drains that cannot handle very high rainfall rates, which raises the risk of stranded vehicles, lasting power outages and prolonged travel disruption.
