A map from AccuWeather warned that the highest-risk areas for flash flooding are Southern New Jersey, Southeastern Pennsylvania, Delaware, much of Maryland, Eastern and Central Virginia and Northern North Carolina. Downpours associated with the storms could be severe enough to cause travel disruptions and flash floods, the map said.

Flash flooding from heavy rain killed at least three people and prompted dozens of rescues in the Ruidoso area of southern New Mexico, officials said — the same area devastated by wildfires last year.
