Back-to-back flooding disasters in recent years — in Texas, New Mexico and Kentucky, among many others — have showed that preparing for flash flooding is a new necessity as the planet warms.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

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.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River and others rose rapidly.

Major I-95 cities -- Philadelphia, Baltimore, Washington, D.C., and Richmond, Virginia -- could be impacted as heavy downpours could bring 2-3 inches of rainfall per hour over already saturated soils, which could easily cause flash flooding.
