A 12-year-old boy who was swept away by rushing water is believed to have been found dead after flash flooding impacted the Mid-Atlantic, authorities said Wednesday.

Flooding was reported in several states, including Pennsylvania, Maryland, Virginia and West Virginia, from a massive storm system.

As residents in Allegany County continue to recover from flash flooding that occurred on May 13, the Maryland Office of the Comptroller is offering assistance to help businesses that were affected.

Rising water levels led to dozens of rescues and the evacuation of an elementary school. A boy in Virginia was found dead after being swept away by floodwaters, officials said.

Parts of the Southeast and Mid-Atlantic were slammed with multiple inches rain, triggering flooding across multiple states.

A flash flooding emergency was declared by the National Weather Service for parts of western Maryland Tuesday and footage from a fire station in that area showed exactly what was in store.

The body of a 12-year-old boy has been found after he was swept away by rushing water on a Virginia roadway, while a dozen students stayed overnight at a Maryland high school as heavy rains led to flooding in several states, officials said.

Downpours spark floods in Maryland, Virginia and Pennsylvania, leaving one boy missing and forcing dozens to evacuate inundated homes and schools.
