Flash flooding struck Maryland after intense storms dropped up to six inches of rain.
Streets were submerged, trees were downed, and creeks overflowed, prompting a Flash Flood Emergency from the National Weather Service.
Residents were urged to avoid driving through floodwaters as dangerous conditions persisted.
Around 200 people were rescued from a Maryland elementary school using boats as floodwaters surged to the second floor.
Meanwhile, neighbouring areas in Virginia also issued flash flood warnings, with first responders searching for a 12-year-old boy swept away by the floods.
