A mother, her two children and their dog needed to be rescued from a car when heavy downpours caused floodwaters to overcome a street in Chester County. A local photographer shared images and video of the rescue that happened on South Bailey Road near Lincoln Highway in Caln Township on Thursday afternoon. A Pennsylvania State Trooper and a young witness waded through knee-high floodwaters to reach the stranded family of four. Firefighters from Thorndale Township Fire Department helped another family whose van became waterlogged during Thursday afternoon's drenching rain.
