“The traditional areas flooded right away and then some other areas too,” Cameron said.
One person was killed in St. Mary's County when a large tree toppled onto a moving car. Deputies from the St. Mary’s County Sheriff’s Office responded to the 29500 block of Three Notch Road in Mechanicsville at about 9:30 a.m. A huge tree fell onto the car’s roof, trapping the driver. The driver was pronounced dead at the scene. Their identity is being withheld pending notification of their family.
Cameron warned that roadways became "impassable and dangerous" and that multiple people needed to be rescued from high water.
