At least three tornadoes hit southern Maryland as Tropical Storm Isaias blew through the Chesapeake Bay and D.C. area on Tuesday morning, killing one person in Maryland and causing significant flooding and damage, the National Weather Service confirmed.

Two touched down in St. Mary's County and another spun through Calvert County.

A trained storm spotter reported seeing one tornado in Leonardtown as the storm raged in St. Mary’s County early Tuesday.

The second tornado confirmed hit Chesapeake Beach in Calvert County.

There, one family told News4 that a severe weather alert spurred them to leave an upstairs bedroom. Fifteen minutes later, a tree smashed through the roof and into that room.

Another woman told six or seven trees fell on her property.

The National Weather Service says it will release more detailed reports on Wednesday.

Isaias has blown north up the Atlantic Coast and away from the Chesapeake Bay, but communities are still coping with flooding and damage in its wake.

As of 7:30 a.m. Wednesday, 4,500 SMECO power customers still were waiting for the electricity to get turned back on, mostly in Charles and Calvert Counties.

Closer to the D.C. area, Prince George's County had dozens of power outages on Wednesday morning and remained under a flood warning until 9:30 a.m.

St. Mary's County declared a state of emergency through Tuesday to help coordinate a massive clean up response. Several roads were still closed Tuesday morning. Here's the county's full list.

Confirmed Tornado Leaves Behind Major Damage in Calvert County

The county was inundated with heavy downpours that dumped 9 inches of rain at Sotterly and 5 inches of rain in California.

One person was killed in Mechanicscville when a tree fell onto their moving car.

At least five people were rescued nera Budds Creek Road, near Colton Point Road, when high water rapidly overtook the road. One person was rescued after their car became stalled in a flooded street, the Seventh District Volunteer Fire Department said.


Firefighters rushed back to the same area after bystanders reported seeing a car swept away. Two civilians who tried to help were rescued from the waters. Two occupants in a car were also pulled into a rescue boat.

Chaptico is one of many communities in Saint Mary's dealing with lingering flooding on Tuesday.

News4 spoke with two residents who say they’ve lived in Saint Mary's County all their lives and have never seen anything like this.

"This is just unbelievable," said resident Wanda Smith. "I've never experienced anything like this before. This is just chaotic."

"Never in my life in St. Mary's County have I ever seen this. And I hope I never see it again," Janice Jones said.
