Early on June 5, an alert was issued in Charles County, which was quickly followed up across the state, according to the National Weather Service.
Forecasters say that "those in the direct path of a tornado touchdown, flying debris will be dangerous to those caught without shelter.
"Damage to roofs, siding, and windows may occur. Mobile homes may be damaged or destroyed."
Tree damage is also likely, and some areas may see pea-sized hail.
"Take cover now," the warning states. "Move to a basement or an interior room on the lowest floor of a sturdy building.
"Avoid windows. If you are outdoors, in a mobile home, or in a vehicle, move to the closest substantial shelter and protect yourself from flying debris."
