MARYLAND — Most of Maryland is under a severe thunderstorm watch Monday until 10 p.m., with large hail and damaging winds seen as the main threats, the National Weather Service said.

Seventeen counties, plus the city of Baltimore, are under the watch. They are: Anne Arundel, Baltimore, Calvert, Caroline, Charles, Dorchester, Harford, Howard, Kent, Montgomery, Prince George's, Queen Anne's, Somerset, St. Marys, Talbot, Wicomico and Worcester counties.
