A severe thunderstorm watch remained in effect for Baltimore and surrounding counties about 6:15 p.m. Tuesday after a previous warning was lifted, according to the National Weather Service.

The watch is in effect for Baltimore, Baltimore County and Anne Arundel County through 8 p.m.

The storm was moving southeast at 30 mph and is capable of producing hail the size of quarters and winds up to 60 mph, NWS said. Affected areas could include Towson, Parkville, White Marsh, Morgan State University, Carney, Homeland, Perry Hall, Rossville and Rosedale.
