Weather service investigates possible Md. tornado

      JARRETTSVILLE, Md. (AP) - Storms that swept through Harford County have left downed trees and power lines after reports of a possible tornado.

      The fast-moving storm along the Interstate 83 corridor prompted a tornado warning on Friday night.

      Emergency workers were called to the Jarrettsville area after residents reported downed damage along a 100-foot-wide path near Salem Church and Cox roads.

      Harford County officials said Saturday that no injuries were reported as a result of the storm.

      The National Weather Service says it's investigating the damage to determine whether a tornado can be confirmed.

      Hundreds of power outages were reported Friday night in Baltimore County, Harford County, Howard County and Baltimore City.
