ANNAPOLIS, Md. (AP) — Gov. Martin O’Malley is urging state residents to be careful in the heat in the aftermath of a storm that knocked out power to more than 895,000 Marylanders and killed at least one person.

The governor called Friday night’s storm a “very historic event” and a “violent and dangerous storm.”

He says the damage is combining with high heat to pose problems for residents.

He also warned that storm fronts as violent as Friday’s weather could reach Maryland about 4 p.m. Saturday.

During a briefing Saturday by O’Malley and other state officials, the head of the Maryland Department of Natural Resources said one person is missing after a boat capsized near Chesapeake Beach during the storm. Four others who were on the boat are accounted for.
