Winter emergencies in Maryland
Maryland's cold winters bring waves of emergency calls during the first deep freeze and every arctic front after it. Expect longer waits during regional cold snaps. Calling early, when the house first starts losing heat, helps.
Western Maryland gets mountain snow, while the Baltimore-Washington corridor deals with ice and quick freezes.
