ST. LOUIS (AP) -- Utility crews across Illinois appear to be making progress restoring electricity to nearly 90,000 homes and businesses left in the dark as a result of the winter storm that barreled through the nation's midsection.
ComEd says that more than 60,000 of its northern Illinois customers, mostly around Chicago, were without electricity as of Wednesday's morning rush-hour.
St. Louis-based Ameren says that as of shortly after 8 a.m. Wednesday, more than 28,000 of its customers were without electricity. Those outages stretched from around Peoria south to Chester, just southeast of St. Louis.
Ameren says the leading cause of outages is when strong winds blow across ice-covered power lines, causing those lines to bounce violently and strike each other.
People are urged to report downed power lines.
