Ameren spokesman Tim Fox says about 38,000 Illinois customers of the St. Louis-based utility are without power. And there's no word yet on when the power might be restored.
Sunday’s storm killed 54-year-old Delancey Moore of East St. Louis. Authorities say he died when part of a clothing store's roof collapsed in Fairview Heights.
Clean-up continues in that hard-hit Metro East, where an apartment building's roof and one of its sides were blown away. No injuries resulted from that.
Schools are closed in Champaign due to power outages there.
