Tornado watches or warnings were issued for 40 different counties Friday as severe weather struck the Midwest. Governor Reynolds has approved state assistance to six counties — Cedar, Clinton, Delaware, Johnson, Mahaska and Washington. Emergency shelters were opened in Coralville and Manchester. Damage was reported near Ottumwa and in Keokuk County as well. About half of the residents in Charlotte, a small town in Clinton County, were evacuated because a propane tank was damaged and began leaking. The storm system knocked out electricity to thousands of customers in Iowa on Friday afternoon and, by midnight, snow had begun falling in northwest Iowa.
