A “large and extremely dangerous tornado” touched down in eastern Iowa on Thursday evening, the National Weather Service reports, calling for Midwest communities to take caution as severe weather moved across the region.
The agency said the tornado was seen near Camanche at 6:45 p.m. ET and moving northeast at 40 mph. CNN reports the twister is one part of a severe weather system that could effect up to 95 million people on Thursday, notably in cities like St. Louis and Chicago.
The National Weather Service said Thursday that Chicago and much of central and northeastern Illinois would be under a tornado watch until 11 p.m. CT (midnight ET). A tornado was spotted earlier in the day in Illinois, and tornado watches are in effect for parts of nine other states, Weather.com reports.
