CEDAR RAPIDS, Iowa — Two rounds of thunderstorms moved through Eastern Iowa on Monday afternoon and evening, bringing large hail and then strong winds and a couple possible tornadoes.
The first system moved up from southeast Iowa near Washington through Anamosa. Several reports of hail as large as golf balls came in from the strongest thunderstorms. That activity moved across the Mississippi River and out of the TV9 viewing area.
Starting about 7:15 p.m., the National Weather Service issued the first of multiple tornado warnings for storms moving in from Nebraska and Minnesota. Wind gusts between 50 and 70 miles per hour were common.
The Butler County Sheriff’s Office said Clarksville was “hit bad” and urged people there to remain inside while cleanup continued. Fayette County Emergency Management Coordinator Mike Foland reported widespread damage along 100th Street throughout the county.
Tornado warnings continued until about 10:45 p.m. when the last one expired for Linn County.
Flooded streets were reported in Waterloo, Cedar Rapids and other cities and towns in eastern Iowa. Flash flood warnings in effect for Grundy, Hardin and Franklin counties are set to expire at early Tuesday morning. The National Weather Service had not indicated as of 11:45 p.m. Monday if it would add additional counties to that list.
