Des Moines, Iowa – Severe storms will threaten much of Iowa Monday evening, bringing the risk of tornadoes, damaging winds, and very large hail to cities including Des Moines, Ames, and Waterloo from 4 p.m. until midnight.
According to the National Weather Service in Des Moines, a widespread severe weather outbreak is expected with an enhanced risk zone stretching south of Highway 20. The primary threats include tornadoes—some potentially strong—hail up to 2 inches or larger, and wind gusts over 60 mph, especially north of US-20. Storms are forecast to develop rapidly late in the afternoon, leaving little time for residents to react.
Central counties such as Story, Polk, and Black Hawk face the greatest risk, with schools and commuters urged to monitor alerts closely. Outdoor events should be postponed, and those in mobile homes or temporary structures are encouraged to seek sturdier shelter before storms arrive. Power outages and tree damage are likely if the most intense cells track across major corridors like I-35 and I-80.
This is the region’s highest severe weather risk so far this spring, echoing similar outbreaks in recent years. Additional watches or warnings may be issued through the night, and residents should stay tuned for further updates from local officials. Severe threats may persist into early Tuesday.
