Preliminary Local Storm Report
National Weather Service Twin Cities/Chanhassen MN
252 PM CDT Wed Apr 23 2025

Widespread rainfall expected across central Iowa (80-90%) Thursday continues to signal an increasing potential for additional rainfall totals around an inch, with an isolated higher amount near 1.5’’ across central and northern Iowa. River responses per HEFS guidance suggests that a rise above Action Stage is likely (70-90%) at Shell Rock and Cedar Rivers Thursday into Friday. Though the likelihood for additional sites to see river flow exceedance is on the lower end (<=30) at the Iowa River, Des Moines River, and Raccoon River, rises at and above the Action Stage threshold if higher rainfall amounts were to occur. Close monitoring will continue to watch for this potential.
