The National Weather Service in Des Moines is warning of heavy rain and storms moving into central Iowa this morning, with the highest chances of rain and storms expected between 9 AM and 3 PM. Many locations, including Des Moines, Ames, Fort Dodge, and Marshalltown, face rain probabilities between 70 and 80 percent during that window, leading to the potential for slick roads, reduced visibility, and standing water.

Why it matters

This intense weather system could create hazardous driving conditions during the busy morning and midday commute times, potentially leading to delays, accidents, and disruptions for residents and businesses across the region. The heavy rainfall also raises the risk of flooding in low-lying or poorly drained areas.

The details

The rain is already spreading across central Iowa this morning and is expected to worsen quickly. Roads along major interstates like I-35 and I-80, as well as U.S. 69, could become slick with reduced visibility during the heavier downpours. Drivers should allow extra travel time and watch for standing water, especially in low-lying or poorly drained areas. By mid to late afternoon, the rain coverage is expected to taper off, shifting to more scattered showers. However, additional storm development is possible overnight, with a few stronger storms potentially producing small hail.
