Des Moines, IA – Central Iowa is bracing for a soggy and turbulent week as multiple rounds of thunderstorms are expected to move through the region, bringing the potential for severe weather and localized flooding. The activity begins Monday and is likely to persist through much of the workweek, impacting travel and outdoor plans ahead of the Juneteenth holiday.
According to the National Weather Service in Des Moines, a hazardous weather outlook has been issued for a large portion of central Iowa, including Polk, Dallas, Jasper, and Warren counties. The primary threats from these recurring storms include periods of heavy rainfall, which could lead to flash flooding, hail, and gusty winds. River rises are also possible as the week progresses.
The stormy pattern kicks off Monday with a 40 percent chance of showers and thunderstorms, primarily after 7 a.m. Conditions will intensify Tuesday, when heavy rain becomes more probable after 1 p.m., potentially snarling traffic along I-35 and I-80. Showers and thunderstorms are expected to deliver between one and two inches of rain Tuesday night alone.
Residents should take precautions by ensuring storm drains are clear of debris to mitigate street flooding. Having multiple ways to receive weather alerts is advised, as conditions could change rapidly. Officials remind the public to never drive into flooded roadways. While widespread thunderstorm activity is the main concern, a brief break in the rain may arrive in time for Juneteenth.
Weather spotter activation may be needed this week as the systems move through. Warnings will remain in effect as the situation develops.
