Heavy Rain and Flash Flooding in the West; Heat Expands in the Central U.S.

Monsoonal moisture will produce showers and thunderstorms with heavy rain over parts of the Southwest, Great Basin, and Central Rockies through Monday. Flash flooding is possible, especially in and around burn scars and in areas of steep terrain. Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >

Due to the ongoing COVID-19 concerns and the call of social distancing by the Center for Disease Control and Prevention, the National Weather Service (NWS) is canceling Iowa's 2020 tornado drill originally scheduled for 10 AM on Wednesday, March 25th.  Most sheltering locations are in confined spaces, which is not where people should be congregating given ongoing concerns. Another group that we focus on practicing their sheltering is schools and with the majority of those now out of session for the next 4 weeks, the outcome is ineffective.  Aside from the tornado drill cancellation, Severe Weather Awareness Week will continue as normal next week, where Iowa NWS Offices and the Iowa Homeland Security and Emergency Management will provide safety reminders as severe weather season 2020 is right around the corner.  We are asking Iowans to spend a few minutes next week thinking about & discussing their in-home severe weather sheltering plans.  Check back for additional preparedness information next week at the following Iowa serving NWS office websites and social media channels...
