On the one-year anniversary of the derecho that ripped through Iowa, meteorologist Terry Swails joins the DMPL Podcast to talk about Swails' newest book, Derecho 911. During the podcast, Swails recalls the events of that day and discusses what makes derechos so hard to predict.

He also talks about the aftermath, including the damage, how communities came together, and what steps the National Weather Service is taking in the future to ensure people are as prepared as possible for sudden severe weather events.
