Today’s brief leads with post-tropical cyclone Arthur, which is pushing life-threatening flash flooding across Louisiana, Mississippi, Alabama, and the Florida Panhandle, with high-water rescues already underway in St. Tammany Parish. A separate severe-weather outbreak spawned tornadoes and damaging winds across Iowa, Illinois, Indiana, Kentucky, and Ohio, while weather-driven FAA ground stops snarled major airline hubs. We also cover active wildfires in California, New Mexico, and Arizona, a magnitude 4.5 earthquake near Pahala on Hawaii Island, Kilauea’s paused summit eruption, and a precautionary boil water notice in Pinellas Park, Florida. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast.
