"Over the past 24 hours, intense storms have created dangerous flash flooding across several regions of Missouri, resulting in multiple swift-water rescues. Activating the State Emergency Operations Plan allows our agencies to move quickly, coordinate resources, and support local response efforts," Gov. Mike Kehoe said in a statement Friday. "With additional heavy rain expected through the weekend, the threat is not over. If you're camping, floating, or spending time near rivers and streams, move to higher ground and stay alert of weather conditions," Kehoe said.
