A catastrophic flash flood emergency is unfolding in southeastern Missouri as heavy rains, described as a 1-in-1,000-year event, have led to widespread flooding and dangerous conditions across the region. Authorities have rescued at least 100 individuals, with ongoing efforts to locate approximately 17 missing people, including campers trapped in trees after a building at a campground in Reynolds County collapsed into floodwaters. The situation remains critical, with a state of emergency declared by the governor as more rain is expected. As rescuers continue their work, many roads are closed, homes are evacuated, and swift water rescue teams are being deployed to assist with ongoing operations in the affected areas.
