Central U.S. Flooding Triggers Water Rescues as Heat Builds; Red Flag Warnings Span the Southwest; CISA Flags Two Actively Exploited Vulnerabilities

A slow-moving storm system drove roughly two dozen flash floods and water rescues across Arkansas, Kansas, Missouri, and Oklahoma on June 8, with flood watches stretching into the Tennessee Valley and severe storms threatening the central Plains. Heat advisories take hold June 9 across parts of the Mid-South as a broader heat wave builds. Red Flag Warnings cover southern Nevada, northwestern Arizona, and much of Utah, with the national preparedness level at 2 and six uncontained large fires burning. CISA added two actively exploited vulnerabilities, in BerriAI LiteLLM and Check Point Security Gateway, to its Known Exploited Vulnerabilities catalog. State updates include the Sorrento Fire evacuations in San Diego, a command transition on New Mexico’s Seven Cabins Fire, and a lifted boil water advisory in West Columbia, South Carolina.
