Typhoon Warning, Malibu and Camp Pendleton fires, Edison power shutoffs; Canadian River flooding

Guam and Rota are under a Typhoon Warning as Tropical Storm Champi tracks toward the Marianas, with Guam in Condition of Readiness 2, the Joint Information Center partially activated and the Judicial Branch closed. In California, the Bryson Fire in Malibu and the Henderson Fire on Camp Pendleton prompted evacuations and a brief Interstate 5 closure while Southern California Edison de-energized more than 62,000 customers. Oklahoma faces moderate river flooding on the Canadian and North Fork Red rivers, a broad Red Flag Warning stretches from Texas through Mississippi, and CISA added an Atlassian vulnerability to its Known Exploited Vulnerabilities catalog with a federal remediation deadline this weekend. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. An EOC Voices podcast. Key Takeaways • Tropical Storm Champi: A Typhoon Warning covers Guam and Rota with typhoon force winds possible Sunday morning. Guam is in Condition of Readiness 2, courts are closed and fuel permit rules are temporarily waived, so response partners should expect compressed preparation timelines through Saturday. • Marianas flooding and surf: A Flood Watch runs through Sunday afternoon across Guam and the Northern Marianas, with 6 to 12 inches of rain forecast, surf to 26 feet on Guam reefs and coastal inundation to 5 feet, which puts low lying critical infrastructure and shoreline roads at risk. • Southern California fire weather: Evacuation orders and warnings are active for the Bryson Fire in Malibu, and forecasters warn of extreme fire behavior with any new start through Saturday across Los Angeles and Ventura counties. • Power shutoffs: Southern California Edison has 62,251 customers de-energized and 210,220 under consideration, a lifeline impact that affects medical baseline customers, traffic control and communications sites. • Camp Pendleton and Interstate 5: The Henderson Fire reached 1,404 acres and closed Interstate 5 between Harbor Drive and Basilone Road before reopening, a reminder that a single corridor closure can sever regional mutual aid routes. • Oklahoma river flooding: Moderate flooding is forecast on the Canadian River at Norman, Purcell, Mustang and Bridgeport, with warnings extending into Monday evening and the North Fork Red River raised from minor to moderate severity. • Multistate Red Flag event: Critically dry fuels, gusts to 35 mph and low humidity put Mississippi, Louisiana, Arkansas, southeast Oklahoma and east Texas under Red Flag Warnings, with outdoor burning discouraged. • Cyber remediation deadline: CISA added CVE-2026-21589 in multiple Atlassian products to the Known Exploited Vulnerabilities catalog with a remediation deadline of October 18, so agencies and critical infrastructure operators should confirm patch status this weekend. • Volcanic activity: Great Sitkin in Alaska and Kilauea in Hawaii both remain at Watch with an Orange aviation color code, with Kilauea’s summit highly pressurized and vent activity able to shift location. • Potable water: Boil water actions are in effect in the Copper Ridge subdivision served by New Braunfels Utilities in Texas and on several streets in West Columbia, South Carolina, both following water main breaks.
