Wind-driven wildfires dominate today’s brief, with the Sandy Fire in Ventura County, California pushing more than 43,000 residents out of Simi Valley and the Seven Cabins Fire in New Mexico growing to nearly 16,000 acres with no containment. In the Plains and Midwest, Auburn, Nebraska issues a disaster declaration after Monday’s straight-line winds and flooding, and Evergy reports a peak of about 64,000 outages across the Kansas City metro. CISA releases five new ICS advisories and continues federal remediation pressure on KEV additions affecting Cisco SD-WAN and Linux. The CDC’s Bundibugyo Ebola HAN remains active for clinician awareness. EM Morning Brief is your concise daily update on national and state-by-state emergency management news.
