Overview

  • The fire is mapped at roughly 6,803 acres with containment reported at about 21% and more than 2,700 personnel and heavy equipment assigned.
  • Public health officer Christine Wu declared a local health emergency citing toxic debris and increased turbidity affecting local water systems.
  • The Board of Supervisors ratified both the health emergency and a broader local emergency signed by CEO Ryan Alsop, with the general declaration awaiting the governor’s signature.
  • Evacuation orders were downgraded to warnings in some zones near Calistoga while several zones remain under orders, and officials report no injuries or deaths.
  • Officials tallied more than 287,000 gallons of retardant and over a million gallons of water dropped as a regional smoke advisory continues, and the cause remains under investigation with dispatch audio suggesting an unconfirmed “escaped control burn.”
