Ongoing Outlook

Containment Projections: Firefighters expect to continue making steady progress toward full containment. With the fire currently at 80% containment, crews are focused on mop-up, patrol operations, and fire suppression repair. The improved black line around the perimeter has significantly reduced the threat of the fire spreading further.
Weather and Wind Warnings: Hot and dry conditions are forecast to persist in Lassen County, with temperatures reaching the upper 90s and relative humidity dropping into the low teens. There is also a slight chance of thunderstorms with breezy southwest to west winds. Firefighters remain vigilant as these dry conditions and potential winds increase the potential for residual heat to become active.

Cause and the Role of Weather and Climate

Cause: The cause of the Loomis Fire remains under investigation.
Weather and Climate: Extreme summer climate conditions played a significant role in the fire's initial behavior. Over the last 72 hours, the weather has brought hot, dry conditions with relative humidity dropping into the low teens. Dry grasses and other light vegetation remain highly susceptible to fire activity. These conditions heighten the risk of residual heat flaring up, requiring firefighters to remain especially vigilant in identifying and fully extinguishing any smoldering areas.
