Officials have cautioned that dry conditions combined with strong winds could lead to a rapid increase in wildfire activity, particularly as a significant fire scorched nearly 3,500 acres in Mendocino County.
The National Weather Service has issued a “red flag warning” effective Saturday at 11 a.m. until Monday at 11 a.m., highlighting the risks associated with winds and low humidity that can make “easier fire starts” and promote “rapid fire spread.”
This warning comes as the Lucas Fire burns near the boundaries of Lake and Mendocino Counties in Potter Valley, prompting evacuation orders in various regions, according to CalFire.
The fire initially started as a small 10-acre blaze on Thursday but quickly grew in size due to its remote setting.
CalFire noted in an update on Friday evening that “Firefighters faced high temperatures and strong winds on the fire line today, working in challenging conditions to protect communities and slow the fire’s spread.”
Numerous evacuation orders have been issued for the surrounding areas, with the Lake County Fairgrounds designated as an official shelter for evacuees.
A portion of the Upper Lake Ranger District in the Mendocino National Forest was closed around 3 p.m. on Friday due to the fire’s proximity.
As of Saturday morning, the fire was reported to be 15% contained. Meanwhile, two additional wildfires, the Timber and Plaskett fires, have been burning in Monterey County, impacting more than 55,000 acres collectively.
