Dry, gusty winds could elevate the Sacramento Valley’s fire potential on Saturday morning.
A red flag warning remains in effect until 11 a.m. from Shasta County to Colusa County and the surrounding foothills, the National Weather Service said. Winds will blow from north to south at 10 to 20 mph, with gusts up to 35 mph.
The weather service said the affected areas include where the McFarland Fire is burning in the southwest tip of Shasta County and portions of Trinity and Tehama counties.
Containment on the massive Dixie Fire is at 47%, while the Caldor Fire moving closer to South Lake Tahoe is 19% contained.
California’s fires have burned almost 1.7 million acres this year.

3:30 p.m.: Dixie Fire grows with flareup west of Quincy
The Dixie Fire continues its march through parts of Northern California with the blaze growing nearly 4,000 acres from Friday night into Saturday morning.
The fire was 756,768 acres and the containment rose slightly from 47% to 48%.
“Humidity recovery was poor … allowing the fire to continue to burn actively throughout the night,” fire officials said, adding there was isolated torching of trees as the flames made short runs and embers started some spot fires ahead of the main fire.
Meanwhile, the Grizzly/Walker spot fire roared back to life Saturday afternoon west of Quincy, moving south while it sends up a sizable and very visible column of smoke, officials said.
The Grizzly and Walker spot fires have burned together south of Genesee Valley Road and the smoke plume is coming from the Wards Creek area where large timber is on fire.
Stronger winds were in the forecast for Saturday before they’re expected to strengthen Sunday and Monday.
The fire’s other most active area, its north edge, is less than 2 miles south of Highway 44 along the Shasta-Lassen county line, according to fire maps. Spot fires flared a little more than a mile south of the Hat Creek Rim.
Flames also have crept a bit farther into the northeastern quarter of Lassen Volcanic National Park.
4 a.m.: Spot fires challenge Dixie Fire lines
Dense smoke coated the sky over the Dixie Firefor most of Friday, making it difficult for motorists to see and halting firefighters’ efforts to battle the fire from the air. It also helped calm the blaze, according to Cal Fire.
Firefighters battled spots that flared up around Taylorsville, Grizzly Mountain and the Genesee Valley.
