The Sacramento Bee is reporting that 100 homes have been destroyed in the Mill Fire, according to the Mayor and a CAL FIRE Unit Chief. Most of the homes were in the Lincoln Height area.

The nearby Mountain Fire is smoked in, making it impossible for firefighting aircraft to work.

However, there is a NOAA Twin Otter aircraft flying an interesting square pattern over the fire at 14,500 feet. It may be collecting smoke or air quality data.

The 3,921-acre Mill Fire has destroyed multiple structures in the town of Weed, 56 air miles north of Redding California. Videos posted online showed residential areas burning as well as one industrial building. Thermal imagery recorded by the FIRIS mapping aircraft showed intense heat at the site of dozens of structures.

The spread of the Mill Fire slowed overnight as the winds that were gusting at more than 20 mph hour Friday afternoon decreased to 4 mph after midnight and the relative humidity rose to 54 percent.

The Mayor of Weed told the LA Times that the fire appeared to have started at a lumber mill near the town.

Suzi Brady, a CAL FIRE spokeswoman, said several people were injured. At least two were treated at hospitals, NPR reported.

Another fire in the area, the Mountain Fire, was very active through the night. It has spread about five miles north since it started near Gazelle Callahan Road 12 air miles west of Weed. It is about 6 miles southwest of Gazelle. CAL FIRE reports it has burned 1,464 acres, but current unofficial estimates put it more than double that figure.

Both fires are burning primarily on private land, but the Mountain Fire started near the boundary of the Shasta-Trinity National Forest and burned some of the Forest east of Gazelle Callahan Road.

The Mill Fire has light fuel loadings out ahead, and to the east is the burn scar of last year’s 26,000-acre Lava Fire.

The Mountain Fire on the other hand is surrounded by private timber land with no significant recorded history of fire in the National Interagency Fire Center database. However that database is often lacking complete information. It has the potential for growth in all directions, including through numerous clear cuts with dry, light to medium flashy fuel.

At about 8:10 p.m. the FIRIS aircraft mapped the Mill Fire at 3,921 acres, showing that it had burned from Weed, California north to the shore of Lake Shastina, a distance of nearly six miles.

The Mountain Fire 12 air miles west of Weed near Gazelle Callahan Road has burned approximately 700 acres. It is about 9 miles southwest of Gazelle.

Weather

Friday afternoon a weather station just southeast of Weed recorded 89 degrees, 7 percent relative humidity, and 12 mph winds gusting at 20 to 26 mph out of the east-southeast.

Friday night the winds should decrease to 5 to 10 mph out of the south after sunset, then decrease to 2 to 4 mph after midnight with a maximum RH of 45 percent.

The spot weather forecast for Saturday predicts 88 degrees, 12 percent RH, and winds out of the north at 1 to 3 mph.

The slower wind speeds should give firefighters a chance to put in some direct fireline on Saturday.

  1. There is nothing like getting a Mill wood processing plant on fire to give a new start a big advantage. I wonder if there will be after dark helicopter drops. CalFire has done a good job of adding additional type I helicopters throughout the State. Many new fire starts have been quickly contained with the assistance of these resources.
    Team work air and ground. Maybe next year the return of a State contracted tanker of over 15,000 U.S. gallons that can deliver a half mile of retardant at coverage level plus six.
