A fire burning about 25 miles west and south of Mount Shasta tripled in size rapidly Friday afternoon because of low relative humidity and high temperature, according to the Shasta-Trinity National Forest.

The smoke that rose rapidly above the Eddys west of Mount Shasta Friday afternoon, Aug. 1, and began spreading north is reported to be coming from one of two wildfires burning in the Trinity Alps Wilderness.

A news release from the Shasta-Trinity National Forest says “low relative humidity and increased afternoon temperatures have adversely impacted fire behavior causing the Coffee Creek fire to triple in size very rapidly.”

More than 105 federal firefighters were engaged in suppression efforts as of Friday afternoon, dealing with rugged terrain accessible only by foot, according to the release.

The fire was started by lightning Wednesday evening, July 30, on the east fork of the Coffee Creek Drainage, about 25 miles west and south of Mount Shasta.

More lightning is predicted for the next few days into next week.

Twenty-eight personnel were engaged in fire suppression activities as of Friday afternoon on the Rays fire, located near Rays Peak in the Trinity Alps Wilderness, according to the Forest Service.

That fire is burning in a previous fire scar in brush, downed timber and snags, and is spreading at a moderate rate, according to the release.

It had grown to about 15 acres.
