Firefighters battled a wind-whipped wildfire in the inland mountains of Southern California on Friday as unseasonably hot weather heightened fire danger in a region where little rain has fallen this winter.

The Bonita Fire erupted shortly after 1 a.m. and quickly grew to 715 acres. Fire crews stopped its progress, but it remained only 20% contained.

The fire triggered evacuations in Mountain Center, a tiny community in the San Jacinto Mountains about 90 miles east of Los Angeles.

The blaze burned in heavy vegetation, including pine trees, Cal Fire/Riverside County said in a statement.

Temperatures in the region have reached summer-like highs in the 80s and low 90s, and Santa Ana winds bringing in extremely dry air are contributing to the threat of disastrous wildlifres..
