The Latest on California wildfires (all times local):

6:30 a.m.

A scenic stretch of California's Highway 1 is open, but state parks near Big Sur remain closed as crews try to beat back a destructive wildfire that threatens to crest a ridge and make a run toward coastal campgrounds, lodges and redwoods.

Firefighters working around the clock got a break early Wednesday from cooler temperatures and increased humidity. The blaze that has destroyed 20 homes and charred 36 square miles of brush was only 10 percent contained late Tuesday.

To the south, firefighters continue to make progress containing a huge blaze in mountains outside Los Angeles. Crews face another day of temperatures in the 90s to low 100s as they fight the fire that has destroyed 18 homes near Santa Clarita.
