Favorable weather and unstinting efforts by firefighters are helping to bring a trio of destructive wildfires in California under control, state and local officials said Saturday.

Three large wildfires are still largely uncontrolled, but an incoming cold front and cloudy weather this weekend are expected to offer some reprieve, officials said Saturday.

Crews battling three major California fires could get some relief from record heat and help from the weather as a cooldown preceded minor containment for the blazes.

The three wildfires that have ravaged the mountains east of L.A., destroying dozens of homes, injuring a dozen people and burning more than 155 square miles, still pose threats to some communities.
