How to protect your family from wildfires

A California wildfire has killed at least 17 people, and authorities have confirmed the death toll is more than 20, state officials said Wednesday.

The massive fire in Northern California, about 40 miles (64 kilometers) south of Los Angeles, started Tuesday afternoon and is burning near the town of Larkspur, officials said.

The fire, which has been burning for nearly two weeks, caused a power outage in the community of Lake Berryessa, about 25 miles (40 kilometers) southeast of Larkdale.

Officials have said no structures have been damaged, but the blaze has also destroyed some homes and damaged nearby roads.

The Cal Fire said Wednesday that there was no significant fire risk from the blaze, which is burning in a remote area.

The fire was still burning Wednesday in the hills near Lake Berryesse, the fire department said.

The department warned residents to avoid driving or using the roads, and said they should leave homes and vehicles when they are dry.

Officials are urging residents to conserve water and reduce their outdoor activity, and to follow evacuation orders, which are to include avoiding roads and other areas of concern.
