The Latest on California wildfires (all times local):

6 a.m.

Southern California firefighters face another day of difficult weather conditions as they battle a huge wildfire that has driven more than 80,000 people from their homes and shut down major transportation routes.

The National Weather Service says conditions will be very warm and dry Wednesday, with gusty south to southwest winds and very low humidity levels — as low as 3 percent in the afternoon.

The fire broke out late Tuesday morning 60 miles east of Los Angeles in Cajon Pass and spread with astonishing speed over 28 square miles, burning an unknown number of homes and threatening many more.
