LOS ANGELES (AP) - In Southern California, temperatures are expected to be sweltering this week, and whipping winds and dry conditions are creating a high fire danger.

Mother's Day was windy and in the mid-80s, but by midweek, temperatures could reach near triple digits in areas already badly parched by drought.

Powerful winds already have left their mark. Gusts in coastal mountains near Los Angeles reached as high as 73 mph Sunday, toppling some trees and causing power outages.

Flights taking off and landing at Los Angeles International Airport were delayed for up to an hour because of winds gusting up to 32 mph.

There also were high winds in Arizona, Nevada and New Mexico.

There are "red flag" warnings in the Los Angeles and Las Vegas areas, where authorities say any wildland flames could spread out of control.
