Heat wave brings triple-digit temperatures to Southern California

A dangerous heat wave hit Southern California on Friday and will last until at least Thursday. Temperatures are running 15 to 20 degrees above normal across the region. The hottest day is expected to be Saturday, when some inland areas could reach 112 degrees. Los Angeles should see temperatures around 102 to 105 degrees. The heat is caused by a high-pressure system sitting over the Pacific coast. Health officials have issued an extreme heat warning for coastal and valley areas of Los Angeles County. The heat also raises the risk of wildfires, which is expected to continue into next week. Cooler weather should arrive the following Saturday, when temperatures will drop to the mid-80s.
