A long-lasting, severe heat wave is building up across the West Coast, according to federal weather forecasters on Friday.
Temperatures are expected to reach well above 100 degrees Fahrenheit for many locations on Friday and Saturday. In some places, the temperatures could reach 110 degrees F or greater, and in the desert southwest region, highs of 120 degrees may be possible, say federal forecasters with the National Weather Service in its most recent bulletin.
