WESTERN HEAT DOME: DEALING WITH THE EXTREME HEAT

ALEX STONE, ABC NEWS CORRESPONDENT, LOS ANGELES @astoneabcnews

The Western U.S. is in the grips of an extended heat wave with temperatures today in many areas in the 110 degree range.  It will get even hotter through Sunday before slowly dropping again.  But temperatures are expected to stay above 100 degrees in many areas through next Wednesday.  Governor Gavin Newsom is addressing the state today on the response to what could end up being a heat emergency.  The state is warning energy conservation measures will probably be ordered to prevent blackouts.  Flex Alerts, as they are called, would call on Californians to turn up their thermostats and to not run appliances from 4 to 9pm to reduce demand on the electrical grid.  Cooling enters are opening and schools are getting creative to help students -- especially in older schools that don’t have air conditioning.
