LOS ANGELES (AP) – Authorities say California is facing its highest chance of blackouts this week as a brutal heat wave continues to blanket the state with triple-digit heat.Officials are pleading for more conservation as people crank up their air conditioners. The state says energy use could hit its highest-ever levels Tuesday afternoon. The National Weather Service is predicting highs of as much as 115 degrees. It’s particularly tough on firefighters, battling 14 large fires around the state. In Southern California alone, two people were killed and one was injured by the Fairview Fire, which has burned more than 2,000 acres near the city of Hemet.
