Fires tearing through the Los Angeles area have killed at least 24 people, displaced thousands of others and destroyed more than 12,000 structures. The blazes started last Tuesday, fueled by fierce Santa Ana winds that forecasters expect to kick back up through at least midweek. Cal Fire reported that the Palisades, Eaton, Kenneth and Hurst fires have consumed about 62 square miles. The Palisades Fire, along the coast, has been blamed for eight deaths, while the Eaton Fire further inland has been blamed for 16 others, the LA County medical examiner’s office said. At least 23 people are missing, and authorities said that number is expected to rise. Investigators are still trying to determine what sparked the fires. They could be the nation’s costliest ever. Government agencies haven’t provided preliminary damage estimates yet, but AccuWeather, a company that provides data on weather and its impact, puts the damage and economic losses at $250 billion to $275 billion.
