Slow going in fight against deadly fires in California

The wind known as the Diablo is picking up again, the air is dry, there is no rain in sight and the killer wildfires that have scorched the wine country of Northern California remain almost completely uncontained. Officials warned Wednesday that some of the big fires could merge. Amid these grim bulletins, the huge utility company PG&E acknowledged that the extreme winds late Sunday and early Monday had knocked trees into power lines in conditions conducive to wildfires.
