Northern California wildfire threatens homes, closes major highway

The Delta fire erupted on Wednesday in a canyon along the Sacramento River about 250 miles north of San Francisco and by Thursday morning had scorched more than 15,000 acres, triple the area that had burned some 12 hours earlier. The blaze was near where the deadly Carr fire incinerated hundreds of dwellings in and around the town of Redding this summer. No casualties have been reported from the Delta fire but there were some close calls.
