text:  The scorching temperatures are drying out vegetation and contributing to wildfires in a handful of western states, including California, where a fire burning in the mountains north of Santa Barbara has become the biggest wildfire in the state so far this year. Fire officials say the high temperatures are complicating firefighting efforts. Several air tankers and helicopters have been assigned to the blaze, as well as hundreds of wildland firefighters.
