Record high temperatures, which surpassed 100 degrees this week, have exacerbated wildfires burning in the region. As of Tuesday, July 8, there were 150 fires burning in Northern California and more than 300,000 acres had been scorched, according to a joint information center for Northern California fires.
Many of the fires were contained during the cooler temperatures over the Fourth of July weekend, officials said. However the recent heat wave caused the smoldering fires to flare up and small ones to merge. Hundreds of wildfires ignited after a lightning storm swept through the state late last month, from the Oregon border south to Fresno.
