Overnight, the Mendocino Complex Fire in Northern California expanded far enough to oust the 2017 Thomas Fire as the largest wildfire in the state’s history. Comprising two joined fires, the Mendocino Complex Fire has burned through 443 square miles in the area north of San Francisco. As of Tuesday morning, the fires burned more than 140 structures, including at least 75 homes, and was 30% contained.

But California’s residents and businesses still should be on alert, as the incendiary activity doesn’t end there. An unprecedented 14,000 firefighters are combating between 12 and 16 wildfires in the state, according to the Department of Forestry and Fire Protection. Particular emphasis is in Northern California, where the fires in Mariposa and Shasta counties continue to threaten residents, businesses, and emergency responders. For 26 days, the Ferguson Fire in Mariposa County has burned nearly 90,000 acres and caused two fatalities. The fire is having a huge impact on areas near and around Yosemite National Park, which alerted the public that it had closed all but two entrances and roads.

Redding, a city 150 miles north of Sacramento, is the site of the Carr Fire, which has been ablaze for two weeks. Weather.com reported that the fire has caused seven deaths and the destruction of nearly 1,600 structures, the majority of which are homes.

The city of Redding launched an interactive map that provides residents with images of neighborhoods so they can check the status of their homes. Reports indicate that more than 1,800 structures are still in the path of the fire.
