Over a dozen major fires are burning across California, killing seven people so far, destroying over 1,200 structures, spurring tens of thousands of evacuees — and reaching record-breaking proportions.

As of Monday, two major fires in Northern California — theLNU Lightning Complex fires in Napa County and the SCU Lightning Complex fires in Santa Clara County — had both blazed through over 345,000 acres, making them, respectively, the second- and third-largest fires in state history.
