The massive wildfire near California's Yosemite National Park forced thousands more people to evacuate on Monday and had burned across more than 17,200 acres at 16% containment in the evening, per Cal Fire.

The big picture: The Oak Fire in Mariposa County, where a state of emergency has been declared, is now California's biggest blaze this wildfire season despite only igniting on Friday amid face hot, dry conditions.

Yes, but: The Oak Fire showed signs of slowing after more than doubling in size over the weekend.

Threat level: The wildfire has razed 55 structures and forced the closure of a highway near Yosemite, which is still recovering from the Washburn Fire that threatened the world's oldest giant sequoia trees earlier this month.

By the numbers: Nearly 3,000 firefighting personnel have been deployed to tackle the wildfire, along with 24 helicopters, 68 water tenders and other firefighting resources, according to Cal Fire.

Our thought bubble, via Axios' Andrew Freedman: While the fire's rapid growth rate is impressive, it pales in comparison to the megafires we've seen in recent years.

The bottom line: It doesn't bode well for the state, given the fire season in parts of California continues into October or November.
