A grass fire in Crocker Amazon Park prompted a shelter-in-place order for John McLaren School in Visitacion Valley this afternoon, with officials telling teachers and students at the public elementary school to stay inside and close the windows. The flames covered 23 acres before the San Francisco Fire Department announced at 3:12 they had controlled the blaze.

The San Francisco Fire Department first reported the grass fire across two or three acres of the park at 1:25 p.m., saying then that the flames did not endanger any structures and there had been no injuries, it issued the shelter-in-place order at 1:38.

At 1:47, SFFD declared the "wild-land fire" a two-alarm blaze. They clarified 20 minutes later that no evacuation orders had been issued but advised people to avoid the area.

Hoodline reported that smoke from the conflagration was visible from as far away as Brisbane. A Twitter user in Daly City called the situation "insanity," saying that the entire park was "scorched black and on fire."

A second order to "continue sheltering in place" went out at 2:35 p.m.

And this is just the second fire to strike the Bay Area this warm Friday, the first being that massive construction blaze this morning in Oakland.

Stay tuned for updates.
