Welp, I guess we have a fire day on our hands. An apartment fire broke out in a building on the 500 block of Guerrero, near 18th. According to Twitter user Jessica Kennedy, who's a neighbor to the rear, the fire appears to have already been extinguished as of just before noon.

Below is an after shot of the possibly extinguished blaze, which appears to have affected the rear of the building.

It's unclear if there were any injuries or if anyone was at home. We will update you as we learn more.
