Police in Glendora, California have arrested three men, one of them homeless, for allegedly starting a massive wildfire that continues to burn near Los Angeles.

Gov. Jerry Brown (D) has declared a drought emergency. The dry conditions combined with the Santa Ana winds are fueling the fire, with several homes destroyed and thousands of residents forced to evacuate.

William La Jeunesse reported this morning from near the bone-dry San Gabriel River outside of Los Angeles. He said, so far, the blaze has not breached containment lines, and fire crews have been able to protect homes for the most part.

Authorities say one of the men expressed remorse for causing the blaze, saying the group was camping and had started a fire to keep warm. It quickly got out of control and they fled down the mountain.
