The Flat Fire that began a little after 3 p.m. yesterday near Burnt Ranch in western Trinity County when a crash on State Route 299 caught the hillside on fire, as of this morning, has spread to approximately 100 acres and is zero percent contained, according to the Northern California Geographic Coordination Center.

The fire is primarily burning in grass and brush.

“Minimal fire activity was reported overnight,” the center reported. “Structures remain threatened and an evacuation warning remains in place.”

The center warns that power-lines in the area are also threatened.

Caltrans tweeted this morning: “If you’re planning on traveling Route 299 east of Burnt Ranch in Trinity County (PM 13.2), please expect delays. Helicopter operations to fight the wildfire in the area could cause two-hour delays.”

Local resident Paul Turner who provided these images from the fire yesterday described seeing “the hot spots burning all night.”
