The map above was updated using data from a fixed wing mapping flight over the Loyalton Fire Sunday afternoon at 4:30. It is more accurate than the map below from an earlier flight that was supplemented with the red dots representing heat detected by a satellite. That flight plus data collected later by other means determined the fire had burned 36,295 acres

The Loyalton Fire in northeast California 12 miles northwest of Reno, Nevada started at about 4:30 p.m. August 14 east of Loyalton, California. It burned north and east adjacent to the areas of Beckwourth Pass and Hallelujah Junction. Early Sunday morning a mapping flight calculated it had burned 29,829 acres. That was confirmed later in the day by the Tahoe National Forest.
Sunday afternoon it was pushed to the east and southeast by an 8 to 15 mph wind out of the northwest and was approaching the Nevada border at 2:48 P.M. MDT.
On August 15 meteorologists with the National Weather Service in Reno observed on radar a very rare fire tornado in real time at the Loyalton Fire about 12 miles northwest of the city. They used emergency warning systems to transmit tornado warnings as quickly as possible to firefighters and the general public. It is believed that this is the first time a real time warning for a fire tornado has ever happened, at least in the United States. More information about this very unusual event is at Wildfire Today.
Sunday at 5 p.m. the Lassen County Sheriff’s office issued the following evacuation information:
