A fire broke out early this (Thursday) morning. The wildfire started just after 1am this morning near Arrow Rock and has already grown to over 150 acres.

The Bureau of Land Management and the Forrest Service are currently battling the flames which they've named the Lucky Fire, which tripled in size in only an hour.

Wind and terrain are making the Lucky Fire difficult to battle. While no homes are threatened by the flames currently, the fire is zero percent contained as of now.
