Nucla, Colo. (AP) - Crews fighting a 1-square-mile wildfire in Western Colorado are also putting out 17 smaller fires sparked by lightning.
Fire Information Officer Lee Ann Loupe says a Sunday night storm sparked the new fires while crews were keeping the large fire away from three cabins and an outbuilding about 10 miles north of Nucla.
Firefighters are bracing for extreme fire behavior Monday afternoon.
The National Weather Service issued a ``red flag'' warning indicating high fire danger in Western Colorado Monday, with gusts and low humidity making conditions ripe for rapid fire growth.
The larger fire was reported Saturday and is believed to be caused by lightning. Firefighters had no estimate Monday on how much of the fire was contained.
