FORT COLLINS, Colo. (AP) — A 40-acre wildfire burning in gusty winds and warm weather in northern Colorado was threatening homes west of Fort Collins and has caused about 50 people to leave the area.

The fire started burning near the visitors’ center in Lory State Park in an area near where a large wildfire burned 259 homes last summer. Firefighters were also battling another smaller fire nearby.

Crews appear to have made some progress stopping the fire’s advance toward homes to the north and were focusing on the fire’s southern end.

Poudre Fire Capt. Patrick Love said aircraft have been requested to fight the fire but he doesn’t believe any are in the area so early in the year.

Temperatures are in the 70s along Colorado’s Front Range but part of a reservoir near the fire is still frozen.
