Wildfires burn nearly 2,000 acres in Colorado

MONTROSE, Colorado (CNN) -- Firefighters were focusing Wednesday on two wildfires caused by lightning that have burned nearly 2,000 acres in the Uncompahgre National Forest in southwest Colorado.

No injuries have been reported, and only a few cabins have been threatened by the flames, said Dale Erickson with the Rocky Mountain Incident Management Team, a regional group of federal, state and local firefighters.

About 450 federal firefighters were to join five 20-person crews on the fire lines Wednesday.

The fires, along with two others that were contained Tuesday, are believed to have begun Sunday. There were 640 lightning strikes reported in the area between 9 a.m. Sunday and 8 a.m. Monday, Erickson said.

The largest blaze was the Bucktail fire, burning on 1,700 acres about eight miles northeast of Nucla. The 47 fire, named after a historic cow camp, covered more than 250 acres 12 miles northeast of Nucla, near the Bucktail blaze, Erickson said.

Firefighters were prevented from fighting the two fires Tuesday because of wind gusts up to 50 mph. Wednesday's weather was calmer.

"The action plan for today is to monitor the 47 fire and do a direct attack on the Bucktail fire," Erickson said.

The two fires controlled Tuesday were north of Norwood, and burned only about a dozen acres before being contained.
