OKLAHOMA CITY (AP) -- Grass fires raged across Oklahoma on Wednesday, injuring two firefighters, destroying homes and forcing evacuations of schools and businesses, authorities said.

The largest fires burned in Stephens County in southwestern Oklahoma, where two volunteer firefighters suffered severe burns battling a blaze that was at least eight miles long. Their conditions were not immediately available.

At least six homes burned Wednesday evening near Meridian, where the blaze destroyed several structures and forced the evacuation of a nursing home, Darst said.

About 1,000 people had to leave the Halliburton Technical Center and the Family Dollar Distribution Center, he said, and at least 10,000 were without power in Duncan because the fires affected electricity transfer centers in the southern part of the city.

Four other fires burned in the Oklahoma City metropolitan area and blazes were reported near Chandler, Wagoner and Sallisaw in eastern Oklahoma, said Anna Payne, a state fire information officer.

"It's been a very active day today," Payne said. "We're asking people to remember there's a burn ban still in effect for Oklahoma, and tomorrow is expected to be about the same."

Lingering drought, winds of 20 to 25 mph with higher gusts and record-shattering warmth created favorable conditions for wildfires. Daytime highs reached the 80s and 90s, more than 20 degrees above average for March 1.

A fire burned Wednesday on parched grassland in northeast New Mexico, forcing a day-long evacuation of about 100 people in a small farming and ranching community. They were allowed back in the evening.

The fire, sparked by a downed power line, burned about 12,000 acres, but firefighters kept the fire from spreading into the community of Miami, said Dan Ware, state Forestry Division spokesman.
