Firefighters swarmed to a blaze on Airport Road Thursday morning about one mile east of New Mexico 48 as sheriff's deputies went door to door advising nearby residents to leave the area. Strong and shifting winds made it hard for fire crews to decide how to contain the blaze or predict which way it might move. Law enforcement blocked off Airport Road at its intersection with Highway 48, and the county activated its Code Red reverse 911 system to homes that appeared to be directly threatened.
