Arizona's wildfires continue to grow and have now spread across the border into the state of New Mexico. The Wallow Fire, which broke out in what authorities believe was an unattended campfire in the Apache-Sitgreaves National Forest on May 29, has now spread to around 450,000 acres, destroying 29 houses and damaging another 5. Some 2,700 residences remain threatened. Full evacuation of the Arizona towns of Springerville and Eager, which have 2,000 and 4,000 residents respectively, has been lifted, though fire activity and health risks associated with the air quality continue. Evacuations remain effective in Sunrise, Greer, Blue River, Alpine, Nutrioso, as well as the Escudilla Mountain Estates, Bonita, White Mountain Acres, and the H-V Ranch. While firefighters have extended their burnout operations just northwest of Luna, New Mexico, no evacuations have been ordered in the state. There are currently more than 4,000 firefighters from across the United States working in the area with 15 helicopters and 5 air tankers available to fight the fires - which are expected to cost over $10 million in damages.
