(Posted on June 11, 2012 at 8:30 p.m.) The 257 Fire is approximately 2,400 acres and zero percent contained.
The Arizona Central West Zone Incident Management Team, Bea Day Incident Commander, assumed responsibility for suppression of the 257 Fire at 7:00 p.m. today. Additional resources have been ordered and are responding to the incident.
Driven by wind, rugged terrain and dry fuels, the 257 Fire was active today, pushing east northeast. Low relative humidity and dry fuels contributed to active fire behavior. Drought conditions in Arizona continue with precipitation this year at approximately 40% of normal.
Firefighters worked to anchor the fire on the west side and used air support to minimize fire effects to an APS power line east of the fire. As a result of work completed along the western boundary, Highway 177 was reopened at 7 pm Monday evening.
Threats: The power line east of the fire is a concern but remains energized at this time. No structures are threatened. Numerous mining shafts and adits occur in the area and active exploratory drilling operations occur north of the fire. These operations have been temporarily suspended. There are no evacuations at this time.
Smoke: Smoke from the 257 Fire is drifting to the east northeast during the day. Overnight, smoke will likely descend and follows drainages west into the community of Superior. ADEQ has installed an air quality monitor in Superior to record smoke levels. Smoke is pushing through the Globe/ Miami area however levels are currently below those which might cause health concerns. For smoke information, air quality forecasts, and to view information from the monitor, please visit the Arizona Department of Environmental Quality website at www.azdeq.gov/environ/air/smoke/fire.html.
Visibility is an excellent measure of air quality. If visibility is ten miles or more, the air quality is good. Visibility of six to nine miles indicates moderate air quality. Three to five miles of visibility indicates conditions unhealthy for sensitive groups. One and a half to two and a half miles, the air quality is unhealthy. One to one and a quarter miles indicates the air quality is very unhealthy. If visibility due to smoke is less than a mile, the air quality is hazardous. Smoke sensitive persons in affected areas may need to take action to mitigate the conditions. Remaining indoors, using air conditioning or temporarily moving to an unaffected area may be necessary.
