The Arizona Department of Environmental Quality (ADEQ) has issued an Ozone Health Watch for today and tomorrow, June 17, for areas within and bordering Maricopa County.

ADEQ issues an advisory when the highest concentration of ozone or particulate matter levels may exceed the federal health standard. 

People with respiratory or other health problems that make them more sensitive to air pollution are advised to limit their outdoor activity.

Take action:

Apache-Sitgreaves National Forests (NFs) fire managers on the Black Mesa Ranger District plan to burn piles today and tomorrow, Jan. 7 and 8.

The planned prescribed burns are in the area near Hilltop Circle K, and west of Heber-Overgaard (and north of Upper Sharp – T12N, R16E, Sec. 29 and 32). Black Mesa Ranger District fire crews will burn piles which require more moisture. 

Apache-Sitgreaves National Forests (NFs) fire managers on the Lakeside Ranger and Springerville ranger districts plan to conduct pile burns today, weather conditions permitting.

The planned prescribed burns are in the Morgan Wash area, west of Porter Mountain Estates off Forest Road 45; and the area of Water Canyon Pit, Greer Pit and Greens Peak Hideaway Pit, where crews will burn approximately 100 acres near the southwest end of Forest Road 87.  

Fire managers on the Prescott National Forest are planning to continue treatment on several projects across the forest beginning Tuesday, November 4 through Tuesday, November 11; pending favorable weather conditions.  Specific days to burn will be determined by current and expected weather patterns allowing fire managers to make every effort to achieve objectives of the burn and minimize overall smoke production . 

The Arizona Department of Environmental Quality (ADEQ) has issued a same day PM-10 Health Watch.

There is an area of low-pressure tracking across the southern Arizona border. Enough atmospheric instability and moisture should be present to generate afternoon shower and thunderstorm activity for the eastern half of the state. This would include the dust prone areas,

Fire managers anticipate starting multiple prescribed fire treatment projects on the Tusayan Ranger District as early as Thursday. Officials hope to treat approximately 3,000 acres with fire before wet weather conditions arrive for the winter.

Prescribed fire treatments require that fire managers continuously monitor weather and fuel conditions throughout the treatment process in order to ensure firefighter and visitor safety. The following prescribed treatments are scheduled for the upcoming week but will only be implemented only once conditions are favorable to do so:
