According to the U.S. Forest Service, the fire has grown to more than 1,500 acres and is currently being battled by 259 people. About 5 percent of the fire’s perimeter has been contained.

“Currently, smoke impacts are concentrated in the mountainous and foothill areas of the air basin, but impacts on the Valley floor are possible until the fire is extinguished,” according to an Air District news release.

People with existing respiratory conditions, young children and the elderly are especially vulnerable to health effects from the particulate matter.

The district advises resident to follow their doctor’s orders when exposed to wildfire emissions and stay indoors if possible.
