Smoke advisory remains in effect Monday due to Woolsey Fire

(FOX 11/CNS) - A smoke advisory remained in effect Monday due to the Woolsey Fire, which was causing unhealthy air quality affecting everyone in areas directly impacted by smoke, including coastal Los Angeles County, the San Fernando Valley, the Santa Clarita Valley, the San Gabriel Valley, the San Gabriel Mountains and the Pomona-Walnut Valley.

The smell of smoke and a brown sky spread across many areas of the Southland as the fire in Los Angeles and Ventura counties grew to more than 91,500 acres with 20 percent containment.

Smoke was expected to remain at unhealthy levels closest to the fire, in the western San Fernando Valley and northwest coastal Los Angeles County.

Officials said everyone in areas where there is visible smoke or the smell of smoke were advised to avoid unnecessary outdoor exposure and to limit physical exertion, whether indoor or outdoor, such as exercise.

Children and people who have air quality-sensitive conditions, such as heart disease, asthma and other chronic respiratory diseases, should follow the recommendations and stay indoors as much as possible, even in areas where smoke, soot or ash cannot be seen or there is no smell of smoke, according to officials.
