Add water to the utilities that may be affected by the Woolsey Fire, which has burned 91,572 acres in Ventura and Los Angeles counties.

Anyone living within the burn area is encouraged to boil their tap water for one minute before usage or use bottled water due to possible contaminates that may have entered the area's supply, according to a warning issued by Los Angeles County.

Los Angeles County Waterworks District No. 29 has issued advisories to the communities of Point Dume and Encinal Canyon. Also affected is the Las Virgenes Municipal Water District's service area bordered by Westlake Village to the north, the Ventura County Line to the west, Corral Canyon to the east and Malibu to the south.

LIVE UPDATES:

Winds have been pushing flames and helping the spread of the Woolsey Fire in Ventura and Los Angeles counties since Wednesday afternoon. As of Monday, firefighters contained 20 percent of its perimeter with full containment expected Saturday.

Two fatalities have been confirmed and 370 structures have been destroyed with thousands more threatened.

The water advisory is on top of warnings that electricity may be shut off to Southern California Edison customers across Southern California.

Due to gusty winds throughout the region, the utility company announced customers may have their power shut off to reduce the threat of wildfires.

RELATED:

Edison's announcement applies to about 50 communities, including San Bernardino, Rancho Cucamonga, San Fernando, Idyllwild and Cabazon.

Meanwhile, an air quality advisory also has been issued for communities across Southern California.

The advisory lasts through noon Monday, although Santa Ana winds could help move smoky air out of Riverside, San Bernardino and Orange counties in the coming days, according to the South Coast Air Quality Management District.

Officials, however, have warned those same winds could continue to drive fire activity.
