Wall of smoke from Windy Fire blows into Los Angeles region

Smoke from Southern California's Windy Fire moved into the greater Los Angeles area.

LOS ANGELES -- Blue skies over Southern California were suddenly turning brown Thursday morning as a wall of smoke swept into the region from wildfires burning in the Sequoia National Forest.

Residents in the Los Angeles area watched as a line of smoke seemingly cut the sky in half, blotting out the sun as it marched across the sky.

One of the larger fires currently burning, named "The Windy Fire," has been burning for two weeks after being triggered by lightning.  Fire officials estimate the fire had burned just over 36,000 acres as of Wednesday evening and was just 6% contained.

Officials said three other fires are burning in the Sequoia National Park and Forest, including the similarly-sized KNP Complex Fire, which lightning started too. It had burned just over 33,000 acres as of Thursday morning. 

The smoke was recently bottled up in the southeastern California mountains, but a surge of northerly winds sweeping across Southern California Thursday has picked up some of the smoke and pushed it south toward the greater Los Angeles area, with some smoke expected to even reach the northern edges of San Diego.

Forecasts show the smoke hanging around aloft around Los Angeles through Friday, at least.
