Thousands of firefighters worked to contain three new blazes Thursday, including one near the affluent Bel-Air neighborhood, while persistent winds left weary Angelenos on edge following weeks of historic fires.

CASTAIC, Calif. (AP) — Firefighters fought to maintain the upper hand on a huge and rapidly moving wildfire that swept through rugged mountains north of Los Angeles and resulted in more than 50,000 people being put under evacuation orders or warnings.

Palisades Fire initially started 10:30 a.m. Jan. 7 in Los Angeles County. It has burned 23,448 acres after being active for 15 days. A crew of 3,274 firefighters has been working on site and they managed to contain 70% of the fire by Wednesday evening. The blaze's cause remains under investigation.

The Hughes fire about 50 miles north of Los Angeles further taxed firefighters in the region who have managed to bring two major fires in the metropolitan area largely under control.
