Firefighters continue to make progress in containing the massive Hughes Fire that broke out Wednesday near Castaic Lake, growing to more than 10,000 acres and forcing mass evacuations. Around 38,000 people remain under evacuation warnings even as containment has reached 36%.

The blaze temporarily closed parts of Interstate 5 and prompted evacuation orders and warnings for more than 50,000 people.

Firefighters made progress on the more than 10,000-acre Hughes Fire Thursday, which sent thousands fleeing after sparking near the Los Angeles County community of Castaic a day earlier.

Hughes Fire initially started 10:53 a.m. Jan. 22 in Los Angeles County. It has burned 10,396 acres after being active for 33 hours. By Thursday evening, the fire crew succeeded in containing 36% of the wildfire. The cause is, however, still being investigated.
