The fire has crossed to the east of Old Highway 99 this afternoon. Firefighters are working aggressively to keep the fire from spotting to the east of I 5.

The hot dry weather, combined with extremely dry fuels continues to create extreme fire behavior. Burnout operations supported by aircraft are being used in an effort to slow the fire as it moves toward I 5. Crews and engines are positioned along I 5 and are prepared to take immediate action if the fires spots across the freeway.

• Currently there are no evacuations in place.

• Interstate 5 will reopen when safe conditions are assured.

• Firelines on the north end of the fire near White Mountain are holding well.

Dense smoke from the fire is affecting a wide area including the Interstate 5 corridor. Motorists should use caution when traveling through this area. The potential exists for the wind to change and come out of the northeast. If this occurs smoke could impact the communities of Fillmore and Piru.

Forest Service investigators have determined that the Day Fire is human-caused, and that it resulted from a member of the public burning a small amount of material within the Los Padres National Forest. The investigation into the cause of the fire is continuing and potential suspects and witnesses are being interviewed.

Out of concern for public and firefighter safety, an emergency fire closure has been imposed in the general area of the Day Fire. The closures include:

• The eastern half of Sespe Wilderness and adjacent lands in Los Padres National Forest and Angeles National Forest lands west of Interstate 5 and south of Hardluck Road

• Pyramind Lake Recreation Area and Oak Flat area

• Hungry Valley State Vehicular Recreation Area

• Gold Hill Road

• Smokey Bear Road at Interstate 5.
