Update On The South Fork Fire Thursday 7 AM

YOSEMITE — The evacuation order for residents of the community of Wawona was lifted yesterday morning, and today at 7 a.m., the public was allowed to return.

The fire is now estimated at 4,188 acres and is 25 percent contained.

There are currently 422 personnel assigned to the incident including 8 hand crews, 5 helicopters and 10 engines. Some crews are being demobilized to return to their home units.

Last night’s infrared flight shows significant reduction in heat in the western half of the fire. The fire is still active in the portion north of the river.

Smoke continues to be dense in the valleys in and surrounding the Yosemite area, especially in the morning hours. Oakhurst and Mariposa are experiencing smoky conditions into the afternoon.

Poor air quality continue to be an issue in the park.

Firelines around the community of Wawona have been secured. The fire remains active in the northeast, and natural barriers are being utilized as much as possible in securing the fire’s edge in that area, where there is a lot of rocky terrain.

Crews continue to hit hot spots and secure lines in the southeast portion in an effort to halt the eastern spread of the fire.

Crews will continue to do mop-up and monitor the perimeter, and aircraft will assist in securing the line as needed, and as conditions allow after the inversion lifts.

Temperatures are predicted to be near normal and the threat of storms is greatly decreased for the rest of the week.

The incident is scheduled to transition from the South Central Sierra Interagency Incident Management Team to a Type 3 organization on Friday, Aug. 25, at 6 a.m. The new team will continue to update the fire. For information about the South Fork Fire after today, call 209-379-1493 or email yose_fire_info@nps.gov.

For the rest of today, the live information phone number and email for the South Fork Fire will be answered at 209-379-5322, or email SouthForkFireinfo@gmail.com.

All roads within the park remain open to travel.

The cause of the fire is under investigation.

The estimated date of containment is Sunday, Sept. 3.
