Firefighters are making progress on the Sheep Fire 24 miles northwest of Idaho Falls, Idaho. The fire is on land administered by the Idaho National Laboratory (INL), an agency within the Department of Energy. (scroll down to see a map)
At a briefing Wednesday the fire chief said containment has increased to the point where they expect to release 5 of the 17 engine crews later in the day. He said no “buildings” have burned but some “power structures” were damaged. A backfiring operation was executed on the south side of the fire Wednesday night. About 105 personnel are assigned to the fire.
Wednesday the size of the fire was estimated at 110,000 acres, an increase of 20,000 acres from Tuesday.
Firefighters were challenged Wednesday by strong winds. A weather station in Idaho Falls recorded sustained winds at 20 to 25 mph with gusts above 35 along with a high of 90 degrees and relative humidity in the teens. The forecast for Thursday at the fire area is about the same, except with much diminished winds — 12 mph with gusts to 21 in the afternoon.
Officials at the INL said Wednesday that there has been no release of radiation due to the fire.
Most of the workers at the INL were evacuated from the lab facilities, but there appears to be a good chance they will be allowed to return to work on Thursday.
Photos and videos of the fire, including videos of air tanker drops filmed from overhead by Air Attack, can be found here.

UPDATE: Work continues to be curtailed for non-essential employees at some facilities at the INL Site Wednesday as firefighters continue to contain the #SheepFire. It is anticipated that operations across the Site will return to normal on Thursday. More: https://t.co/crK3BkrPyB

The Sheep Fire on property managed by the Idaho National Laboratory (INL) has burned approximately 90,000 acres in the first 24 hours. The facility about 24 miles northwest of Idaho Falls conducts nuclear research. (see the map below)
All non-essential employees were evacuated from several facilities at the lab: Central Facilities Area, Advanced Test Reactor Complex, Naval Reactors Facility, Radioactive Waste Management Complex, and Idaho Nuclear Technology and Engineering Center.
INL Site facilities are preparing for the anticipated loss of commercial power and are switching to on-site backups per existing emergency procedures.
Radiation monitoring is ongoing, and based on current information there is no risk to the public, according to information released by the INL.
The Sheep Fire started at about 6:30 p.m. Monday from a lightning strike, and later that night other fires were started by lightning in the area. It is being managed by the Bureau of Land Management and is burning between Highways 20 and 33.
The weather forecast for the fire area until dark on Tuesday predicts 16 mph winds gusting to 24 out of the southwest, 25 percent relative humidity, and temperatures around 90. Wednesday should bring winds out of the southwest at 24 mph gusting to 35, 88 degrees, and relative humidity of 18 percent.
Another fire in Idaho, the Lava Fire, has burned 800 acres north of Shoshone. (see the map above)
