NEZ PERCE COUNTY, Idaho -

Firefighters have made progress suppressing Idaho's largest wildfire but anticipated extreme fire weather conditions could make putting it out the difficult in the next few days.

The lightning-caused Big Cougar fire is burning on the Idaho side of the Snake River near the Oregon and Washington border and has burned more than 101 square miles.

Firefighters have contained nearly half of the flames since the fire first erupted Aug. 2.

Fire officials say triple-digit temperatures are expected to challenge firefighters Monday and high wind gusts will drop into the fire region later this week.

Overall, wildfires are burning currently nearly 123 square miles throughout Idaho.
