Lightning-Sparked Idaho Fire Burns More Than 90,000 Acres

A fire that sparked in Elmore County, Idaho, has grown exponentially since Thursday evening.

Also known as the Elk Fire, the initial flare, which started from a lightning storm, swelled to 90,249 acres in just a matter of days.

Most of this fire is in an extremely rural area and is not currently threatening any homes or structures; however, smoke has been spreading far and wide.

Winds Monday allowed smoke to drift all the way to Boise and Hailey, making for hazy conditions across the area.

The visibility has been poor in the area for days, and was so hampered on Saturday when Idaho law enforcement were scouring central Idaho for missing teen Hannah Anderson, who was reportedly held captive and taken into the Idaho wilderness.

Unfortunately, as of 8:00 a.m. PDT on Monday, the fire was only 5 percent contained.

Due to vast area the fire covers, as well as the tricky terrain, firefighters don't expect the blaze to be fully contained until the start of October.

Multiple road closures are expected to continue, including roads off of I-84, where Stage 1 fire restrictions remain in place.

Spotty storms could also erupt Monday evening, especially in the higher terrain. Not only does this risk bring even further danger to firefighters battling the blaze, but lightning could spark even more fires in the area.

Otherwise, dry and hot conditions are expected to persist throughout the week, bringing little help to the containment effort.
