PORTLAND, Ore. (AP) — Smoke and heat from a massive wildfire in southeastern Oregon are creating giant “fire clouds” over the blaze — dangerous columns of smoke and ash that can reach up to 6 miles (10 kilometers) in the sky and are visible from more than 100 miles (160 kilometers) away.
Authorities have put these clouds at the top of the list of the extreme fire behavior they are seeing on the Bootleg Fire, the largest wildfire burning in the U.S. The inferno grew Friday to about 75 square miles (194 square kilometers) larger than the size of New York City and was raging through a part of the U.S. West that is enduring a historic drought.
The fire was so dangerous late Thursday and into Friday that authorities pulled out crews. Meteorologists this week also spotted a bigger, more extreme form of fire clouds — ones that can create their own weather, including “fire tornadoes.”
