In the Pine Cove evacuation warning, authorities described a dangerous "ice cap" that could form atop a column of smoke and ash northwest of the fire. The smoke column could create create a thunderstorm, and associated lightning and wind.
"Eventually the weight of the ice will cause the column to collapse. When the column collapses, strong downdraft winds push the fire in multiple directions, placing firefighters at risk," the warning stated....
We've been hoping the rain will clear the air and douse the fire here, but apparently it's just another careful what you wish for kind of situation.
