Wildfire smoke from Canada is blanketing the skies in the Midwest, leaving millions with dangerous breathing conditions.

The smoke is expected to remain over the northern and central Plains of the United States for the next couple of days, according to meteorologists.

The Dragon Bravo Fire, which has burned since July 4 on the Grand Canyon's North Rim, has become the largest wildfire in the continental United States in 2025.

A video shared by a local fire emergency team shows thick plumes of orange-hued smoke rise into the sky creating a fire cloud.

The wildfire that destroyed the historic Grand Canyon Lodge​ earlier this month has expanded in recent days, fueled by hot, dry conditions, fire officials in Arizona said.
