A wildfire burning near the Grand Canyon has grown into what experts call a 'megafire,' and it has even developed its own weather.

The Grand Canyon has been on fire for a month, as crews continue to battle the continental United States' largest wildfire this year.

According to the fire tracking app WatchDuty, as of Monday, the fire had burned through over 120,000 acres. However, the blaze is only 16% contained, as dry vegetation and low humidity have made fighting it increasingly difficult.
