The White Sage Fire near the Grand Canyon's North Rim has exploded to nearly 11,000 acres in 24 hours, forcing evacuations of 500 visitors. Ignited by lightning, the 0% contained blaze, along with the Dragon Bravo Fire (1,500 acres), prompted closures of Grand Canyon and Black Canyon National Parks. High temperatures, low humidity, and strong winds fueled the rapid spread, impacting air quality and making hiking inadvisable.
