Wildfires burning at or near the Grand Canyon's North Rim are still raging as strong winds, high heat and low humidity persist.

A new emergency system for the Grand Canyon is getting life-saving messages to people with little cellphone service.

The NWS warning was in effect for regions of the Grand Canyon below 4,000 feet elevation. Temperatures were forecast to potentially reach 110 degrees at Phantom Ranch and 102 at Havasupai Gardens.

The Grand Canyon National Park’s North Rim, often described as the park’s quieter, wilder side, is now closed indefinitely following a fast-moving wildfire that has engulfed more than 8,500 acres and destroyed dozens of structures, including one of the park’s most beloved landmarks, the historic Grand Canyon Lodge.
