An Excessive Heat Warning remains in effect for the interior of the Grand Canyon where temperatures are expected to reach up to 115 degrees. Affected areas include Phantom Ranch and Supai.
The warning also includes elevations below 5,000 feet for the Page area including Lake Powell, Glen Canyon and Marble Canyon, as well as the Kingman and Lake Havasu City areas.
