Summary
Monday’s watch covers 10 a.m. through 7 p.m. Tuesday in the lower Grand Canyon, where the National Weather Service said temperatures could reach 112F and create dangerous conditions below 4,000 feet.
Flagstaff forecasters warned most people face heat illness without cooling or hydration, with highs expected from 97F at Havasupai Gardens to 111F at Phantom Ranch; hikers were told to avoid the canyon from 10 a.m. to 4 p.m.
Three hikers died in two heat-related incidents on June 12 and June 16 in the Inner Canyon, where the National Park Service said midday shade temperatures can exceed 109F; an 18-year-old also died earlier this month after heat-related symptoms.
The alert comes as extreme heat watches and advisories spread across parts of Oregon, California, Texas, Alaska, Puerto Rico and the Southeast, while the U.S. co-hosts the FIFA World Cup under dangerous summer conditions.
