Nik Wallenda will have to deal with gusty winds as he attempts to cross the Little Colorado River Gorge without a safety tether late on Sunday.
Winds will generally be blowing from the southwest at 15 to 25 mph across the Little Colorado River Gorge, located east of the Grand Canyon in northern Arizona, late on Sunday.
Occasional gusts as high as 30 mph are expected, while dry weather and clear skies prevail.
The lack of rain may be welcome news to Wallenda, but the combination of Sunday's dry weather, low humidity and gusty winds is keeping the fire danger high across northern Arizona (as well as the rest of the interior Southwest).
Wallenda's walk across the Little Colorado River Gorge will take place at 8 p.m. EDT on Sunday evening, being aired on the Discovery Channel.
Wallenda will traverse a 1,400-foot-wide gap across the gorge, at height of 1,500 feet, on a wire that is only 2-inches thick, according to the Discovery Channel's official website on the walk.
No safety tether will be in place to attach Wallenda to the wire.
Wallenda is the seventh generation of the legendary Great Wallendas and started walking on the wire at four years of age.
