SAFFORD, Ariz. – Coronado National Forest officials were warning that rainfall from monsoon storms could cause flooding on Mount Graham, a popular recreation area in southeastern Arizona.

Officials said flooding on Mount Graham could be spurred by runoff from an area where vegetation was burned off during a 2017 fire. There was potential for water, soil, rocks and woody debris to move downslope swiftly and without warning.

State Route 366, also known as Swift Trail, is the only highway up the mountain, and forest officials said emergency road closures were possible if there was flooding.

They said road-clearing could take hours and that drivers should be prepared for temporary delays.

Mount Graham is near Safford and 72 miles northwest of Tucson.
