LORDSBURG, N.M. (AP) — High winds and blowing dust are causing problems across the Southwest. It's causing a closure on Interstate 10 along the New Mexico and Arizona border. State transportation officials in both states say they're diverting traffic off I-10 to Highway 70, at San Simon, Arizona, and Lordsburg, New Mexico. No timeline was given for when the roads would reopen. In southern Nevada, Clark County's Department of Air Quality issued a dust advisory in effect through Saturday evening.
