Blowing sand prompted the closure of two major thoroughfares in Palm Springs Friday.
North Indian Canyon Drive and Gene Autry Trail were expected to be closed at the Whitewater Wash until at least the end of Saturday, when winds are forecast to die down.
Officials said the heavy winds tossed piles of sand onto the roadway and airborne dust obscured visibility, making for dangerous driving conditions.
The National Weather Service issued a wind advisory for the Coachella Valley through 9 p.m. and cautioned that gusts could reach up to 50 mph.
State Route 111 and Vista Chino remained open at the wash.
