A weather system moving into Arizona could spawn blowing dust across the Phoenix area on Friday, prompting concern from the National Weather Service and Department of Public Safety.

Strong winds, rain, possibly thunderstorms and blowing dust are expected for the Valley during the weekend because of a low-pressure system that is expected to arrive Friday afternoon, according to the National Weather Service.

The system will bring cool temperatures, and heavy winds are expected to create dust storms around the Valley.

Winds are expected to be at their strongest during rush hour on Friday.

The Department of Public Safety is urging drivers to be cautious while commuting during these expected storms. Visibility could be low, creating dangerous road conditions.

The Department of Public Safety asked that drivers stay off the interstate, if possible. If drivers must be on the freeways, officials suggest driving slowly with headlights lights on during low visibility and carrying emergency items in case drivers are stranded.

The warning comes after a two serious wrecks on Interstate 10 several weeks ago.

A semitruck and two other vehicles were involved in a dust-related crash on Sept. 27 on Interstate 10 near Picacho Peak, causing the interstate to close for several hours and one woman to be taken to the hospital.

On Oct 5, there was a 16-vehicle collision on Interstate 10 between Phoenix and Tucson, caused by low visibility from a dust storm. A Texas man died in the pileup when the Honda sedan he was a passenger in struck a large freight truck before sliding under a commercial vehicle.

Thursday is expected to be breezy with a high near 72 degrees and a low near 57. Friday is forecast to be windy with a high near 70 degrees and possible showers into the evening.

Temperatures cool off significantly Saturday as the high hits 54 degrees, with a low of 46 degrees. Rain is possible Saturday morning. Sunday's forecast is a high near 58 degrees and mostly sunny.

Monday sets the stage for a week of temperatures in the high 50s and low 60s with a high near 57 degrees and a low about 45 degrees.

Tuesday is forecasted to be mostly sunny with a high near 60 degrees and a low of about 47. Wednesday's high will be about 67 degrees.
