A hazardous dust alert is out for Maricopa County and Pinal County today. Dust rolled in rapidly. Heavy winds pushed outflow air from the southeast into the Phoenix area. Visibility fell sharply across the Valley. That creates hazardous travel conditions for motorists on local roads and highways.
Monsoon storms moved in. Meteorologists said this happens as heat in Arizona remains above average. The National Weather Service reported strong winds all over the area earlier. Drivers need to reduce speed. Prepare for sudden plunges in how far you can see.
