Will The Valley See Its First Major Dust Storm of The Season This Week?

This week, the weather pattern has been favorable thunderstorm activity in southeastern Arizona on several days. And high-resolution forecast models have tried to forecast strong thunderstorm winds impacting the Valley from the south/southeast multiple times. However, those winds haven't always panned out.
Nevertheless, models are indicating the possibility of strong thunderstorms winds moving into the Valley later this afternoon. Therefore, there is a potential for a dust storm-perhaps a major one-to occur. We've thus issued a PM10 High Pollution Advisory for today.
Just a reminder: High Pollution Watches (HPW) are issued when there is a potential for a pollutant to exceed the federal health standard. An HPW may be upgraded to an High Pollution Advisory if there is a high probability for a pollutant to exceed the standard, or if it is imminent.
