ISSUED ON: Tuesday, June 20, 2022

This proactive, air quality forecast is part of a statewide effort to engage communities in areas not meeting health-based standards, so they can make informed decisions and take precautionary steps to protect themselves and their families.

ADEQ produces this forecast, valid for areas within and bordering Hayden, Monday through Friday. For details about this forecast and to learn more about ADEQ statewide forecasting, visit: azdeq.gov/forecasting.

What has our attention right now is that models are hinting at the possibility of the Valley's first dust storm(s) of the season. Strong thunderstorm outflow winds may be possible each day Tuesday through Thursday. And Tuesday and Wednesday may see those winds out of the southeast--in other words--where the greatest dust source is.

ADEQ Meteorologist

As always, we'll have to take this one day at a time, as the smaller details of monsoonal thunderstorms are difficult to pin down in advance.

But for now, we have raised the dust risk to High for Tuesday and Wednesday, and Moderate for Thursday.
