Synopsis & Discussion
Forecaster: -S.DiBiase
The Thanksgiving Day holiday weekend and reduced dust causing activities should help keep the lower PM10 levels and so have a moderate dust risk for Saturday through Monday. A trough will move through the area Monday afternoon and bring breezy to gusty winds which will elevate the PM10 levels in the usual areas (Stanfield, Maricopa, and Eleven Mile Corner). However have keep the dust risk forecast in the moderate category since the winds and blowing dust aren't expected to be too strong. Transported particulates from southern California and western Arizona are expected to move into the area late Monday/early Tuesday and so the PM10 levels are expected to approach the health standard on Tuesday. Therefore have a high dust risk forecasted for Tuesday. Wednesday's high dust risk forecast is mainly for the Hidden Valley area and the typical morning dust activities which are expected to impact the monitor.
