Synopsis & Discussion
Forecaster: -S.DiBiase
A trough with associated cold front will bring breezy to gusty winds and blowing dust on Friday. The PM10 levels are forecast to approach and perhaps exceed the health standard, therefore the dust risk has been upgraded into the high category for Friday. Quiet weather returns for this weekend and so have low dust risks forecast for the weekend and early next week. Another low pressure system is expected next Tuesday along with breezy to windy conditions and some blowing dust. At this point the dust risk forecast for next Tuesday is moderate. Check back on Friday to see an updated dust risk forecast.
