Forecast Discussion:

The dust risk forecasts will reach moderate on Wednesday through Friday as high pressure builds into the area. Early morning stagnation and local dust causing activities in/around Hidden Valley are expected to result in the typical morning spikes of PM10. A quiet weekend weather-wise is forecast at this time and so meteorological conditions may not change that much, therefore have a moderate dust risks forecast for Saturday and Sunday as well. Check back tomorrow for an updated dust risk forecast.
