The strong winds yesterday did kick up more dust than expected, causing PM10 to reach the Moderate AQI category. Looking ahead, winds will still be a little breezy today and tomorrow, but shouldn't be as strong as yesterday. After tomorrow, winds are forecast to be light. Overall, we are forecasting PM10 levels to return to the Good AQI range today and remain there through the forecast period.
