Forecast Discussion: Updated Monday, October 23, 2017 ** PM10 HEALTH WATCH IN EFFECT TUESDAY, OCTOBER 24, 2017 ** High pressure over the western United States will bring near record to perhaps record high temperatures today and Tuesday. A pressure gradient will set up Tuesday and the first half of Wednesday. The pressure gradient will cause breezy to gusty easterly to northeasterly winds on Tuesday and Wednesday before diminishing later Wednesday. The easterly to northeasterly winds are usually not good wind directions for Hidden Valley as that typically transports the dust created locally over to the monitor and ends up causing elevated PM10 levels. Additionally the strength of the winds may pose a blowing dust hazard for other monitoring locations (i.e. Stanfield, Eleven Mile Corner). Therefore as a precaution have forecasted PM10 levels approaching and perhaps exceeding the health standard. A PM10 Health Watch is being issued for Tuesday due to blowing dust elevating the PM10 levels and may be extended into Wednesday. Anyone with respiratory and/or heart ailments should reduce outdoor activities during periods of blowing dust. Stay up to date with current air pollution levels by checking out the near real-time PM10, PM2.5 and ozone levels online at http://www.pinalcountyaz.gov/AirQuality/Pages/AirQualityReport.aspx. The PM2.5 levels will follow behind the PM10 levels and be in the range of mid to upper moderate on the AQI scale. The ozone levels are expected to be in the upper good range on the AQI scale: Forecaster: S. DiBiase
