Forecast Discussion: Updated Tuesday, July 22, 2014 10:45 a.m. ** PM10 HEALTH WATCH IN EFFECT WEDNESDAY, JULY 23, 2014 ** Mid level atmospheric moisture will make a return to the area on Wednesday and result in storm development over the mountains to the north and east. The steering flow will help move the storms off of the mountains and down into the valley locations of central Pinal County. Strong outflow winds (gusts to 30-35 mph) will create areas of blowing dust which will help the PM10 levels rise towards the health standard. Therefore a PM10 Health Watch has been issued for Wednesday. Anyone with respiratory and/or heart ailments should remain indoors during the mid/late afternoon and early evening hours when the winds and blowing dust will be at their peak. Check back on Wednesday for an updated air quality forecast. Forecaster – S. DiBiase
