Forecast Discussion: Updated Tuesday, April 24, 2018 ** OZONE HIGH POLLUTION ADVISORY (HPA) TUESDAY AND WEDNESDAY, APRIL 24-25, 2018 ** Yesterday both the ozone and PM10 health standards were exceeded as Apache Junction ozone reached 101 on the AQI scale and Hidden Valley PM10 reached 113 on the AQI scale. Thankfully this morning is starting off better at Hidden Valley as the hourly PM10 concentrations are only in the 100-300 ug/m3 range compared to over 1,000 ug/m3 yesterday at this time. Unfortunately for Apache Junction ozone as today is starting off at similar concentrations to yesterday. Favorable winds and above normal temperatures this afternoon will result in another ozone exceedance at Apache Junction. Therefore have increased today’s ozone health watch to an ozone High Pollution Advisory (HPA). Similar conditions tomorrow bring another expected ozone exceedance and ozone HPA. Anyone with respiratory and/or heart ailments should limit outdoor activities during the afternoon and early evening hours when the ozone levels are typically at their highest. Morning temperature inversions and light winds along with local dust activities in/around Hidden Valley bring continued daily chances for PM10 exceedances. Local dust controls will go a long way towards limiting PM10 exceedances at Hidden Valley. The PM2.5 levels will be elevated at Hidden Valley and are forecasted to be in the upper range of the moderate AQI category, though just below the health watch criteria.
