We will continue reporting on poor air quality days, especially PM 2.5 days, which are increasingly a problem in the cool and cold days of fall and winter.
Seasonal suspension of daily ozone forecasts as of 9/17; Daily particle pollution forecasts continue year-round
As we approach fall, days grow shorter and temperatures cool. And ground-level ozone concentrations remain in the good or, at worst, moderate range. As a result, the Virginia Department of Environmental Quality will suspend daily ground-level ozone forecasts for Richmond, Hampton Roads, Winchester and Roanoke as of September 17th (the last ozone forecast will be issued on September 16th). However, daily air quality forecasts for particle pollution will continue through the fall, winter and spring for Richmond, Hampton Roads, Roanoke and Winchester. They will continue to be emailed daily and posted at http://www.deq.virginia.gov/Programs/Air/AirQualityForecasting.aspx. Ozone forecasts for Richmond, Roanoke, Winchester and Hampton Roads will resume in Spring 2015 when warmer, ozone-conducive weather returns.
