PM2.5 Forecast for Beijing - Thursday, July 25, 2013
Wednesday's good air quality should stick around for a bit longer on Thursday. We should spend the morning hours at Moderate or Unhealthy for Sensitive Groups, but by sunrise we may begin to see the beginning of an upward trend in PM2.5 levels. This should be a slow increase, but we could move up into Unhealthy as early as mid-morning. By evening, there is a good chance that we will have left Moderate behind and will be moving steadily toward or further into Unhealthy.
