PM2.5 Forecast for Beijing - Friday, April 12, 2013

Friday Forecast
After four days of good air quality, the weather conditions will be changing to again allow the PM2.5 pollution to accumulate.  Look for the accumulation to begin slowly after midnight, then progress more quickly after 5AM or 6AM.  We should start the day in the Moderate      range and pass through the Unhealthy for Sensitive Groups      range in the morning before progressing into the Unhealthy      range around late morning or early afternoon.  The PM2.5 levels should then hover in the Unhealthy range before worsening overnight and into Saturday morning.
