Dust Advisory issued for Quesnel. SHARE ON: Another Dust Advisory has been issued for Quesnel. It has kind of been on again, off again for the the past week. Gavin King is an Air Quality Meteorologist with the Ministry of Environment and Climate Change Strategy. “It is spring time. As with every year as the snow starts to melt and the traction material is on the road. We do tend to see a lot of lofting of particulate from the roads, and that results in the high course particulate, the PM10 numbers that we see.” King says there is a reason that they don’t just leave the advisories on until they are expected to come off for the long term.
