Air Advisory Cancelled
By 250 News
The Ministry of Environment has cancelled the Air Quality Advisory for the city.
Just over one month into 2007, and we've already seen our second advisory of the new year. The first one occurred at the end of January and ran from Friday the 26, until the morning of Monday the 29th.
This second caution began this past Wednesday afternoon.
The Ministry says the weak weather disturbance that moved through the region last night made a difference. As of late yesterday afternoon 24-hour levels of fine particulate matter still exceeded the air quality objective of 50, but hourly levels had dropped and were expected to remain low.
Road dust was seen as a main contributing factor during this latest advisory. Meteorologist, Dennis Fudge, had said without precipitation to keep the dust down, it was becoming trapped in the airshed due to a stagnant weather system.
