This animation of GOES-08 visible imagery shows the rapid development of smoke plumes across central Quebec on 06 July 2002. Hourly surface report data (in metric units) is also plotted on the imagery. Individual smoke plumes eventually merge into one large, thick smoke pall that continues to be advected southward. Early in the loop sequence, thick smoke is also seen across much of southwestern Quebec, eastern Ontario , and James Bay -- this smoke resulted from burning activity in central Quebec on the previous day. Extensive cloudiness (brighter white) is evident across southeastern Quebec during this period, while more clouds approach the region from the west during the afternoon hours. The thick smoke can also be seen to suppress cumulus cloud formation as it was transported southward across the region.
