Winds are blowing volcanic ash from Iceland towards Canada's eastern province of Newfoundland, and many airlines took preventative measures last night.
Numerous flights are canceled in and out of the airport in St. John's because of the threat of ash from the volcanic eruption that has grounded air traffic above Europe. A light fog this morning is adding to poor conditions.
The web site for St. John's International Airport lists most departing flights as either canceled or delayed up until 9 a.m. local time.
There's no word yet on whether the cancellations will be extended beyond that time, although all late morning, afternoon and evening flights are currently listed as on time.
Airport spokeswoman Marie Manning says Transport Canada is closely monitoring the affects on Canadian airspace.
Meanwhile, the Canadian Meteorological Centre says there is a low probability of risk because satellite imagery does not support ash presence in high concentrations.
CBC reports that no order has been issued to close airspace, and an airport spokeswoman said airlines would decide themselves whether to resume operations later today.
