UPDATE: Squalls Could Dump A Foot Of Snow

Environment Canada has ended snow squall warnings for north and east Lambton.

Meteorologist Geoff Coulson says persistent, strong northwest winds could dump a lot of lake effect snow in traditional snow belt areas.

“This could be quite a long lived event,” says Coulson. “We’re seeing some pretty big numbers being talked about in some of the forecasts. If these bands do lock in over a number of hours, we could be seeing some places picking up upwards of 30 to 40 cm by Wednesday morning. In fact some places could even get more then that.”

Coulson says whiteout conditions are possible in blowing and drifting snow with winds gusting up to 70 km/h.

Visibility will be suddenly reduced to near zero at times.

Motorists are urged to be aware of changing conditions and delay travel plans if possible.

An Alberta Clipper that sailed across the region last night caused slick driving conditions.

OPP reported over a dozen jackknifed trucks and numerous other collisions.

School buses in Zones 1, 4, 5, 6, 7 and 8 were cancelled and Hillside School in Kettle Point is closed.

Toronto’s Pearson International Airport had a handful of flight delays and cancellations this morning.

Air Canada had warned that the snow could cause flight delays at Pearson and at the Ottawa International Airport.
