'Significant snowfall' possible for Ottawa on Wednesday

In a snowfall warning, Environment Canada calls for snowfall amounts of up to 15 centimetres, with more for some areas.

Ottawa is bracing for another significant snowfall that is expected to begin late Wednesday afternoon.

A snowfall warning is in effect. Environment Canada is calling for snowfall amounts of around 15 centimetres. Some local areas, mostly to the south of the city core, could see up to 20 centimetres of snow.

The snow is expected to begin as a Texas low moves into the area.

"Rapidly accumulating snow will make travel difficult," said Environment Canada in a statement. 

The winter storm is expected to continue into Thursday morning.

"Be prepared to adjust your driving with changing road conditions. Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow," Environment Canada says.

The storm is part of a system that is expect to affect a large swath of the population between Windsor and Ottawa.
