A winter storm is expected to bring a significant amount of snow to Ontario starting Tuesday night, but forecasters don’t know which communities will be the worst hit.
According to a special weather statement from Environment Canada, there is still “a great deal of uncertainty” about the storm because the temperature will be fairly close to the freezing mark, meaning some regions may see more rain or wet snow that won’t accumulate.
The GTA and communities to the west and northwest of Lake Ontario may see snowfall amounts of up to 15 centimetres through Wednesday morning, Environment Canada said Monday.
However, the snowfall amounts could be considerably less if the snow mixes with rain, according to the special weather statement.
Meanwhile, the latest weather models suggest that the precipitation will begin Tuesday afternoon as rain south of a line from Sarnia to St. Catharines.
The precipitation will change over to wet snow by early Tuesday night and snow will then spread northeastward to south central Ontario by late Tuesday night and into eastern Ontario by Wednesday morning, Environment Canada said.
