We're over one week into the spring season but the weather in Ontario seems to be unaware of that.

Parts of the province are in for a multi-day snowstorm that could bring up to 40 centimetres of snow and hazardous driving conditions.

Here's what The Weather Network and Environment Canada want you to know about the upcoming weather event.

"A prolonged snow event is underway across northwestern Ontario as a sprawling storm creeps toward the region," says TWN. "Folks around Thunder Bay could see 30-40+ cm of snow over the next couple of days."

They note that travel could be hazardous, with Tuesday likely having the most impactful conditions.

"Expect widespread and long-lasting travel issues across the region, including along the Trans-Canada Highway."

Environment Canada issued a similar warning, noting that "poor visibility and rapid accumulation of snow could make travel difficult.

The snowy conditions could persist for over 60 hours in northwestern Ontario as they continue on from Sunday evening.

"Residents can expect periods of snow to continue straight through the day Monday and Tuesday before the system finally pulls away and tapers off into Wednesday," says TWN. "The heaviest snows will arrive during the day Tuesday as the storm reaches peak strength and snowfall rates approach 1-3 cm per hour north of Lake Superior."

By Wednesday morning, Thunder Bay and other areas could see anywhere from 30 to 40 centimetres of snowfall.

"Road closures are a real possibility," warns TWN. "Consider postponing non-essential travel until conditions improve."
