Ottawa police responded to about 50 crashes during the season's first significant snowfall in the National Capital Region on Monday.

Environment Canada issued a special weather statement at about 4 p.m. ET Monday, saying Ottawa can expect about 10 cm of snow to have fallen by the evening as a low pressure system caused rain and snow to fall across much of the southern Ontario.

By 3 p.m. about six centimetres of snow had fallen and five remained on the ground after some melting, said CBC climatologist Ian Black.

Another two to three centimetres were expected to fall by 7 p.m., Black said.

Police issued warnings

The early accumulation over the weekend and into Monday morning prompted a number of police forces to urge caution.

West Quebec regional police force the MRC des Collines tweeted that since Sunday there had been 22 collisions in their region, while the Ontario Provincial Police noted that there had been a built-up of snow in parts of their region.

Areas along with St. Lawrence River are expected to get rain mixed with snow, while areas north of Ottawa like Maniwaki won't get quite as much snow, according to CBC Ottawa climatologist Ian Black.

"So it looks like we're going to get the most snow right here in Ottawa right through the day today," said Black.
