Snow and ice are starting to fall on the Ottawa-Gatineau area Tuesday afternoon, with strong winds and rain also in the cards for some places.

Environment Canada has winter storm warnings in place for most of the region.

The storm is approaching from the south and as of noon had reached the Belleville area. Generally, the further north you are the more snow you're expected to get.

The warning for Maniwaki and areas west of Gatineau is for 25 to 35 centimetres of blowing snow starting late in the afternoon or early evening and lasting through the night.

For communities east of of Gatineau and ones to its immediate north — almost up to Gracefield — forecasters say to watch out for 20 to 35 centimetres of blowing snow and ice pellets at first.

There may then be a short period of freezing rain overnight before a change to rain in the morning.

There are the same expectations for Ottawa-Gatineau and surrounding communities east to Hawkesbury and southwest to Perth: late afternoon snow changing to freezing rain or ice pellets overnight.

When that change happens will affect the snowfall total, according to Environment Canada. The best analysis is 10 to 20 centimetres of snow.

Ottawa is forecast to rise from about –5 C at sunset to 0 C by morning and then keep going up to 4 C Wednesday.

There will be a winter parking ban in Ottawa for most drivers on most streets from 10 a.m. to 7 p.m. Wednesday.

Other areas west of Ottawa such as Pembroke and Bancroft could get it worse than the capital. Their snow range is 15 ot 30 centimetres and they have that risk of wind like neighbours across the Ottawa River.

The Sharbot Lake and Tweed areas are under a snowfall warning. They have a tighter snow window of 15 to 20 centimetres, with a risk of freezing rain as part of a change to rain overnight.

In and west of Kingston, there is a rainfall warning about 20 to 35 millimetres of rain starting around sunset. It follows five to 10 centimetres of snow.

There are Environment Canada advisories for those communities close to the St. Lawrence such as Cornwall and Brockville for five to 15 centimetres of snow and a risk of freezing rain. It's also expected to change to rain here.

If you have to travel, check 511 in both Ontario and Quebec and toggle on the options to check road conditions.

English and French school buses are cancelled across eastern Ontario, except for English buses in Ottawa. No changes were announced in western Quebec.

According to CBC's Climate Dashboard, snowfall records are in play Tuesday for Cornwall, Gatineau, Kemptville, Sydenham and Val-des-Monts. Belleville could break a daily rain record.

It had been a drier end to autumn and start to winter than normal.
