Only Renfrew County and the Bancroft area are spared from the warnings, which also cover Gatineau.

Snow started falling early in the afternoon around Belleville and is predicted to end Thursday morning.

Further east, including in Kingston and Ottawa, snow started later in the afternoon and is expected to stretch further into Thursday morning.

In a tweet Wednesday afternoon, OC Transpo listed a number of bus stops that were out of service because of road conditions.

On Wednesday night, the agency warned riders that transit services would likely be delayed Thursday morning.

And some flights out of Ottawa airport have been cancelled, so make sure to check before heading to the airport.

"There will be a significant impact on rush hour traffic in urban areas. Allow extra time to reach your destination," Environment Canada said.

Ottawa has a parking ban for most people on most streets from 10 a.m. to 7 p.m. Thursday. Kingston is piloting a similar ban until March.

Renfrew County and Bancroft have weather advisories for about 10 centimetres of snow Wednesday afternoon and night.
