Environment Canada has issued a snowfall warning for Greater Victoria, saying more winter weather is on the way after the region saw up to four centimetres of snow fall Wednesday afternoon.

Heavy flakes started falling around noon and stuck to the ground, resulting in a thick layer of snow blanketing the ground by the late afternoon.

Another five centimetres of snow is possible into Wednesday evening before easing off, Environment Canada said.

It's warning motorists to "prepare for quickly changing and deteriorating travel conditions," and to brace for increased rush-hour traffic on routes like the Trans-Canada Highway.

Drivers reported an accident on the highway near Thetis Lake Park and posted a photo of two vehicles in a ditch between the northbound and southbound lanes.

Drive BC also reported around 5:30 p.m. that the right southbound lane of the Malahat Highway was shut down near the Malahat summit due to a vehicle incident. The accident was cleared and the lane reopened before 7 p.m.

The snow also caused some travel disruptions for Harbour Air passengers. At around 3:15 p.m., Harbour Air cancelled the remainder of its flights at all terminals, citing limited visibility due to snow.

Ironically, the City of Victoria was forced to cancel an emergency preparedness workshop at city hall due to the heavy snowfall. The city said it would reschedule the workshop for a future date.

While no warnings were issued for other parts of Vancouver Island, Nanaimo was also forecast to receive two to four centimetres of snow, with flurries ending late Wednesday evening.

Further north, Campbell River was also expected to see snowfall into the evening.

After Wednesday's snowfall, Environment Canada says sun is in the forecast for Thursday with a high of four degrees in Victoria.

Daytime temperatures will remain above freezing for the rest of the week in Victoria and Nanaimo, with rain in the forecast over the weekend.
