Another blast of messy winter weather hit the South Coast Tuesday, with the Fraser Valley seeing the worst of it.

As much as five centimetres of snow was forecast to fall in the Fraser Valley and eastern sections of Metro Vancouver, according to snowfall warnings issued by Environment Canada.

Earlier in the day, the weather agency said as much as 10 centimetres of snow was possible, but the warnings issued Tuesday afternoon were more conservative.

Areas under the warning in the valley include Abbotsford and Chilliwack. The snowfall warning for Metro Vancouver includes Coquitlam, Maple Ridge, Surrey and Langley.

A frontal system will spread snow across the South Coast, the warnings say. Snow is expected to mix with rain during the evening, then change back to snow at night.

The snow will taper off early Wednesday morning, Environment Canada said.

While some parts of the region saw only rain during their morning commute Tuesday, it was a messy start to the day for drivers in the Fraser Valley.

"I guess 40 (km/h) was just too much," said Kyla Pleasure, as crews dealt with her stuck SUV. "It spun out and here we are."

Towing services say the accidents they witnessed were caused by drivers ignoring the conditions.

"It doesn't have to be on the ground. Sometimes when it snows, people, for whatever reason, they don't slow down, they don't make space and it creates a lot of work," said Frank Robertson, with F&W Towing.

Along Highway 1 in Langley drivers were mostly dealing with wet roads early Tuesday with a light mist of rain soaking the area. Wet snow started around 7:30 a.m. but traffic was moving well in both directions on the highway. Salting and brining trucks worked for hours overnight preparing roads for the morning rush.

In Chilliwack, a vehicle ended up in a water-filled ditch on Keith Wilson Road. Police are looking at weather and speed as possible factors, and said two people were taken to hospital. Their conditions are not yet known.

TransLink also took extra precautions to prepare for the Tuesday morning commute, including having anti-icing trucks on standby. There were no major issues on transit Tuesday morning.

Anticipating further snowfall Tuesday night, a City of Vancouver manager of street operations told CTV News drivers should not expect streets to be plowed right away.

"We wouldn't encourage anybody without the appropriate tires to be on the roads, so have those all-weather mud and snow tires, or those winter tires, if you are planning your commute," Erin Hoess said.

"And if you don't have those, plan an alternate way to get where you need to go, such as taking transit."

Hoess said the city spent the morning pre-salting the roads and preparing in other ways. When the snow falls, crews will first focus on priority routes - main arterials, hills and emergency routes - before moving on to roads less travelled.

She also reminded business and property owners that it is their responsibility to clear their sidewalks the morning after a snowfall. They must be cleared by 10 a.m.

Environment Canada says the next round of winter weather could come on Friday, with the rain-snow mixture expected in the Fraser Valley while Metro Vancouver may see some snow at higher elevations.
