A storm coming from Alaska is expected to dump a fair amount of snow on Metro Vancouver.

According to Environment Canada, five to 15 centimetres "are quite possible" on the southern coast of B.C., especially on land farther away from the Strait of Georgia.

It will begin on Tuesday (February 13) afternoon and end on Wednesday (February 14) morning. 

Last winter, repeated snowfalls created havoc on Metro Vancouver roads and with SkyTrain and bus service.

But this year, TransLink is hoping for a better outcome.

In November, the regional transportation authority announced that it had introduced improvements in advance of this winter's snowfalls.

A de-icing product called glycol is now being emitted onto power rails to ensure that they continue conducting electricity to the SkyTrain's linear-induction motors in cold weather.

SkyTrain has also added brass to collector shoes on trains to help them cut through any ice that accumulates on the power rails.
