Short-Term Forecast:

Monday-Wednesday:

An atmospheric river will slam into the BC coast Tuesday/Wednesday and bring over a meter (3.2 feet) of snow to the coastal mountains.

Snow will begin Tuesday morning as a trough of low pressure transports moisture into the coast.

This will continue through the day Tuesday and into Wednesday, moving from north to south.

By Wednesday evening, snow will taper off as the transport of moisture moves south into the US.
