When: This evening though Wednesday evening.

I would just like to point out that we are not (yet) experiencing a very rainy December.

Rainfall since Dec. 1:

99.0 mm Coquitlam-Burke Mountain (monthly normal [2014-2024]: 375.1 mm)
55.4 mm Abbotsford (monthly normal: 179.8 mm)
46.8 mm Vancouver YVR (monthly normal: 158.3 mm)

So that's totally NORMAL so far.

Many seem to forget that December is the 2nd wettest month of the year and that the averages are very high.

Depends on location. I'm at just under 90 mm which means I'm on track for about 350 mm. Normal is 211 mm.

The long range ensemble makes some really nice changes. Storm I'd love to say Dec 19 but I'm thinking a little later still, personally.

One saving grace is we won't have the snow melt we had in November 2021.

Looks like the GEM is giving us snow next week already.
