Hey fellow BC Astro

, I'm guessing the water came from the sky in the form of rain.
You may have noticed that we have gotten a little rain lately.
The water is probably leaking in though the top of your windshield. This may not happen during "normal" wet coast weather, but if your van has been sitting with snow on the roof any opportunity the water has to get in will be more apparent.
My garage was leaking during the snowfalls we've had lately but after I shoveled the snow off, it stopped leaking. Could be the same thing going on with your van.
Heard the lower mainland got more snow last.
