- Last night the second wave of moisture brought another heavy round of rain through the overnight. 42 hour totals are now over 100 mm for Vancouver Island & the Fraser Valley and 15-80 mm across metro Vancouver (yvr only 14 mm)

showers and mainly grey skies continue. A flash of blue may reward the most diligent of blue sky watchers but that's probably all.
Ducks & flowers rejoice..
- We are still very much in a pineapple express set-up, with that SE flow tapping into Hawaiian moisture & temps, but the moisture is coming in pulses..next one to move in this evening similar to what we say last night.
- Rainfall warnings remain in place for metro Vancouver/Fraser Valley and have now been re-issued for west Van Island for the heavy rain that will redevelop this evening and continue right through our Thursday.
- Additional amounts of 50 to 80 mm is forecast by Thursday night. For West Vancouver Island 100 to 120 mm is forecast by Thursday morning.
- Freezing levels will reach their peak today before starting a slow decent over the next several days..but very soggy conditions for the local mountains and mountain passes. Avalanche risk is high across most of the province.
- Finally, by early Friday, the stream is cut-off from the sub-tropical source and northwesterly winds will kick in ending the steady rain. However a cooler and unsettled Fri/Sat/Sun is still on tap ie sun/showers/cloud. Better chance of sun for Sunday & Monday.
- Meanwhile an Arctic front has pushed down into the Central British Columbia interior this morning is clashing with the Pacific SW flow to produce heavy snowfall for the central interior ie Prince George. 20 to 30 cm or higher are forecast by Thursday evening
