Several rounds of rain are on their way to British Columbia, as many parts of the province can expect as much as 200 mm through these final days of September. After the first round of rain tapers off by mid-week, another wave will track in by the end of this week and will come with the potential for powerful wind gusts and the threat for outages. Many places will see their normal rainfall for the entire month of September this week and some areas will even surpass their monthly records for September. More on the timing and impacts, below.

MONDAY AND TUESDAY: PERSISTENT RAIN WITH STORM PARADE

A soggy low pressure system is moving future ashore and the rainfall along the South Coast is expected to hold steady through Monday and Tuesday.

Locally, 50-75+ mm of rainfall is anticipated by Tuesday for the Metro Vancouver area and over 100 mm is expected for coastal Vancouver Island.

Freezing levels will remain quite high with this system, therefore high-elevation snow is not a concern.

WEDNESDAY AND BEYOND: MORE RAIN WITH COOL AND BLUSTERY CONDITIONS

Another moisture-laden system will move into the region on Wednesday, bringing a widespread soaking rain and gusty winds.

The gusts are likely to reach urban areas across the South Coast and for much of Vancouver Island. While it's tricky to say whether or not the intense winds will impact Metro Vancouver, some computer models are hinting at 60-70+ km/h, even 80+ km/h for areas inland, which heightens the threat for localized power outages.

Rain showers will linger through Thursday, with totals of 20-40 mm expected for the Lower Mainland and 40-80+ mm for the higher terrain and west coast of Vancouver Island.

Many places will see their normal rainfall for the entire month of September this week and some places will even surpass their monthly records for September.

"Vancouver has already seen close to double its average rainfall for the month of September and the final week of the month will bring close to their average rainfall for the entire month of September once again," says Dr. Doug Gillham, a meteorologist at The Weather Network.
