Senior meteorologist Kristi Gordon has an update on drought levels in the province and your Thursday, Nov. 9, 2023, forecast for Metro Vancouver and British Columbia.

Environment Canada says a “vigorous frontal system” expected to cross British Columbia’s South Coast is bringing with it heavy rain and wind for some regions of the province, and snow for others, until at least Saturday.


The agency has issued multiple warnings for Metro Vancouver, saying 50 to 70 millimetres of rain is expected to hit the Fraser Valley and the North Shore and northeast regions beginning tonight.


Forecasters say the rain should taper off over parts of Metro Vancouver on Saturday morning but persist in the Fraser Valley until the evening.


Wind warnings also cover much of the region as well as portions of Vancouver Island and the Sunshine Coast, with gusts of up to 90 kilometres per hour before easing Saturday morning.


Environment Canada says wind could cause power outages and downpours could be heavy enough to lead to flash floods and water pooling on roads.


A special weather statement covering portions of the Coquihalla and Trans-Canada highways as well as Highway 3 through the mountains says 20 to 30 centimetres of snow is expected by Sunday morning.

The province is urging people to prepare for stormy weather and heavy rain across the Fraser Valley, Vancouver Island, and the Lower Mainland over the next week.


A forecast from Environment and Climate Change Canada shows an atmospheric river is on the way to the area.


“Narrow bands of heavy precipitation such as this are common in British Columbia and many occur every year, most frequently in the fall and winter,” the province said.


As a result, “heavy to very heavy rain” is expected to hit the Fraser Valley, the Lower Mainland, the Howe Sound, and the western part of Vancouver Island on Monday and Tuesday. The province says this will be the “peak of the storm.”


CityNews Meteorologist Michael Kuss explains the rain usually comes in waves at this time of the year, and that’s what we’re seeing.


“We were talking about how dry it’s been this year, but we’re into the wet weather now, and that lasts at least into the middle of next week,” Kuss said.

“I wouldn’t be shocked, for the Lower Mainland and in a fairly widespread way, for 150 millimetres over this five day stretch.”

Kuss adds that while this kind of weather is generally seasonal, it’s the lack of precipitation we’ve had that makes it feel like a switch has been flipped.


“The series of storms started coming through the area Thursday, and some of these storms could bring 40 to 50 millimetres individually.”


When it comes to snow, the province says it is unsure how much will hit affected areas over the course of the storm.


Those in low-lying areas are asked to prepare for possible flooding. People in affected areas are also advised not to drive or walk in flood water, as “rushing water can carry away most vehicles.”


The province adds that the River Forecast Centre will monitor the weather and issue any additional advisories and warnings as needed.


Kuss explains the heavy rain, coupled with the sustained lack of precipitation this year, will result in some localized flooding, high streamflow advisories, and even potentially some landslides in the Interior.


“We’re watching out for that, especially with the fire-scorched earth at a lot of locations,” Kuss said.




...except it's already started falling on my head, forget Monday/Tuesday.

Special weather statement for Metro Vancouver issued Saturday; flooding, landslides, power outages possible

Environment Canada issued a special weather statement for Metro Vancouver and surrounding areas Saturday morning, saying incoming storms will increase the potential for flooding, water pooling on roads, power outages, and possible landslides.


The statement applies to Metro Vancouver, the Sunshine Coast, and parts of Vancouver Island.


Environment Canada meteorologist Armel Castellan says residents should expect “long duration” rainfall events Saturday and Sunday.


Castellan says although it won’t be as bad as the recording-breaking 2021 floods that washed away bridges and prompted landslides that killed five people, people still need to stay away from fast-moving rivers this time.


The weather service says it isn’t sure where the worst of the storm will be felt or exactly when the heaviest rains will fall.


“The heaviest rainfall is expected to occur between Sunday night and Monday,” the statement says. “There will be periods of lighter rain between the storms, but it is the cumulative effects of the storms that is likely to be impactful.”


The storms are bringing warmer temperatures, and mountain snow melt is contributing to the flood risks. The weather service says vulnerable areas such as burn scars are particularly vulnerable to landslides due to heavy rain falling on surfaces that are already saturated.


Strong winds will mean an increased risk for power outages due to the potential of falling tree branches.


Meanwhile, a flood watch issued by B.C.’s River Forecast Centre Thursday remains in place as rain pounds the South Coast Saturday.


The watch applies to the Sunshine Coast, Sea-to-Sky, North Shore mountains, Fraser Valley, and Vancouver Island.


On Friday, Environment Canada issued a rainfall warning for Metro Vancouver, including the North Shore, Coquitlam, Maple Ridge, and Howe Sound, saying a total of 60 to 90 millimetres of rain is expected to fall between Friday evening and Saturday overnight.


The River Forecast Centre says between Saturday and Wednesday, a series of “potent” storms is expected. Up to 250 mm of rain could fall during that time in Metro Vancouver, with some localized areas having the potential to receive up to 400 mm.


“Current forecasting is indicating the strongest atmospheric river event making landfall on Monday, with the potential for additional rainfall in the middle of next week,” the River Forecast Centre said in a news release Thursday. “The heaviest rainfall is currently forecast over West Vancouver Island and the Coast Mountains.”
