More heavy rain, winds prompt alerts in B.C., risk of flooding and outages

An active pattern spreading into B.C. this week brings good news for ski resorts, but bad news for folks at lower elevations. The storm parade continues, with several rainy systems and gusty winds across the south. Rainfall warnings and special weather statements are in effect for parts of the region.

Impact to travel is likely in areas that see the heaviest rain, with localized flooding and water pooling on roads a major threat. Residents are urged to clear storm drains of leaves and debris amid the ongoing miserable weather.

High winds may also cause tree branches to break, leading to disruptions and power outages through the mid-week mark.

Storm parade stays locked over B.C. this week

The first system was a deep Gulf of Alaska low that shoved a sprawling front across B.C. on Sunday, which brought gusty winds and locally heavy rain to the region. Our second system will be marked by onshore flow continuing into Monday with shower activity, and gusty winds.

Special weather statements were issued for sections of the South Coast, including Metro Vancouver, early Monday morning, with the risk for strong wind gusts and power outages.

The third of this atmospheric trio will feature a stronger low developing Tuesday evening in the eastern Pacific.

This system will drift toward the northern tip of Vancouver Island by Wednesday. Wind warnings will likely be issued with this low-pressure system.

Wind gusts of 70-90 km/h are possible across exposed coastal sections around the South Coast, including Greater Victoria and the Gulf Islands. Gusts between 50-60 km/h are forecast in Metro Vancouver, and up to 70 km/h for Delta.

Winds subside early Wednesday, but storm cleanup will likely continue.

The heaviest rainfall is expected to occur on Wednesday when 24-hour rain totals approach 100 mm on western Vancouver Island, and 50-75 mm across the Sea to Sky and North Vancouver.

As a result of the gusty winds and heavy rain, people can expect power outages, ferry delays and localized flooding.

There is high confidence for an unsettled pattern, but lower confidence on which coastal locations will see the worst of the damaging winds.
