Strong winds threaten travel and power

The third of the atmospheric trio this week will feature a stronger low moving in from the Pacific.

The main impact from the system is the strong wind gusts, as the warm front moves ashore bringing in strong, southerly gusts.

Victoria Island took the brunt of the wind gusts overnight Tuesday, with gusts of 78 km/h recorded in Victoria. Higher gusts of 94 km/h were also recorded in Saturna, and 89 km/h in Friday Harbor.

In addition to the winds, more rain is forecast through Wednesday, with widespread totals of 30-50 mm expected. Intense rainfall rates of 10-15 mm an hour could impact some coastal regions.

In some of the harder-hit areas, 100+ mm is possible, which could result in localized flooding and water pooling on roads.

Significant, high-elevation snow

The heaviest snow of the fall season is expected in the Coquihalla and Allison passes across southwestern B.C, where close to 30 cm of snowfall is possible through Wednesday morning, but temperatures will be hovering near freezing so pass summits will get the most.

Long range shows freezing levels more typical of December, and highs in the mid-to-single digits, even reaching down to sea level by early next week.

Mountain pass travellers can expect tricky commutes on Wednesday, especially through the Interior where colder pockets of air will remain.

A brief break is expected with mostly dry conditions for Friday and into Saturday, but the next storm is expected to arrive as early as Saturday night and continue through Sunday night. This will be a colder storm with lower snow levels, and the potential for snow into the southern Interior, as well.

Cooler than seasonal temperatures will dominate through next week.
