Monday, October 12th 2020, 7:00 pm - Powerful wind gusts will batter coastal areas of B.C. and thousands of people are facing the possibility of power outages.
A low pressure system will rapidly intensify as it approaches the B.C. coast during the early morning hours on Tuesday and forecasters are warning that it could produce damaging winds and power outages. Vancouver Island will see the powerful gusts during the morning before they spill into the Lower Mainland and Fraser Valley in the afternoon and evening. Environment Canada has issued snowfall warnings for several high elevation regions as the wintry weather in these alpine areas continues. Details and timing, below.
- Thousands at risk of power outages on Tuesday due to strong wind gusts
- Winds will peak by Tuesday afternoon, gusts up to 100 km/h are possible
TUESDAY: POTENTIALLY DAMAGING WINDS, POWER OUTAGES POSSIBLE
A low pressure system will rapidly intensify during the early hours on Tuesday as it approaches northern Vancouver Island. The Weather Network meteorologist Tyler Hamilton warns that this powerful system will bring intense wind gusts up to 100 km/h, which could toss loose object or cause tree branches to break.
“Regions just south of the passage of the low can expect widespread power outages during the day on Tuesday. Previous lows of this intensity have knocked tens of thousands of customers off the power grid. Parts of the South Coast are particularly vulnerable to power outages with fall foliage hanging on in early October,” Hamilton says.
The strong winds will peak Tuesday morning and afternoon, with widespread gusts of 60-80 km/h. Winds will gust up to 100 km/h along the shores of Vancouver Island, where the risk of power outages is the highest.
The wind gusts will be less intense in Metro Vancouver, but there is still a low to moderate risk of power outages in this region. The rain will continue for most of the day for the coast and Lower Mainland, tapering off to showers in the evening.
Meanwhile, snow for the highway passes will continue, with some areas having the potential to see upwards of 10-20 cm of snow by Tuesday night. Freezing levels will be sitting at 1000 metres.
Snowfall warnings are in effect for Highway 3 - Paulson Summit to Kootenay Pass, Trans-Canada Highway - Eagle Pass to Rogers Pass, and Okanagan Connector - Merritt to Kelowna.
LATER THIS WEEK: UNSETTLED TREND CONTINUES
Beyond the long weekend, cooler and unsettled weather is expected to continue into mid-week, with daytime highs consistently in the mid-teens. However, forecasters are watching the potential for a period of warmer and drier weather during the second half of the coming week.
