A fresh Pacific storm has knocked out electricity to more than 100,000 BC Hydro customers across the Lower Mainland and Fraser Valley, compounding the effects of last week’s flooding and making this the utility’s third major weather-related outage in a single week.
As of early Wednesday, outage maps showed dense clusters of interruptions from Vancouver through Surrey and along the Fraser Valley corridor, with additional cuts reported on Vancouver Island and the Sunshine Coast.
The system arrived on the heels of intense rain and flooding that forced states of local emergency, highway closures and evacuations in parts of the Fraser Valley, leaving infrastructure and communities with little time to recover before the next hit.
Environment Canada has issued a special weather statement for the region, warning that strong winds with gusts up to 80 km/h are expected Wednesday morning over the South Coast. In central and eastern sections of the Fraser Valley, including Chilliwack and Hope, forecasters say gusts could reach 100 km/h as the frontal system sweeps through.
The combination of saturated soils from recent flooding and renewed high winds increases the risk of trees uprooting or snapping onto power lines, roadways and structures. Environment Canada has cautioned that winds could cause tree damage, outages and travel delays, and is advising residents to secure loose objects and avoid downed lines.
On Monday, a woman in Chilliwack was killed by a falling tree in a local park, underscoring the heightened risk in riverside and low-lying communities where root systems have been stressed by prolonged heavy rain.
BC Hydro is framing Wednesday’s event as the third major weather-related outage episode of the week, following an earlier storm that left roughly 24,000 customers without power as winds tore through the South Coast.
The utility has been cycling crews through restoration work while new outages appear elsewhere on the network, particularly along exposed river valleys and forested corridors. In some communities, emergency officials have reported that localized blackouts are tied to both fallen trees and transmission circuit issues, not only damage on smaller distribution lines.
Road infrastructure is also under pressure. A 60‑kilometre stretch of Highway 3 southeast of Hope remains closed after successive storm systems and high flows compromised conditions in the corridor. With more strong winds expected, transportation operators face the risk of additional debris, rockfall and visibility issues.
While the wind grabs immediate attention, hydrological risk remains elevated. Parts of Abbotsford, Chilliwack and Port Coquitlam are under flood warning, meaning river levels have exceeded or are expected to imminently exceed banks, leading to overland flooding.
Most of B.C.’s South Coast remains under flood watch status, with forecasters expecting river levels to approach or possibly exceed bankfull as further rainfall and snowmelt work through the system.
