FRASER VALLEY, B.C. — November 12, 2026. Drivers travelling through the Fraser Valley and across B.C.’s South Coast are being urged to plan for heavy rainfall, strong winds and the possibility of localized flooding on highways this week, according to a provincial traffic advisory issued on November 10.
The B.C. Ministry of Transportation and Transit says wet weather could leave standing water on roads, bring down debris and result in road closures with little notice. The advisory covers the Lower Mainland, Fraser Valley, Sunshine Coast and Vancouver Island.
Highway 1 in the Fraser Valley is among the routes of concern
The province identified three corridors that could be particularly affected:
- Highway 1: Through the Fraser Valley and Fraser Canyon.
- Highway 99: Through the Sea to Sky corridor and Pemberton Valley.
- The Malahat: Along with western coastal communities on Vancouver Island.
For people commuting between Abbotsford, Chilliwack, Langley and Metro Vancouver, the mention of Highway 1 makes the advisory especially relevant. The province is warning about possible flooding and closures; the notice does not establish that a particular highway segment is closed at the time of reading.
What is the province doing?
The ministry says highway maintenance crews have been clearing debris from roads and drainage systems, increasing patrols and preparing to respond if conditions deteriorate. Officials are continuing to monitor affected corridors during the storm period.
Motorists are also asked to give road-maintenance crews room to work and to be prepared for changing conditions.
What drivers should check before leaving
- Check the latest highway reports: Open DriveBC for current incidents, restrictions and closures immediately before travelling.
- Allow extra time: Heavy rain can reduce visibility and slow traffic even where a highway is officially open.
- Do not drive into floodwater: Water can hide road damage and may be deeper or faster-moving than it appears.
- Use headlights and increase following distance: Leave more room for braking on wet pavement.
- Watch for debris: Tree branches, pooled water and unexpected obstacles can appear after periods of wind and heavy rain.
How long will the conditions last?
The November 10 provincial advisory indicated that the unsettled weather could continue through the rest of the week. Conditions and restrictions may change quickly, so this article should not be used as a live road-status report.
