Up to 250 millimetres or more could fall in parts of Vancouver Island as flood watches cover much of the coast
VANCOUVER, Nov. 10, 2026 — An intense frontal system is bringing a new round of heavy rain to coastal British Columbia, prompting orange rainfall warnings and broad flood watches after earlier storms left saturated ground and widespread damage.
Environment and Climate Change Canada forecasts 150 to 200 millimetres of rain across inland Vancouver Island through Wednesday night, with more than 250 millimetres possible locally. An orange warning represents high expected impact and high forecast confidence.
Howe Sound and the Sea-to-Sky corridor could receive 120 to 160 millimetres, possibly more. Yellow rainfall warnings call for 60 to 100 millimetres on Metro Vancouver’s North Shore, with totals near 120 millimetres in the mountains.
Whistler could receive 50 to 100 millimetres. The Sunshine Coast and eastern Vancouver Island from Nanoose Bay to Campbell River are also forecast to receive 50 to 100 millimetres.
Flood watches replace earlier advisories
The B.C. River Forecast Centre has issued flood watches for the South Coast, Vancouver Island, the Central Coast-Kingcome region and northern Fraser Valley.
A flood watch means rivers are rising and may approach or exceed their banks. Flooding could occur in adjacent areas. It is more serious than a high-streamflow advisory but remains below a flood warning.
A separate high-streamflow advisory remains in effect for the Pemberton Valley.
The heaviest rain is expected Tuesday and Wednesday, with moderate precipitation continuing into Thursday in some areas. Environment Canada says localized flooding is likely, some roads could become impassable and landslides are possible on steep slopes, deforested terrain and recent burn scars.
Region still recovering from weekend storms
The approaching rain follows a destructive sequence of coastal storms.
The Canadian Press reported that a falling tree killed a driver in Surrey on Saturday. A 78-year-old pedestrian also died after being struck by a vehicle during a Vancouver downpour Friday; police noted the weather conditions, but the collision should not be characterized as a confirmed direct weather death without an official finding.
Earlier windstorms temporarily interrupted electricity service to about 415,000 BC Hydro customers. A canoeist reported missing in stormy waters off northern Vancouver Island remained unaccounted for in the latest published report.
Safety and travel
Residents should stay away from rivers, creeks and culverts and avoid walking or driving through floodwater. Travellers should check DriveBC before leaving and be prepared for sudden road closures, poor visibility, debris and standing water.
People in landslide-prone areas should follow local emergency instructions and watch for new cracks, leaning trees, unusual water flow or rumbling sounds.
