Flood Risks Rise as Atmospheric River Hits B.C., Bringing Rain, Snow and Wind
Heavy rain up to 250 mm, strong winds, and snowmelt are raising flood risks across coastal and interior British Columbia, officials say.
- On Monday, March 16, 2026, an atmospheric river arrived in British Columbia, triggering flood watches and weather warnings across the province. The River Forecast Centre issued high-streamflow advisories for affected coastal regions.
- Multiple pulses of precipitation are expected through mid-week, with rising temperatures creating snowmelt that will compound flooding risks. The centre warns that increasing run-off is particularly forecast for areas already saturated by heavy rain.
- Environment Canada forecasts up to 250 millimetres of rain by Wednesday in some areas, with wind gusts reaching up to 110 kilometres an hour across the central coast and Vancouver Island. Warnings span rain, wind, and snowfall.
- Travel faces significant disruption as snowfall hampers transportation routes and winter storm warnings take effect for ski resort community Whistler. Up to 20 centimetres of snow is expected to fall before conditions shift to rain.
- Flood risks in coastal regions are likely to rise as the atmospheric river moves across the province throughout the week. Residents should remain alert to changing conditions and official updates.
