Overview

  • Environment Canada ended its weekend coastal flooding bulletin on Monday after peak water in Vancouver reached nearly 5.4 metres around 7:30 a.m. Sunday.
  • A new frontal system has prompted yellow rainfall warnings for Metro Vancouver, with 30 to 40 mm forecast centrally and 50 to 70 mm near the North Shore mountains.
  • Higher elevations could see snow where freezing levels drop to roughly 300–500 metres, though forecasters note low confidence in exact snow levels.
  • Significant snowfall is expected on local mountains, and separate yellow snowfall warnings call for 15 to 25 cm along the Sea to Sky and Whistler corridor.
  • Avalanche Canada has downgraded some areas from high to considerable danger, but considerable risk persists from the coast to Pemberton and in multiple other B.C. mountain regions.
