High Streamflow Advisory: South Coast

ISSUED: January 21 2016 3:00 PM

The BC River Forecast Centre is issuing a High Streamflow Advisory for the South Coast including:

  • North Shore
  • Howe Sound
  • Sunshine Coast

A Pacific storm system is currently impacting the South Coast. Precipitation totals of 40 to 60 mm have been observed this morning at mountain weather stations through the North Shore, Howe Sound and Sunshine Coast region. Environment Canada is forecasting 50 to 70 mm of additional precipitation this evening and overnight, with the potential for higher amounts over higher terrain. Temperatures are expected to rise, with freezing levels reaching up to 2000 m or higher. Temperatures at the Squamish River Upper Automated Snow Station have risen 7 degrees Celsius since yesterday, and are currently hovering around 0˚C.

River levels have been rising in response to this morning's rainfall. Additional rapid rises are expected throughout the rest of Thursday, and overnight into Friday morning.

The public is cautioned to stay clear of rivers during rain events due to quickly flowing water and potentially unstable riverbanks.

The River Forecast Centre will continue to monitor conditions and will provide updates as conditions warrant.
