High streamflow advisory for Howe Sound

A High Streamflow Advisory is in effect for Howe Sound, Sea to Sky, North Shore Mountains, Metro Vancouver, and the Fraser Valley.

Temperatures are forecast to increase considerably compared to the recent extended cold weather and snowfalls.

Additionally, moderate to heavy rainfall is expected for Tuesday and Wednesday. The combination of low elevation snowpack, warming temperatures and heavy rainfall will result in rapid rises for creeks and rivers, especially at low and mid‐elevation watersheds on the coast.

It could result in minor to significant flooding.

Rivers are expected to begin increasing on Tuesday and likely peak Wednesday or Thursday. The storms are still several days away, so the exact location and intensity of heaviest rainfall is still uncertain. Areas that experienced flooding last year may have added vulnerabilities due to erosion and higher baseflow conditions.
