High Streamflow Advisory

High Streamflow Advisory for Vancouver Island, Sunshine Coast, Howe Sound, and Squamish Valley.

A series of Pacific storms are expected to impact coastal British Columbia over the early part of this week with moderate to heavy rainfall anticipated on Tuesday afternoon and Wednesday (October 17 and 18, 2023).

Currently the Squamish River Valley is seeing high stream flows and the community is asked to avoid the Mud Creek area as it is unpassable.

Fast-flowing rivers pose increased risk to life safety. Be alert to road conditions, check DriveBC for current conditions, and do not drive through flooded areas.
