This statement is in effect for parts of the coast due to the following hazard(s):
- Higher than normal water levels


Elevated ocean water levels accompanied by strong winds and waves are expected, exceeding highest astronomical tide.

What:
-Possible coastal flooding due to storm surge coinciding with high tide.

When:
-Saturday near noon (10 am to 2 pm) and Sunday near noon (10 am to 2 pm).

Where:
-Coastlines along west Vancouver Island.

Additional Information:
A deep low-pressure system will track across the region this weekend, bringing strong south to southeast winds to Vancouver Island before shifting to southwesterly winds. These southwest winds will generate large waves along the west coast of Vancouver Island, particularly on Sunday. The timing of the strong onshore winds and high waves with high tide may result in water levels potentially exceeding the highest astronomical tide.

Minor coastal flooding is likely along exposed shorelines especially in the low-lying areas.

Roads and walkways maybe difficult to navigate due to flooding and/or debris, such as driftwood and rocks.

Coastal erosion is possible in sensitive areas, such as tidal flats, estuaries, dunes, beaches and barrier islands.
