Environment Canada says enhanced wave activity and high winds could push storm-surge water levels above tides in parts of coastal B.C. from 10 a.m. to noon.
The Story
Deluged residents in coastal British Columbia are facing a renewed flooding risk even as some rainfall warnings have eased, with Environment Canada warning of a storm surge that could raise sea levels along the shore.
The agency said the surge is expected to affect low-lying and exposed coastal areas of Metro Vancouver, southeast Vancouver Island and the southern Gulf Islands. It said water levels surpassing tidal predictions would be driven by high winds and "enhanced wave activity," and are expected to peak from 10 a.m. to noon.
The storm surge warning comes after flooding triggered by a parade of storms this week. Most rainfall warnings covering the region were lifted on Thursday, though two yellow warnings remain in place for western and inland Vancouver Island.
Those warnings say heavy rain is expected into late this afternoon, with the highest rainfall expected near Zeballos and Tahsis in northwest Vancouver Island. The drenching has brought more than 300 millimetres of rain to parts of southwest B.C.
The village of Pemberton, about 150 kilometres north of Vancouver, remains under an evacuation alert, with parts of the community under evacuation order.
Evacuation orders have also been imposed by the Lil'wat First Nation and in Zeballos.
