A strong frontal system will bring strong southeasterly gusts between 50 to 70 kilometres an hour to eastern Vancouver Island, the Sunshine Coast, and the Gulf Islands on Wednesday morning, Environment Canada said.

Winds are expected to diminish in the afternoon, but conditions will remain gusty throughout the day.

Global BC meteorologist Mark Madryga said this will be the strongest weather system that some areas have seen in months, and it has the potential to lead to localized flooding, more power outages, and possible ferry cancellations.
