A pea-soup fog blanketing much of B.C.’s south coast forced flight cancellations across the province Friday, and prompted multiple travel advisories.

Both WestJet and Air Canada advised travelers to check on the status of their flight before leaving for Vancouver International Airport, saying the weather may cause delays or cancellations.

Air Canada said flights to Nanaimo and Prince George would be impacted because of forecasted low ceilings and reduced visibility.

Harbour Air cancelled more than 20 float plane flights trips between Vancouver and Vancouver Island and the Gulf Islands because of the inclement weather. The airline warned of delays on flights scheduled to depart from Victoria’s Inner Harbour on Friday afternoon.

The airline says about one thousand passengers are affected. They say cancellations of this nature usually happen about five days each year.

Environment Canada predicted the fog would give way to a mix of sun and clouds Friday afternoon, but return later in the afternoon.
