Parks Canada is advising visitors to P.E.I. National Park that surf conditions on the North Shore are dangerous.

The province has also issued cautions for its two North Shore parks, Cabot Beach and Jacques Cartier.

Rip currents may be formed along the shores due to high winds and the resulting surf, says Parks Canada. Entering the water is not recommended in the current conditions.

Rip currents form when waves break near the shoreline, piling up water between the breaking waves and the beach. Water rushes back out to sea in narrow channels, creating currents that are too strong to swim against.

Swimmers caught in a rip current should swim parallel to shore until they are out of the current. They will then be able to make it back to shore.
