Watch out for sneaker waves on the coast this week


A storm in the Gulf of Alaska is creating swells

PORTLAND, Ore. (KOIN) — There is an increased risk for sneaker waves on the Oregon coast both Tuesday and Wednesday.

The primary reason for the risk is a storm in the Gulf of Alaska that is creating a 5-7′ swell by the time it reaches our coast.

While it’s hard to predict exactly when sneaker waves will happen, hence the name, these waves become more likely when you have an increasing swell following a lull in wave action. Monday’s waves were ankle-biters.

“This, coupled with exaggerated high tides during the new moon phase, and all of a sudden you have no more beach to run away from sneaker waves and you’re playing hopscotch with log debris,” said KOIN 6 Chief Meteorologist Natasha Stenbock.
