Massive ocean swells hammer coast

With clear skies, City and coastside residents could still hear thunder today and in the next several days as huge ocean swells pound the coast.

Swells generated by low pressure system in the Gulf of Alaska could reach more than 30 feet as they make their way to shore, according to weather and information from the Maverick’s Surf Contest.

The low pressure system is generating a large amount of wind in the Gulf, and “those strong winds generated a pretty good swell headed our way,” said Steve Anderson, a forecaster with the National Weather Service.

Anderson said swells would reach in excess of 20 feet in height through Wednesday morning, and according to tracking service StormSurf, swells Wednesday could reach to more than 30 feet as they approach land.

Those swells and the sheer violence they produce when slamming into the rocky cliffs or sandy beaches often draw spectators. Anyone who does head to the beach to see the show should keep a safe distance from the water to avoid being washed out into the water.
