HAWAII – The largest swells in a decade are hitting Hawaiian north shores.
Giant waves (some up to 50 feet high) were rolling into the north beaches of what some consider the surfing mecca of the world.
A high-surf warning was issued for much of the state.
The National Weather Service says a large, powerful storm with hurricane-force winds is spinning north of Hawaii, causing a 50 foot high swell.
The islands have not experienced waves like this since 2004.
Authorities said the huge waves and dangerous currents will make it extremely dangerous not just to be in the water, but even to approach the shoreline.
The waves are expected to subside by Friday morning.
