PORTLAND, Ore. (KOIN) — The last king tides of the season will swamp the Oregon Coast from Jan. 11 to Jan 13.
King tides occur when the alignment of the sun and moon combine to add extra gravitational pull on the Earth, causing its oceans to swell. The third and final round of the unseasonably high tides will bring more coastal flooding and hazardous beach conditions to Oregon and Washington.
