Seattle may not have a white Christmas this year, but we will have a high tide Yuletide.

Starting Dec. 25, tides will be unusually high, thanks to the sun, moon and earth being aligned. Colloquially known as "king tides," these abnormally high tides occur about twice a year.

Tides are expected to reach 12.98 feet on at 7:26 a.m. Christmas day, 13.0 feet at 8:12 a.m. on Dec. 26 and 12.93 feet at 8:59 a.m. on Dec. 27 in Seattle.

High tide on Dec. 25 will follow a low tide of -3 feet, which means there will be a total swing of 15.9 feet that day.

A King Tide is predicted between this weekend and Christmas. Then you have today's #WAwind storm. This means you'll see more marine debris along our shorelines in the coming days.
