The so-called "king tides" made an appearance today in western Washington. It comes after the super wolf moon Sunday night.

You'll be able to see the king tides this week along the Puget Sound beaches. However, at this time, we're not expecting any additional coastal flooding. That's because higher pressure in our atmosphere is building.

The term "king tides" isn't scientific; rather, it's a colloquial name for these higher tides. They happen a couple times a year. King tides form when the moon's gravitational pull causes these tides, and because we know the track and speed of the earth and moon relative to one another, tides are predictable.

The moon has a larger influence on the tides than the sun, but the sun's gravitational pull can play a role as well. Due to this tidal force, earth's waters to bulge on the side closest and farthest from the moon, creating those high tides. In January, the earth is the closest to the sun. This is called perihelion, and it can give a boost to the tides, too.

This week, we don't just have the moon and sun playing a role in our king tides, we had low pressure offshore yesterday. That increased those tides.

The next couple of days in areas like Seattle, Olympia and Shelton, could see king tides to around 13 feet.
