The so-called "Royal Tides" appeared today in the western part of Washington. It comes after the moon moon on Sunday.
You'll be able to see the royal tides this week on the Puget Sound beaches. However, at this time, we do not expect any extra coastal flooding. This is because the higher pressure in our atmosphere is building.
The term "royal tides" is not scientific; rather it is a colloquial name for these higher tides. They happen several times a year. Royal tides are formed when gravitational attraction of the moon causes these tides, and since we know the path and speed of Earth and Moon in relation to each other, tides are predictable. but the gravitational attraction of the sun can also play a role. Due to this tidal force, the earth's waters swell from the country closest to and furthest from the moon, creating these tides. In January the land is closest to the sun. This is called perihelion and can give rise to tides and tides. The next few days in areas like Seattle, Olympia, and Shelton could see the tides of the king at about 13 feet.
