WHIDBEY ISLAND STATION, Wash. — Residents of and near Whidbey Island witnessed a weather phenomenon on Tuesday as “wave clouds” lined the horizon.
Kelvin-Helmholtz clouds or fluctus clouds, as the formations are named, are very rare over Washington, according to KING 5 Chief Meteorologist Mike Everett.
The clouds look like literal waves in the sky, a series of rounded crests that are worthy of a double-take.
Often referred to as “wave clouds,” the clouds signal a difference in wind speed and density between two layers.
