Noctilucent clouds are rare. Noctilucent means “Light Shining ” in Latin. They are made out of ice crystals and are the ragged edge of polar mesospheric clouds. They also are known as night clouds because they only appear after the sun goes down. They are highest clouds in the atmosphere, usually 47 to 53 miles above the earth. Noctilucent clouds only appear in the summer and may be seen only be people between 50 and 70 degrees above and below the equator. In the US that would be very northern Alaska.

A water spout is an intense vortex that occurs pretty much over any body of water, but is extremely rare. It is a non-super cell tornado that occurs over water. They usually don’t suck up water unless they are associated with a mesocyclones. The water you see in most water spouts is condensation. While many water spouts form in the tropics, they can occur at higher latitudes such as Europe and the Great Lakes. Although rare, water spouts have been connected to “lake effect” snow. Water spouts have a five part life cycle: First the formation of a dark spot on the water surface, followed by a spiral pattern on the water surface, followed by the formation of a spray ring, then a development as a visible condensation funnel, followed lastly by their ultimate decay.
