Cirrus clouds
Cirrus (Lat. 'wisp of hair') is a type of cloud.
Cirrus clouds are composed of ice crystals and shaped like hairlike filaments. They are formed at an altitudes above 16,500 feet. If there are many cirrus clouds in the sky it may be a sign that a frontal system is approaching. Cirrus clouds can also be the remnants from a thunderstorm.
