The sky moves sideways
"Cirrus uncinus" cloud formations (derived from Latin, meaning "curly hooks") - Also known as mares' tails.
They are good indicators that precipitation, usually rain, is on the way.
These clouds occur at very high altitudes, at temperatures around −40 to −50 °C
The tails of the cirrus uncinus clouds are formed by ice crystals falling through the atmosphere.
The wind blows these sideways, giving the distinctive hook shape.
This shot was taken just before dawn near Poolewe in Wester Ross, Scotland.
