In pictures: Strange clouds that followed Storm Amy

Last weekend's Storm Amy caused power cuts, brought down trees and damaged sub-sea internet cables to Shetland and Tiree.

In the wake of the storm, unusual clouds were spotted from parts of Scotland.

BBC Weather Watchers captured some of the scenes on Monday.

Striking asperitas formations were among the clouds spotted.

The Met Office describes them as a new and rare cloud type that look like "rippling ocean waves in the sky".

It also said why these clouds form remains a mystery, but it is thought their appearance is associated with thunderstorms.

The Met Office added: "What is clear, however, is that atmospheric conditions must be unstable to form a wavy cloud base like that seen with asperitas."

BBC Weather Watcher Martainn pictured asperitas from Arnisdale, in the west Highlands, on Monday evening.

Similar formations were seen from Lochcarron, also in the Highlands.

In parts of north east Scotland, there were double rainbows and some dramatic sunsets.
