Crane shakes in Gertrude's wake
Time-lapse footage shows a crane being shaken by Storm Gertrude on Friday morning.
Tom Mortimer watched the scene from Edinburgh's Royal School of Veterinary Studies.
Schools have been closed, train and ferry services disrupted, bridges shut and more than 8,000 homes were left without power due to the strong winds.
Weather forecasters have issued a red "take action" warning, which means potential for danger to life, for wind in Shetland on Friday afternoon.
