Homes in Shetland and surrounding areas have been affected by a power cut amid “heavy snowfall” and freezing temperatures.
The cut was first reported shortly before 3pm, with power expected to be restored by 9pm.
Police on the island have urged people to avoid travelling “unless absolutely necessary”.
Anyone who needs to should allow for extra time, take warm clothes, food and water in case of delays, and fully charge their mobile phone, they said.
Shetland Police warned that some residents in the Burravoe and Bressay areas may not be able to make outgoing calls – including dialling 999 – from their landline, however mobile phones remain unaffected.
