Thousands of people in Shetland are facing a fourth day without power as engineers battle to restore supplies amid the threat of further snowfall and freezing temperatures.

Some 2,400 homes remain without power in Voe, Brae, Yell and the West Mainland – with engineers warning that power may not be restored to some properties until the weekend.

Scottish and Southern Electricity Networks (SSEN) Distribution said it was continuing to “battle prolonged severe weather conditions”.

A team of 125 people is carrying out repairs to restore power, with SSEN saying “this remains likely to extend to the end of this week”.

“Depending on weather conditions and travel availability, it is possible this could extend into the weekend for some properties,” it added.

Icy conditions are forecast to continue over the next 24 hours, with frequent rain, sleet, hail and snow showers.

The Met Office has extended a yellow warning for snow and ice covering northern Scotland and north-east England until 11.59pm on Thursday.
