Evening bus services to and from Stornoway tonight have been cancelled, Comhairle nan Eilean Siar has announced

A statement said: "Due to the risk of ice and snow and freezing temperatures all evening, bus services to and from Stornoway after 7pm on Tuesday 16th January 2018 are cancelled.

"All other earlier bus services are expected to operate but may be subject to disruption or cancellation at short notice.

"Passengers are advised to contact bus operators directly using the contact phone numbers within the current public bus timetables.

"Timetables are available on the Comhairle website."

The public are advised to travel only if necessary.

The Met Office forecast says: "Heavy, squally showers of snow will continue through Tuesday and Tuesday night, although perhaps more of sleet and hail near some coasts.

Over the hills, snow will drift in the strong to gale force winds.

There is likely to be an increase in snowfall amounts this evening, especially for parts of southern Scotland and Northern Ireland for which a separate Amber warning will be in force. A gradual improvement is likely on Wednesday for most areas.

Travel delays on roads are possible, as are public transport cancellations. There is a chance of power cuts, while services such as mobile phone coverage may be affected. A few rural communities may become cut off.

In addition some roads and pavements will turn icy, increasing the chances of accidents or injuries.
