The Met Office has issued a yellow warning of ice for the Western Isles, valid from 2am until 9am on Saturday (tomorrow).

Icy patches are likely to form overnight leading to a chance of difficult driving conditions on untreated roads or where wet weather has led to wash-off where roads have been treated.

Breaks in cloud cover developing as Friday evening's rain, sleet and snow peters out will allow temperatures to fall and drop below freezing in some places, likely allowing some icy patches to form.
