The Met Office has issued a yellow warning for snow tonight, as the isles continue to be gripped by the winter’s first cold snap.
Sleet and snow showers are expected to hit Shetland, leading to icy stretches on untreated surfaces at lower levels.
People are being asked to be aware of possible disruption to travel early tomorrow morning.
The news has come as council gritters have been treating minor, or “priority three” routes, following Friday’s “freak” driving conditions caused by sheet ice. Back then school children and commuters were delayed, with buses, lorries and even a gritter sliding off the road.
This week the gritters have been out in force on even minor roads, following persistent icy conditions for several days.
