Drivers have been advised to leave extra time to prepare their vehicles and to carry essentials such as warm clothing, food, water, a blanket, a torch and a phone charger in case of delays.
Those on foot should use pavements along main roads, which are more likely to have been treated, to reduce the risk of slips and falls.
Cyclists have been advised to stick to main routes for the same reason.
Residents should be prepared for any short power cuts by keeping torches, spare batteries and a mobile pack ready.
The Met Office warned weather warnings can change quickly and recommended people keep up to date with the latest forecasts.
