A yellow warning means some disruption is possible, such as travel delays, but many people can continue with their daily routine, according to the Met Office.
An amber warning indicates a higher risk, with severe weather likely to cause travel disruption, power cuts and the potential risk to life and property and people are advised to take precautions.
Rain, sleet and snow is expected to move in from the north-west on Tuesday as the UK faces “another very cold day”, with as much as 10-15cm of snowfall expected in parts of Scotland and between 1–5 cm likely in areas of England.
