The Met Office warning between 4am and 6pm tomorrow, states: “Clearly there is the potential for some severe disruption, and the public are advised to watch for updates to this warning and to be prepared to alter travel plans.”

The Met Office said that the band of snow will slowly weaken through Saturday, with further accumulations over central and and eastern areas of around 5cm in places. During the evening, ice will form in many areas where there is snow cover, lasting into Sunday morning. The warning adds: “The public are advised to be aware of the continued risk of disruption to transport during this spell of wintry weather.”

Sunday is set to be cloudy and light snow has also been predicted during the day on Monday. 

Warwickshire Fire and Rescue Service is warning people about the dangers of frozen ponds,lakes and canals as the freezing weather sets in. In the last two years firefighters have received over 30 calls to ice-related incidents, some of which involved dog-owners falling through the ice trying to save their pets.

People in South Warwickshire are being offered advice on staying safe, warm and well. Dr John Linnane, director of public health at NHS Warwickshire, said: “During a cold spell, when temperatures fall for more than a couple of days, the very young, older people and those with long term conditions can be at a higher risk of developing serious illnesses. In particular, it can make heart and respiratory problems worse and, in extreme cases, can lead to heart attacks and strokes. Residents can take practical steps now to make sure they look after themselves if the weather turns more severe. You can prepare by: making sure your medicine cabinet is well stocked and medicines in date stay safe in the snow. Keep emergency numbers to hand; such as NHS Direct 0845 46 47. If you do need to go outside remember to wrap up warm, black ice might not be visible so wear footwear with good grips.”

 Dr Jane Moore, director of public health at NHS Coventry, said: “It’s important to look after yourself in cold weather and look out for friends, family and neighbours. Avoid going out in icy conditions and be aware of others in the community who may need help if they are unable to get out during the bad weather. Check local weather forecasts for the latest information on weather conditions and staying safe when travelling and venturing outdoors. If you have elderly or disabled neighbours, you can help by just popping round to check everything is okay and the property is well heated."
