More severe weather is likely tonight, with temperatures in areas around Melksham to reach -7C, carrying on into the weekend, with freezing ice conditions as road temperatures drop. This will lead to hazardous driving conditions on roads and pavements, especially off the main roads where they may not have been salted.

So, the police are offering the following advice:

* Only to travel if it is essential.

• If you have to travel, be very careful on the roads. Drive appropriately to the weather conditions.

• Help keep traffic levels down to help the emergency services keep moving.

• Only call 999 in a REAL emergency.

• If you are travelling on public transport, check that the service is running before setting out. Use websites for information updates.

• Look out for your neighbours, especially older people and those with disabilities.

(The police also recommenr that you only throw snowballs responsibly. Yes, really!)
