A yellow weather warning has been issued for snow and ice across Gloucestershire.
Forecasters at the Met Office said icy stretches are expected to develop this evening, due to ongoing wet surfaces following earlier rain and, in places, snowmelt.
Frequent sleet or snow showers are also expected to affect Wales and parts of northwest England this evening, moving into southwest England, the Midlands and parts of southern England in the early hours of Tuesday.
The warning which covers Gloucestershire will come into force from 5pm today until 10am on Tuesday.
