The Met Office has issued a yellow warning for icy patches in Herefordshire and Shropshire.
Icy patches are expected to develop on Wednesday night and Thursday morning on some untreated roads, pavements and cycle paths, as well as where showers continue to fall washing off treatment. Some injuries from slips and falls on icy surfaces are possible.
Herefordshire Council says it will be gritting priority routes from 7pm.
The warning is in place from 4pm today until 11am tomorrow.
