The Met Office have warned Wirral to expect snow and Ice through Thursday and into Friday.
Some injuries due to trips and falls and travel disruption could be expected in areas with untreated surfaces.
Temperatures are expected to remain at just 2C throughout the whole of Friday, with the greatest chance of snow at around 2pm.
A forecaster at the Met Office said: “Showers, a mixture of rain sleet and snow, are expected to fall onto frozen surfaces leading to icy stretches forming.
“In addition, a more persistent spell of rain and hill snow is likely to spread south across northern England and north Wales during Thursday evening and night.
“Whilst ice is expected to be the main hazard, snow is likely in place too. Snow is most likely to fall over The Pennines, North York Moors and the high ground of Wales, with 1-3 cm possible here.
“Elsewhere, whilst some snowfall is possible, accumulations are likely to be slight and temporary.”
Ice formed overnight during the early hours of Thurday when temperatures dropped to -2C on Wirral.
