The Met Office has issued a yellow warning for ice in south London tomorrow which could cause travel disruption.
The warning is in place between 3am and 2pm (December 18).
The Met Office warns of some risk of injuries from slips and falls on icy surfaces, icy patches on some untreated roads, pavements and cycle paths and potential travel disruption.
A level three cold weather alert was earlier issued by the UK Health Security Agency (UKHSA) for all of England until midnight on Sunday, which it warns could “increase the health risks to vulnerable patients and disrupt the delivery of services”.
Forecasters say temperatures could temporarily rise on Sunday but this will bring strong winds leading to snow, blizzards and ice and freezing rain, creating hazardous conditions on the roads.
Today the forecast for London and south east England reads: “Frost and freezing fog patches slowly lifting as a gentle breeze develops. Then dry with bright or sunny spells.
“The highest temperatures will be along the south coast and for the Isle of Wight, where isolated showers will also arrive. Maximum temperature 7 °C.”
Tonight you can expect “Dry with clear periods, with temperatures quickly falling inland allowing a widespread moderate frost to develop and perhaps isolated freezing fog patches.
“Milder along the south coast with onshore winds. Minimum temperature -6 °C.”
Tomorrow’s forecast reads: “Any early freezing fog patches soon clear as cloud increases. Then becoming windy as occasionally heavy rain, possibly preceded by temporary sleet or snow, spreads east. Maximum temperature 8 °C.”
