Get the fire on: Northern Ireland set to shiver in cold snap
The Met Office has issued a yellow warning for ice across Northern Ireland.
Temperatures are set to plummet on Sunday evening leading into the new week with potentially difficult driving conditions for the Monday morning commute on untreated roads.
Wintry showers, with the possibility of snow, are also set to hit with higher ground getting the worst of it.
The ice warning is in place from 9pm on Sunday until Monday at 9am.
Road temps are forecast to fall below zero tonight. Salting of scheduled roads is planned. Caution advised especially on untreated roads.— Trafficwatch NI (@TrafficwatchNI) February 26, 2017
Forecaster Marco Petagna said the low pressure system will move across the country on Monday and Tuesday, with temperatures of 5C or 6C.
"The first half of the week will be cold and windy, it will start to turn milder for the second half of the week," he added.
The Met Office issued a yellow alert for a "small area of very strong winds" likely to move north-eastwards over parts of the north-western half of the UK.
"The area of strongest winds will arrive over north-west Wales late on Sunday morning and clear the north-east of Scotland on Monday morning," it stated.
Last week Storm Doris caused travel disruption, damaged buildings and sent debris flying.
Tahnie Martin, 29, who worked at the University of Wolverhampton, was killed in Wolverhampton city centre after being struck by flying debris.
The current weather system has been dubbed Storm Ewan in Ireland but conditions are not severe enough in the UK to be categorised as a storm.
Storms with the potential to cause a substantial impact are named by the Met Office and Met Eireann, moving through the alphabet.
The first was named Abigail in November 2015, after members of the public suggested monikers for the "name our storms" project.
Forecasters are now in their second run through the alphabet.
After Ewan, Britons can expect to hear of Fleur and Gabriel.
