Gritters were being deployed across the north west as darkness approached following a whiteout across region.
A warning has now been issued that temperatures are likely to fall below zero this evening and overnight, which could in turn lead to icy and treacherous conditions on roads and pavements, particularly untreated, non-main routes.
A number of services across the north west were affected by the weather.
Derry City Council decided to close all cemeteries across the city at 2pm as a result of the adverse weather, except for two scheduled funerals.
Refuse collection services were operating as normal where it was deemed safe to do so.
A spokeswoman for Derry City Council said: “The health and safety of staff and the public is our prime concern and drivers of the refuse vehicles are continually assessing each area on approach.
“We would urge the public to be patient to make allowances for the weather conditions and to assist where they can in making all collection points as accessible as possible. Every effort is being made to empty all bins as soon as possible.”
All public parks remained open yesterday afternoon, but local people were advised to “exercise extreme caution as the footpaths are slippy”.
The 3G pitch at Bishop’s Field meanwhile was closed for the day due to the weather conditions.
The team at the TrafficWatch Northern Ireland Winter Service have issued a warning on Tuesday afternoon:
“Temperatures are forecast to fall below freezing and there is a risk of ice on roads.
“The salting of roads on the scheduled network considered to be at risk is planned for this evening.
“Motorists are advised to exercise caution when travelling, particularly when driving on untreated roads.”
