Snow and icy surfaces leading to difficult travel conditions Monday afternoon, evening and overnight into Tuesday morning.
Outbreaks of rain will arrive from the west during Monday afternoon, turning to sleet and perhaps wet snow at times during the afternoon, evening and first part of the night. Snow is expected on high ground above 200 to 300 metres, where several cm snowfall is likely, and perhaps 5 to 10 cm across the higher parts of the Sperrins and Mournes.
Settling snow looks unlikely on low ground. However, as skies clear overnight, temperatures will fall widely below freezing with ice forming on untreated surfaces. This will lead to difficult travelling conditions.

Regions and local authorities affected:
- County Antrim
- County Armagh
- County Down
- County Fermanagh
- County Londonderry
- County Tyrone
What should I expect?
- Some roads and railways likely to be affected with longer journey times by road, bus and train services
- Probably some icy patches on some untreated roads, pavements and cycle paths
- Some injuries from slips and falls on icy surfaces
What should I do?
Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal. Not needing to rush, reduces your risk of accidents, slips, and falls.
If you need to make a journey on foot, try to use pavements along main roads which are likely to be less slippery. Similarly, if cycling, try and stick to main roads which are more likely to have been treated.
Snowy, wintry weather can cause delays and make driving conditions dangerous. Keep yourself and others safe by planning your route, giving yourself extra time for your journey. Check for road closures or delays to public transport and amend plans if necessary.
If driving, make sure you have some essentials in your car in the event of any delays (e.g., warm clothing, food, water, a blanket, a torch, ice scraper/de icer, a warning triangle, high visibility vest and an in-car phone charger).
Why is the warning yellow?
This warning has a medium likelihood and a low.
