Yellow Weather Warning of Fog for Northern Ireland
The Met Office has issued a Yellow Weather Warning of Fog in certain parts of Northern Ireland.
Not everywhere will see fog, but where it does form, visibility could be less than 100 metres in places.
The fog will slowly thin through mid morning and should clear by late morning.
Areas most likely to be affected are County Armagh, County Fermanagh, County Tyrone, County Down, County Londonderry and County Antrim.
