How the country fared and what to expect
Louth County Council has advised motorists to avoid any journeys that aren't strictly necessary. Snow hit Monaghan and Cavan yesterday.
The capital was largely unscathed from the snow and ice but is expected to be affected today. Transport services were operating as scheduled.
It was a bright and sunny day in Carlow, Kilkenny and Wexford with no sign of snow. Waterford was hit yesterday afternoon, and the Sally Gap in Wicklow was dangerous. Local authorities are depositing grit to 70 locations across Carlow and Kilkenny for farmers.
Heavy snowfalls and black ice left roads in parts of north and west Cork in a treacherous condition. Temperatures were last night expected to drop to as low as -6C.
Commuters awoke to a thick coating of frost on all roads but there were no major transport problems. Most of Clare, Limerick and north Tipperary enjoyed bright sunshine.
Persistent snow showers swept across Mayo yesterday resulting in schools being closed. Traders in Castlebar, Ballina, Westport, Ballinrobe and Claremorris reported meagre takings. The M6 Galway-Dublin motorway was reduced to a single lane from Ballinasloe.
Traffic chaos descended on the north-west as heavy snowfalls and icy conditions led to tailbacks. Soldiers at Finner Camp were deployed at lunchtime to clear paths at a number of schools in the Bundoran area of Co Donegal. Local authorities in Sligo deployed snow ploughs to keep the roads clear.
