Motorists faced another day of weather-related misery on the roads on Friday with many areas of the Province affected by snow and ice.

Saturday night will be significantly colder again with overnight lows of minus 6C across Northern Ireland followed by a day of sleet and snow showers on Sunday.
Neil Megaw, principal of Newtownhamilton High School, Co Armagh, said Friday morning was particularly bleak.
“Over 80 per cent of our pupils come into school by bus but it was evident the bus drivers did not feel they could risk going out.
“No school is able to function when 80 per cent of its pupils are not able to attend. So we put the message out on our website and on Facebook this morning that we would be closed.”
The school has 170 pupils aged from 11 to 16, many of whom he imagined would have spent the day making snowmen and snowballs instead, he said.
Mr Megaw added: “The bus drivers just felt they would not be able to drive on them.”
