Local people have been urged to brace themselves for Arctic winds, and the return of sub-zero nights and wintry showers later this week.
Met Eireann in the south is predicting that widespread rain on Tuesday night will be followed by a cold blustery showery day on Wednesday, with some of the showers turning wintry especially in the North and West.
A spokesman said: “For Wednesday night and the rest of the week it will be bitterly cold as a strong and blustery Northwest airflow becomes established over the country.
“It will be windy with frequent wintry showers giving falls of sleet and snow and accumulations of several cms of snow are likely in many areas, particularly in the North and West.”
The Met Office in the north meanwhile have said that a warning is now in force from 9am on Wednesday right through to 11.55pm on Thursday, amid predictions that in some parts of the north, 5 to 10cm of snow is likely, even at low levels.
