A Status yellow snow and ice warning for Ireland remains in place until 10 o'clock this morning, with slippery road conditions reported in many areas of the West.
The snow and ice follows on from the strong winds and heavy rainfall over the weekend.
Storm Ciara continued into the early part of this week, and severe gusts yesterday morning ripped the entire flat roof from Dooagh National School on Achill Island.
The incident occurred at about 9.30 am yesterday morning.
Principal Irene Gielty told Midwest News that there was a constant gale in the area yesterday morning with severe gusts.
Shortly before 9.30am, a violent gust hit the school and ripped the entire flat roof, an area of 200 square metres, and landed it in the adjacent football field.
Ms Gielty says the whole roof was airborne, and some parents witnessed the event and described it as similar to a scene from a disaster movie.
The Principal said no-one was hurt, but she questioned what the criteria is for a red wind warning , given that a status yellow wind warning was in place in Mayo yesterday.
Meanwhile, Ireland is braced for Storm Dennis this weekend.
Met Eireann is urging the public to stay tuned for weather warning updates, after the UK Met Office advised Storm Dennis could pose "a danger to life".
The storm is due to arrive on Saturday, bringing very wet and windy weather for the weekend.
