Met Eireann has forecast a big weather change, with freezing temperatures and ice to give way to strong winds and heavy winds.
A Status Yellow weather warning for all of Ireland is in place until 11am, with people told to be on alert for patches of ‘freezing fog’.
Freezing fog is considered rare because specific circumstances are required for the fog to form. The fog consists of ‘supercooled’ water droplets, which means the moisture remains liquid despite temperatures being below freezing.
