Coastal areas will likely be the worst affected.
As the worst of Storm Emma and the Beast From The East has passed up by, that snowfall is turning to rain over the next days.
That will lead to the current build-up of snow across the country to melt, which will in turn lead to flooding.

Gerard O'Flynn of the Irish Coast Guard told

Additionally, the freezing rain will lead to a lot more black ice forming on roads, and drivers are warned not to take on an unnecessary journeys.
