The Met Office has issued an orange alert – its second highest – for a storm system approaching the Mayo coast from the Atlantic. The weekend will also feature very high tides combined with unusually high waves.
The Met Office warning says: An Atlantic storm depression will track to the northwest of the country later Friday night and Saturday.
Southwest winds gusting 100 to 130 km/h, strongest across the Atlantic counties.
Frequent heavy showers, some thundery with sleet and snow for a time mainly on higher ground.
High coastal flood risk too due to the combination of very high spring tides, extremely high waves (greater than 10 m), low pressure and onshore winds – southwest, west and northwest margins most at threat.
