Storm Jocelyn will batter the west coast on Tuesday evening, bringing very strong southwest to west winds with severe and damaging gusts.
A status orange warning has been issued for Galway, Mayo and Donegal ahead of the storm, which will arrive less than 48 hours after Storm Isha caused significant damage and disruptions across the West on Sunday night.
The potential impacts of Storm Jocelyn include large coastal waves with wave overtopping, very difficult travelling conditions, fallen trees, damage to power lines, and damage to already weakened structures.
The weather warning will come into effect at 6pm on Tuesday, remaining in place until midnight in Galway and Mayo, and until 2am on Wednesday in Donegal.
The rest of the country will be under a status yellow warning until the storm subsides.
