As Storm Lorenzo approaches Ireland, counties along the West and Southern coasts will be the worst affected.
The effects of Storm Lorenzo will begin to be felt across Ireland from midday tomorrow, peaking tomorrow night and easing Friday morning - it's expected to be a powerful storm, bringing heavy rain, strong winds and high seas.
Met Eireann has issued a status orange wind warning for counties Mayo, Galway, Clare Cork, Kerry and Limerick.
The orange warning comes into effect from 6pm tomorrow evening until 3am Friday morning, with gusts of up to 130 km/hour - higher in coastal regions.
Met Eireann says the storm surges will produce coastal floods and damage.
A less severe yellow wind warning and a yellow rain warning has been issued for the entire country, from 9am tomorrow morning until 6am on Friday morning.
Mayo's Road Safety Office is urging motorists to slow down when the storm hits, as high winds are likely to cause debris on already-wet roads.
Householders are urged to store away garden furniture, trampolines and wheelie bins ahead of the high winds, and people are also asked to check on elderly neighbours during the storm.
The National Emergency Co-Ordination Group has been meeting again this morning to discuss nationwide preparations for the expected arrival of Storm Lorenzo tomorrow.
