The warning has been issued for counties Donegal, Galway, Mayo, Clare and Kerry and it is set to be valid for a 24-hour period from 2:00pm today, September 28.
Southerly winds of between 55kph and 65kph are expected to affect Atlantic coastal fringes of the west and north-west, with the danger of gusts reaching 90kph to 100kph.

However a few showers are likely to develop in the west and southwest. Winds will mainly be moderate to fresh and southwest in direction; but they will be staying strong to very strong and gusty along Atlantic coasts.
