Met Eireann has upgraded Storm Darragh to a Status Red warning on Friday night as extremely powerful winds are expected.
The Status Red wind warning for Galway and Clare will be in effect from 10pm tonight until 2am on Saturday morning.
Extremely powerful northwest winds are expected to hit the west coast during this time, causing fallen trees, damage to power lines and some structures, wave overtopping, and very dangerous travelling conditions.
Storm Darragh will bring wet and very windy or stormy conditions tonight. Winds will turn northwesterly and will become very strong, with severe and damaging gusts, and storm force winds on Atlantic coasts.
There will be widespread rain at first, heavy at times and possibly causing localised flooding. The rain will gradually clear eastwards through the night and will be followed by frequent showers.
Storm Darragh will continue to bring very windy or stormy conditions on Saturday morning, with very strong northwesterly winds and severe and damaging gusts.
The Strongest winds will be in the morning but it will stay windy and gusty throughout the day.
Similar Status Red warnings have been issued for Mayo, Sligo, Leitrim, and Donegal.
In Galway a Status Orange wind warning will also be in place from 8pm Friday night until 10am on Saturday morning, with a Yellow rain warning this evening also.
