Met Éireann has issued three weather warnings, including a status red rainfall warning for Connacht, Donegal, Clare and Kerry
The National Co-ordination Group for Severe Weather Emergencies will meet this afternoon after Met Eireann upgraded its weather warning to the highest level as Storm Desmond prepares to hit.
Further poor conditions are forecast for the next 48 hours, with extended periods of torrential rain expected for the northwest and west. It is forecast that Saturday will be an "exceptionally wet and windy day" for most parts of the country.
