Storm Ellen is moving over Ireland across Wednesday and into Thursday.
Several weather warnings have been issued for the entire country, including a status red wind warning for Cork.
The storm will track over Ireland on Wednesday night and during Thursday, bringing a period of severe and potentially damaging winds.
Meanwhile the crisis management team of the National Directorate of Fire and Emergency Management (NDFEM) met on Wednesday morning.
The NDFEM also followed up with calls to coastal counties, advising of potential for coastal flooding and very high winds along exposed coasts.
Local authorities are deploying temporary flood defences, and putting response staff on standby.
They will also be providing public safety advice based on local conditions.
The NDFEM has issued a number of key public safety messages:
- This is an exceptional storm for August - people should take account of Met Éireann weather warnings affecting their location
- Many people are on holidays at coastal locations. Stay away from all coastal areas for the duration of the Met Éireann warnings
- All road users should be aware of the hazardous traveling conditions. Motorists should slow down and be aware of the dangers of fallen trees and debris. High sided vehicles are particularly vulnerable during this time
- As conditions will vary people need to take account of the local conditions and advice from their local authority
- It is critical that people never ever touch or approach fallen wires, stay safe and stay clear of fallen or damage electricity wires, and contact the ESB on 1850-372-999

Local authorities have also been advised to actively monitor Met Éireann and OPW forecasts during the unsettled weather.
They should also consider activation of crisis management and local co-ordination arrangements, the NDFEM says.
It also notes that trees are in full leaf, with the potential for significant numbers of trees to fall - blocking roads and damaging power lines.
ESB Networks is preparing for "significant power outages", with staff on standby to repair faults in all areas.
The Irish Coast Guard, An Garda Síochána and local authorities are relaying public safety advice based on the warnings issued by Met Éireann ahead of the storm's arrival.
