The State's Crisis Management Team is asking people in areas affected by Storm Betty to stay safe and be prepared.
Weather alerts have been issued for the entire country as the storm heads for Ireland.
Yellow and Orange warnings for rain and wind, as well as a Red marine warning off the south coast, are in place.
The National Directorate for Fire and Emergency Management (NDFEM) said it has been liaising with Met Éireann.
A briefing was held earlier with all local authority severe weather assessment teams, Government departments and agencies to prepare for the arrival of Storm Betty.
Current forecasts indicate the storm will move across the country during Friday afternoon into Saturday morning, moving southwest to northeast.
It will potentially bring strong winds, rain and the threat of coastal flooding.
Storm Betty is forecast to bring high winds, particularly across southern areas, with rainfall levels of 40mm across the country.
There is potential for over 60mm of rain in some areas.
A number of key public safety and information messages have been issued by the NDFEM.
In areas affected it is likely there will be:
- High seas: The public is advised to stay away from coastal areas during this period
- Very strong winds: These will make driving conditions hazardous, especially for the more vulnerable road users, e.g. cyclists, pedestrians, motorcyclists and high-sided vehicles
- Road users should pay particular attention to the risk posed by fallen trees and flying debris as trees are in full leaf
- Potential for tidal flooding in coastal areas: Especially in southern and eastern counties
- The storm may also bring localised heavy showers, which in turn may lead to surface flooding in urban locations
