Local authorities are to establish emergency response hubs in the areas that are most impacted by power outages caused by Storm Éowyn.
The National Emergency Co-ordination Group (NECG) said that these hubs will support people with "basic needs such as water, hot food, phone charging, broadband access, shower and clothes washing facilities".
Local authorities will also continue to manage local coordination groups in order to coordinate available supports and assistance, including the Department of Social Protection's Humanitarian Assistance Scheme.
However, it is anticipated that not all local authorities will set up emergency response hubs or local coordination groups as they "gauge the level of response required in their areas".

Repair crews are continuing restoration works to restore electricity, with engineers from the UK coming over to assist ESB Networks.
Power has been restored to 438,000 customers but around 330,000 homes, farms and businesses remain without supply.
ESB Networks said it could be Friday before supply is restored for most people.
However, it added that as many as 100,000 customers could still be without power next week also.
It also urged people not to approach or touch downed power lines and said it has been made aware of "potentially very dangerous incidents" where members of the public have unknowingly approached fallen electricity infrastructure.
It advised anyone who comes across fallen wires or damaged infrastructure to call 1800 372 999.
The NECG also said that Ireland has "activated the EU Civil Protection Mechanism" and requested "high -capacity generators to support critical infrastructure operators" while power supplies are restored.
Chair of the NECG Keith Leonard again urged road users to take extra precautions amid the clean-up operation.
Meanwhile, several Status Yellow weather warnings were in effect as damage from Storm Éowyn continued to be assessed.
Met Éireann warned of heavy downpours of rain that may lead to spot flooding. A Status Yellow rain warning for Carlow, Kilkenny, Waterford, Wicklow, Cork, Kerry and Tipperary expired at 5pm yesterday.
Uisce Éireann said that more than 109,000 people were without water and warned that supplies for a further 126,000 people were at risk. An additional 112,000 people were being supplied by schemes where generators have been deployed by Uisce Éireann crews.
The worst affected areas were Galway, Mayo, Clare, Cavan, Monaghan, Westmeath, Donegal and Longford.
Head of Water Operations at Uisce Éireann Margaret Attridge noted that while positive progress had been made, the number of people experiencing loss of supply due to power outages remained significant.

"This unprecedented storm event has had a severe impact on our water and wastewater network nationwide," she said.
Eir said that broadband services have been restored to 110,000 homes and businesses since Storm Éowyn hit Ireland on Friday.
However, it also estimates that there are still 94,000 customers without broadband.
A spokesperson said: "Service restoration for core and mobile networks will remain a priority.
"It is expected that there will be a significant number of individual faults in addition to this, but the full impact of these will only become clear after power is restored and after resolution teams have prioritised making fallen poles and lines safe."
Met Éireann said damage to already weakened structures and hazardous travelling conditions can also be expected in Carlow, Dublin, Kilkenny, Wexford, Wicklow and Galway as a Yellow wind warning expired at 3pm.
A Yellow wind warning for Donegal, Leitrim, Sligo, Louth and Meath expired at 6pm.
An additional Yellow wind warning was issued for Waterford, Cork and Kerry from 11pm yesterday until 9am this morning.
A Status Yellow warning for snow and ice for Donegal, Leitrim, Mayo and Sligo expired at 9am, while a Status Yellow wind warning for Munster expired at midday.
Storm Éowyn brought record-breaking gusts of 183km/h, and the damage is still being assessed around the country.
