The Church of Ireland has launched a Flood Relief Appeal to offset what it calls the "extensive hardship" being experienced in many places across the island.
In a statement, the Church's hierarchy said people have been left without food, shelter, warmth and clothing as a result of flooding and water damage.
They appealed for contributions to a fund which will provide small grants to help those with immediate needs.
The archbishops and bishops asked Church members to respond generously to their appeal and say monies will be administered with the help of Protestant Aid, a charity with extensive experience in providing welfare assistance.
They also say that, where appropriate, parishes or other local agencies and charities will administer the monies.
Applications for assistance can be made to rectors or, in the case of parish vacancies, to rural deans or diocesan offices.
Individual donations may be made online or by cheque.
The bishops say parishes may also organise special collections at Sunday services over the next two weeks.
The flooding situation has not escalated in the past 24 hours and the national emergency coordination group said they are encouraged by the signs.
However, the recovery phase from the flooding will continue for some time.
The flooding situation remains severe in the mid and lower sections of the River Shannon with many people still affected.
The level of the Shannon in Athlone is now back to the maximum level recorded in 2009, according to Westmeath County Council.
It expects that trend to continue but said the rate of decline in the level of the river will be very slow at about 2cm per day.
Gardaí, Irish Water, the Defence Forces, Civil Defence, the HSE and the council met this morning as part of the Flood Response Interagency Group.
Transport services to flooded rural areas to the south of Athlone are to continue.
The service is available to bring children to school and to bring other residents to Athlone.
