Louth is one of the counties most likely to be flooded.
A new study has found both Louth and Clare scored highest because they're at risk of both coastal and river flooding.
Gamma, a location intelligence solutions company, also found Longford is the county least likely to be affected by flooding.
The study found 60,000 homes across the country are at risk of flood damage.
Nine percent of homes in Louth faced potential flooding while only one percent of houses in Longford had the same risk.
The Sun report that Cavan and Westmeath also had a low percentage of homes in high flood risk zones, at about one per cent and two per cent respectively.
The findings were determined using a detailed 3D-flood model which assesses the risk by considering both the source of the flood as well as likely water depth.
