The body which represents the insurance sector has said indications from its members are that the total cost of claims for Storm Éowyn could grow to as high as €300 million.
This would make it the most expensive weather event in the State in the past 25 years.
Figures published by Insurance Ireland from its members put the estimated costs of claims for the Storm Éowyn - so far - at more than €197m.
The organisation said situation is still ongoing and members continue to receive, assess and settle claims so the figures are not final.
Insurance Ireland had estimated a cost impact of between €150m to €200m.
However, in a statement they said that given that they are already approaching the upper limit of that estimate, it will likely be surpassed by quite a margin.
They said indications they have received from members is that it could grow to €300 million.
At the height of Storm Éowyn 768,000 homes, farm and business were without electricity, according to ESB Networks.
Uisce Éireann reported that almost 140,000 homes were without water after the storm hit.
Around 160,000 homes and business lost broadband access due to outages caused by Storm Éowyn, according to Eir.
To date the largest insurance cost for previous weather events was €297 million in January 2010 due to freezing weather conditions.
