The environment minister is expected to seek an additional €10m in funding
A new body is to be set up to coordinate the response to future flooding along the River Shannon.
The setup of a Flood Management Coordination and Implementation Group is among the matters being discussed at a crisis summit at Government Buildings this afternoon.
The new group would coordinate the local flood management plans for 66 different towns and settlements along the Shannon which are vulnerable to flooding.
Junior Minister Simon Harris says other measures being discussed today include funding for a long-term weather forecasting system.
"There's no point having committees and groups if you don't actually have the information that we require, and we don't have a national flood forecasting system in this country, that's why we need to develop one" he said.
"This will enable the State, it will will enable communities, it will will enable local authorities - and all bodies that have a role in the Shannon - to have the right information available so that they can make strategically important decisions to protect communities, homes and livelihoods along the River Shannon" he added.
It comes as flood waters in the River Shannon have now reached peak 2009 levels, Offaly Council Council has confirmed.

Council officials say electricity has been cut off to part of Shannon harbour, while it remains off in parts of Portavola Estate in Banagher.
