Met Éireann rain fall weather chart

Met Éireann expects that that amount of rain that could fall over Ireland this week could be up three times above normal for this time of year.

With flash and spot flooding already occurring in parts over the weekend, the forecaster says more rain is on the way with more flooding.

"Rainfall details are uncertain, but it is likely to be wetter than normal for most of the country with current indications suggesting amounts between 145 and 300 % of the norm over the 7-day period, with the wettest conditions over Munster," said the Met Éireann farming forecast issued on Sunday, September 22.

The summary national outlook is that low pressure will dominate the weather pattern through the coming week, bringing unsettled weather overall. MORE DETAILS BELOW TWEET
