Two counties in particular are most at risk.
Met Éireann have issued an official weather warning for Monday, as their prediction of "high intensity rainfall", with the remnants of Storm Helene threatening to result in flooding in certain parts of the country.
The
Yellow Weather rainfall warning has been issued for Galway and Mayo, and will remain in place from 12pm on Monday, until midnight that night:
"On Monday between midday and midnight 25 to 40 mm of rainfall are expected over west Galway and Co. Mayo with a risk of flooding in places."
Meanwhile, the
Midlands Weather Channel have expanded their warning to Wexford, Waterford, Wicklow, and Dublin, saying the following:
"Details are becoming increasingly clear as to the potential track and intensity of ex-tropical storm Helene as it makes its way across Ireland over the coming 36 hours.
"The strongest of the winds are likely to occur across the south and east coasts, where wind speeds could gust to in excess of 120kph. Further inland maximum gusts could reach as high as 100-110 kph for a time on Monday night.
"Heavy and at times intense rainfall is also likely from storm Helene, with some localised flooding likely in places. All areas are at risk of seeing some torrential rain associated with this storm."
