Storm Ciarán was named by the UK Met Office on Sunday, October 29, with Met Éireann forecasting that the storm is due to pass close to the south coast of Ireland on Wednesday night, November 1.
In an advisory for the entire country, Met Éireann says that on Tuesday and Wednesday, there will be heavy showers or longer spells of rain at times with flooding likely in places, as soils are saturated and river levels are high.
Squally showers on Wednesday morning will be accompanied by very gusty conditions.
Later Wednesday and on Thursday, further rainfall associated with Storm Ciarán may lead to flooding. It is likely that the heaviest rain will be in southern and eastern coastal counties.
Met Éireann said additional impacts include poor visibility and difficult/dangerous driving conditions.
Several weather warnings are in place across Ireland and Northern Ireland ahead of Storm Ciarán.
A Status Yellow rain warning is in place for Co Kerry until 12 pm tomorrow, November 1. Met Éireann has warned that rain, with heavy falls at times, could cause localized flooding, difficult travel conditions, and poor visibility.
Met Éireann noted that the UK Met Office has issued a yellow rain warning for Cos Antrim, Armagh, Fermanagh, Tyrone, and Derry, valid from 9 pm on Tuesday through 9 am on Wednesday.
