Storm Hannah is due to hit parts of Britain and Ireland this weekend bringing gale-force winds and heavy rain from the Atlantic Ocean.
The Irish Met Office decided to name the storm as forecasters predicted strong gales in Cork and Kerry on Friday night.
Hannah will also bring winds of up to 75mph and stormy conditions to south west England and southern parts of Wales, with a yellow weather wind warning in place from 9pm on Friday to 3pm on Saturday.
Conditions are expected to have settled down on Sunday, when runners will take to the streets in their thousands for the London marathon.

Yellow weather warnings in place for south west England and Wales could mean power outages, travel disruption and flying debris around coastal areas.
Met Office spokesman Grahame Madge said that the system will affect Ireland the most, but areas around Cardiff, Devon and Cornwall and the south coast will experience disruption.
He said that Met Eireann had chosen to name the storm based on its own criteria and the potential impacts for Ireland.
Mr Madge added that from early Friday winds will start to strengthen, and by the evening rush hour Storm Hannah would start to hit western Wales and parts of Scotland.
He said that going through the evening, the low pressure system would cross into parts of Ireland, affecting western parts.

Bookies are offering 3/1 odds on this month being the wettest April on record, while they have cut odds on UK winds reaching 100mph by the end of the week at 2/1.
Despite the forecasts for storms this week, the odds have been trimmed on next month being the hottest May ever in the UK into 6/4 from 2/1.
‘Storm Hannah is set to deliver us a wet and windy end to the week with some punters backing the speed to reach as high as 100mph in the mainland UK before the weekend is up,’ said Coral’s John Hill.
‘Despite a damp outlook for the rest of the week, the odds indicate next month is going to be glorious as the odds have been cut on us having the hottest May on record in the UK,’ he added.
