South Wales and Cornwall are expected to bear the brunt of the remnants of Hurricane Helene, which is now off the Azores.
They explained: "Very windy across Ireland from early on Wednesday morning until evening".
The warning will affect five counties: Galway, Mayo, Sligo, Leitrim and Donegal and will be active from 1pm on Monday until 5am on Tuesday.
He said: "[Helene] is an intense area of low pressure, heading up towards the United Kingdom, bringing some tropical weather with it."It is a few days away, but we do have weather warnings in force.
Looking ahead to the forecast for the upcoming days, Met Eireann say there will be scattered outbreaks of rain and drizzle today, sometimes heavy in parts of Connacht and west Ulster.
"A spell of strong winds is expected, initially mainly in the far southwest of England and across western Wales".
In an update on Sunday evening, the Met Office spokesman said: "There is not a danger to life, but we are just saying be prepared for it be very windy for a while".
"The timing and development of both these systems remains uncertain, however, so please keep up to date with the warnings and forecasts".
"Another storm could arrive Thursday night into Friday but the track is uncertain and it may miss us and head for the United Kingdom".
The majority of Helene's strong winds had been predicted to spend themselves over the Irish Sea from Monday night and into Tuesday morning but winds are now set to continue into Wednesday.
"There is a lot of uncertainty around the development of that low-pressure system".
Warm and humid air from the continent, combined with a tropical flow from the remnants of Helene, should lift temperatures between 21 to 24C in southern regions but into the mid to high teens C across the north.
Leading bookmaker Coral has seen a flurry of bets on this month ending as the wettest September on record in the UK.
Helene was downgraded from a Category 2 hurricane to a tropical storm Thursday.
