The hurricane has already been reduced to a tropical storm as it loses energy while travelling over the cold waters of the Atlantic.
The former category two hurricane is going to be absorbed by low pressure and weakened as it makes its way across the Atlantic towards the United Kingdom leaving a gap in the weather system for humid air to sneak upwards from the south.
Monday could be the hottest day of the year if temperatures hit 26C or 27C on Monday, Met Office said.
Met Éireann also has a Status Yellow warning in place for Donegal, Galway, Leitrim and Sligo which ends at 4pm tomorrow.
With heavy rain overnight on Sunday and into this Monday morning leading to spot flooding, the forecast is for more of the same.
Continuing changeable and unsettled weather is expected up until Monday.
Today, Thursday, there will be a mix of cloudy and sunny spells.
There will be a risk of low visibility in coastal and hill areas due to patches of rain, drizzle and fog.
"Some heavy, possibly thundery bursts will occur locally, especially over parts of Connacht and Ulster" are forecast for tonight.
Temperatures in those regions will likely remain around 18C to 19C on Sunday, while higher ground in parts of western Scotland and north-western England could see up to 25mm of rain - or a third of a month's rainfall - in a few hours. Farmers should aim to graze their drier paddocks first - focusing on these paddocks will allow you to make the best use of your grass and keep poaching to a minimum.
