Orange and amber wind warnings remain in place in 11 counties on the island.
A Met Eireann orange alert for Kerry, Leitrim, Sligo, Clare, Donegal, Mayo and Galway came into effect at 10am on Sunday and will be in place to 8pm.
The forecaster said the first named storm of the season is to bring very strong and gusty south to south-west winds, coupled with high spring tides. The counties covered could see gusts of up to 130kph.
The forecaster said there was the possibility of coastal flooding, large coastal waves, displacement of loose objects, fallen trees, very difficult travelling conditions, dangerous conditions at sea, as well as damage to power lines and already weakened structures.
In Northern Ireland, a Met Office amber alert for counties Antrim, Fermanagh, Tyrone and Londonderry is in place from 1pm to 8pm.
The UK forecaster said the storm would bring a spell of strong winds, causing some disruption.
The rest of the island is covered by a yellow wind warning.
In the Republic of Ireland, that warning came into effect at midnight on Sunday morning and will remain in place until midnight on Monday morning.
In Northern Ireland, the yellow wind warning lifts just before midnight on Sunday night.
The National Directorate for Fire and Emergency Management (NDFEM), Met Eireann and various other stakeholders in Ireland are involved in planned for the storm.
Local authority severe weather assessment teams (Swats) have local emergency response teams in place.

Multi-agency partners in Northern Ireland have also continued to meet over the weekend in preparation for the storm.
As part of the response, temporary tidal flood defences have been deployed as a preventative measure along sections of the River Lagan in Belfast.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
