Though there is still uncertainty about the exact track of Hurricane Lorenzo, Met Eireann say that it is most likely to hit on Thursday bringing with it severe winds.
They say: "On its current forecast track, it will pass close to the western Azores early on Wednesday, weakening after that to an extra tropical low, with an increasing probability that it will pass close to or over Ireland during Thursday and Thursday night."
There will be spells of torrential rain, high seas and swells with the European Centre for Medium-Range Weather Forecasts predicting winds of over 154km/h for Ireland.
For Tuesday in Dublin, it will be cloudy for a time with patches of rain but it is set to brighten up gradually during the afternoon with sunny spells developing later in the day.
Temperatures will reach highs of 14C in the capital with strong winds to match but that will dip to as low as 1C as the night will be cold with patches of fog and mist.
Met Eireann has two weather warnings in place for Tuesday also, a status yellow gale warning and a status yellow small craft warning.
The status yellow, gale warning means "North to northeast winds will occasionally reach gale force today on Irish coastal waters from Belfast Lough to Howth Head to Carnsore Point and on the Irish Sea".
The status yellow, small craft warning means "Northeasterly winds will reach force 6 or higher today on Irish coasts from Carnsore Point to Slyne Head to Belfast Lough".
In the UK, the Environment Agency has issued 80 flood alerts ahead of today's torrential downpours, which have forced hundreds of people to evacuate.
Flooding is expected in every part of England today, prompting the Met Office to release two yellow weather warnings also.
