Drivers are being warned to mind themselves on the roads, as Storm Babet hits the country today.
An Orange rainfall warning has been out in place for Waterford, Cork and Kerry until 1pm tomorrow.
However, the rest of country isn't totally safe either. A yellow rain warning has been announced for the rest of Munster, Connacht and Leinster.
Cavan, Donegal, Monaghan, Clare, Limerick, Cork, and Tipperary are said to be particularly affected.
The Road Safety Authority expect flooding and dangerous road conditions. It also predicts that some coastal areas could see wave overtopping.
David Martin of the RSA gave this advice:
"If you have to take the journey just slow down,
allow a great or breaking distance between yourselves and the vehicle in front.
And this is especially important for people who may be travelling in dual carriageways or motorways,
where there's an increased danger of aqua planning."
That warnings end tomorrow evening.
Cathal Nolan of the Ireland's Weather Channel expects the bad weather to be with us all week:
"As we go on into Wednesday and Thursday.
The main focus of that heavy rain then shifts up along the east coast.
So I wouldn't be surprised if that status orange weather warning was maybe extended into parts of
maybe Wicklow and even Dublin itself as we go on into Wednesday and Thursday.
But we could see some further heavy falls of rain, maybe up to 50 or 70 millimeters over higher ground in those locations."
