Alan O'Reilly of Carlow Weather told The Hard Shoulder that while Cork is likely to get the worst weather, many other parts of the country will also see wet and windy conditions.
He said: "We have a storm that's developing very quickly just off the south-west coast... that's going to track into the south-west around midnight tonight.
"The orange warning comes into effect at 9pm, and shortly after that strong winds will start.
"There is a yellow warning for many other areas, including all of Leinster, Clare, Kerry, Limerick, Tipperary and Waterford. It's going to be a very rough night right across the country."
He said the weather system is going to bring gusts and very strong winds into Cork.
High tide is expected at around 6am tomorrow morning in Cork City, as well as a storm surge and potentially up to 20mm of rain overnight.
Alan noted there is a risk of flooding along the south and south-west coast of the country, while the bad weather is expected to continue into tomorrow morning.
He explained: "Cork will see two belts of the wind - the first strong winds early tonight, from around 10-11pm for a couple of hours... but there'll be more strong winds around the time of high tide, around 5-6am.
"The winds will slowly ease then across the country, and it will be after lunch before the east coast starts to see any respite."
He added there will be very heavy rain overnight, and again in the morning with some 'thundery showers' possible.
