Gale force winds of up to 80mph are expected to sweep Northern Ireland as the latest deep area of low pressure moves in from the Atlantic.
Severe weather warnings of high winds and heavy rain have been issued for today and tomorrow and forecasters warn that a combination of large waves and high tides could cause flooding in coastal areas.
The Met Office warned of the potential for disruption due to the combination of high winds and rainfall of 10mm to 20mm in some places.
A spokesman said: "A very deep area of low pressure developing in the Atlantic on Monday will approach the UK later on Tuesday, spreading very strong winds and heavy rain into southwestern areas, then northwards into parts of Northern Ireland during the evening.
"Another very deep area of low pressure will swing bands of rain and strong winds across the entire country on Wednesday, with impacts focused in southern and western areas."
Last night forecaster Laura Caldwell of MeteoGroup added: "Tomorrow should be nice and dry and there should be some sunshine around with the odd shower. Winds won't be too bad but towards tomorrow evening there will be heavy rain.
"Overnight on Tuesday is looking to be unsettled with strong winds and showers or longer spells of rain."
Winds will be up to 40mph, with certain areas, such as eastern coasts, getting gusts of up to 60mph, she said.
A number of roads across the province were closed yesterday because of fallen trees. The Carrickrovaddy Road in Belleeks, south Armagh, was closed because of trees posing a danger to overhead lines.
Meanwhile, the A2 South Promenade in Newcastle was closed to traffic as high waves overtopped the sea wall at high tide, flooding the road.
The A2 Rostrevor Road at Warrenpoint also closed for a time because of flooding.
The Strangford Lough Ferry Service was suspended temporarily because of high tides.
The Met Office warned people to plan ahead for possible travel delays or disruption of day to day activities ahead of the arrival of more severe weather.
Will Lang, Met Office chief meteorologist, said: "We have more Atlantic depressions heading our way this week."
Will Stephens, RNLI coastal safety staff officer, said: "With more stormy weather forecast, we're asking people to take extra care if they're going down to the coast. Rough seas and extreme weather might look exciting, but getting too close can be risky.
"So respect the water and, in particular, avoid exposed places where big waves could sweep you off your feet."
