The Met Office has issued a national severe weather warning which is expected to mean gale force winds and heavy rain across Northern Ireland tomorrow.
The Yellow warning requires public awareness of the issue, with gusts of up to 60mph and 20mm of rain possible.
“Today will not be a bad day, very breezy with sunny spells with a few showers in the west,” a spokesman for forecaster Meteogroup said. “It will be cloudy and wet overnight and fairly windy.”
But Friday will see wet and windy conditions likely across Northern Ireland and a risk of snow above about 300m early in the morning.
The Met Office warned the public to be aware of the risk of flooding on roads and rivers.
A developing Atlantic low pressure system will push heavy rain across Northern Ireland with more than 20mm expected widely.
With ground already saturated due to heavy rain yesterday, this could lead to further flooding.
The Met Office said strong to gale force southwesterly winds are expected.
The forecaster also warned that tides will be very high, and the public should be aware of the risks of large waves and coastal flooding.
Winds will gust to around 50-60mph over coasts and hills.
Whilst this is not especially strong, lowering pressure will combine with high tides around the UK coastline and bring the risk of some flooding.
The public are urged to listen to weather reports and expect some minor delays due to slower traffic.
