Storm Clodagh is set to batter the Province today with a yellow wind warning in place until 8pm.
Met Office forecaster Greg Dewhurst said it “will sweep through (Northern Ireland) quite quickly”.
He said Storm Clodagh will be accompanied by “heavy showers”.
“You are likely to see gusts of 50mph-60mph but you are also likely to see gusts of 70mph around the coast and over the higher ground.
“There is a yellow wind warning in place until 8pm which is the least severe, but obviously a warning is a warning and it is still important.”
He said the “wind will strengthen this afternoon and into the evening” but forecasters are “not expecting any widespread flooding”.
Temperatures will drop tonight and “we could possibly see the showers starting to turn wintry over higher ground turning into sleet and snow through this evening and overnight into Monday”, added Mr Dewhurst.
“It could be quite treacherous in parts of Northern Ireland tomorrow so it is definitely a time to keep and eye on the weather forecast.
“Winter is coming on higher ground tonight in Northern Ireland and could cause travel disruption.”
The forecaster said Monday will be drier in the Province in the afternoon but will “stay cloudy with sunny spells”.
“You will see the return of further rain into Tuesday morning to give another spell of wet weather,” he added.
“This will clear into Tuesday afternoon though it won’t be as bright with further patchy rain. It will turn quite windy once again on Tuesday with gusts of up to 50mph and perhaps locally 60mph.”
He said the “unsettled period” would persist overnight and into Wednesday.
“Thursday will be brighter and not as windy,” he added.
“But at the end of the week it turns windy again with further rain.
“We are keeping a close eye on the situation and it would be good for people to keep tuned to the forecast.”
