A Status Orange snow and ice warning has been issued by Met Eireann for counties Cavan, Monaghan and Donegal.
An Atlantic depression is set to cross Ireland this evening and early tonight, bringing a spell of snow on its northern flank.
This will be followed by scattered snow showers later tonight and tomorrow, Met Eireann added. At present, the main risk of appreciable accumulations is limited to Ulster.
Issued earlier today, the warning will be valid from 6:00pm this evening until 12:00pm tomorrow (Thursday, January 18).
As well as this, a Status Yellow wind warning was also issued by Met Eireann for Munster, Connacht and Leinster.
A fast-moving Atlantic depression is expected to cross Ireland this evening and early tonight, bringing winds of between 50kph and 65kph – with gusts ranging from 90kph to 110kph in many counties.
There is an increased risk of coastal flooding due to the combination of the high seas, strong winds and the low pressure, it added.
This warning will be valid from 5:00pm this evening until 3:00am tomorrow morning.
These warnings come on the back of multiple weather warnings issued by Met Eireann in recent days relating to wind, rainfall, snow and ice.
