Met Éireann has issued a second warning this afternoon, ahead of below freezing temperatures which are expected tonight and early tomorrow morning.
Frost will be widespread and ice is expected on untreated surfaces.
Galway could also see some wintry showers throughout the night.
The warning comes into force early tomorrow morning, at 3am and lasts until 10am.
Before this, however, the sunny spells will make way for wind and rain, which will be heavy at times, falling as sleet and possibly snow on higher ground. There is also a risk of spot flooding. Gusts between 90 and 110km/h will occur in coastal fringes for a time. The second warning is in place from 6pm this evening until 6am.
(2/2) A spell of heavy, thundery rain, with strong southerly winds, will develop along west and southwest coasts towards evening, extending across the country later this evening and tonight, turning to sleet in places, with a risk of snow, mainly over high ground.
