A status yellow snow-ice warning has been in place for the entire country since yesterday morning, and is set to last until Saturday.
It's resulted in very cold conditions nationwide, with widespread frost, ice and snow in places.
#Sneachta has been trending online since the snow first started hitting.
Here are some of our favourite pics throughout Ireland:

Some scenes in Donegal look spectacular:

WESTMEATH
The snow has spread as far as the Lake County in the midlands:
GALWAY
Galway is only beginning to get a few sprinkles of snow, but it is visible atop the Maumturk Mountains:
So #Galway has got its first bit of #snow in 2019, albeit only a small amount. The snow capped Maumturks look picture perfect (not that they weren't already!!), don't ya think? This beautiful photo was captured by Matt Casey 😍🌨️❄️ #Sneachta #BeCarefulOutThere #Icey #VisitGalway pic.twitter.com/WSjXC6jo9P
