Gardaí have advised people living in Donegal to stay indoors from 4pm onwards as Storm Emma edges closer to Ireland.
Met Éireann issued a status red warning of snow and ice for Donegal on Thursday afternoon.
The warning is valid between 1:00pm on Thursday and 6:00am on Friday.
"Forecasters predict the nation is to be hit with blizzard like conditions with zero visability later tonight which will extend countrywide," said a Garda spokesperson.
"Everyone across the country has been advised to stay indoors from 4pm today due to Storm Emma/Beast fom the East. Remember to check in on elderly and vulnerable neighbours," added the spokesperson.
A red status warning is described by Met Éireann as: "The issue of RED level severe weather warnings should be a comparatively rare event and implies that recipients take action to protect themselves and/or their properties; this could be by moving their families out of the danger zone temporarily; by staying indoors; or by other specific actions aimed at mitigating the effects of the weather conditions.
All schools across Ireland remain closed.
