All counties will be affected by a low temperature and ice warning coming into effect this evening (Thursday, November 30), Met Éireann has said.
Temperatures are expected to fall below -3° in many areas, and developing frost and ice will cause hazardous travelling conditions.
The Status Yellow low temperature and ice warning for Ireland will come into effect at 5:00p.m today and will remain in place until 12:00p.m tomorrow (Friday, December 1).

A Status Yellow low temperature and ice warning for Ireland will be in place between those times, with hazardous conditions on roads and paths and travel disruption.
