Met Éireann has issued a yellow weather warning and is forecasting sub-zero temperatures for Monday night, with parts of Ulster and Connacht expected to see the coldest conditions. The counties of Cavan, Donegal and Leitrim could see snow accumulations and experience icy conditions.

Temperatures are set to drop as low as minus three in High Wycombe as a snow and ice warning is issued for parts of England.

Travel warnings have been issued as the UK prepares for snow, ice and plunging temperatures. National Rail said cold weather over the next few days could affect trains across the country and urged anyone planning to travel to check their journey before heading off.
