Some schools in Wales have announced their closure this morning after temperatures dropped to -8C in parts of the country overnight. Pembrokeshire Council has announced the closure of a number of schools, while Aberdare Community School has been closed due to issues with the heating system.
Temperatures across Wales dropped to well below freezing during Sunday night for many areas and drivers have been warned of "extremely dangerous" driving conditions. Dyfed Powys Police has warned that some back roads in Pembrokeshire may not have been gritted.
It is expected to remain "bitterly cold" this coming week, according to BBC weather presenter, Rhian Haf, with widespread frost this morning and icy patches on untreated surfaces. While it is slightly milder around the coast, Rhian added that some places will not rise above freezing.
