London is set to see temperatures drop with sharp frosts as a northerly airflow is set to bring arctic air to parts of the UK.

There will be winter sunshine across London today (Monday), leading to a very cold night with widespread sharp frosts.

With cool conditions in charge and the potential for snow and ice for some from Sunday onwards, travel plans could be impacted.

The UK Health Security Agency has a Cold-Health Alert in force, which highlights that possibility of significant impacts for the health and social care sector. 

The ongoing weather alert, effective for several days, is projected to continue until January 18.

Special emphasis is placed on urging vulnerable individuals, particularly those aged 65 and above, to exercise additional caution and take necessary precautions during this period.
