After the Met Office issued a new weather warning for snow on Tuesday, many parts of south west Hertfordshire look like they could be getting a dusting of snow this week.

The yellow warning was issued yesterday afternoon and comes into effect tomorrow, and covers the whole of the county.

What is sure to be on many parents' - and children's - minds this week is whether schools will be open or not if snow falls.

St Albans & Harpenden Review:

If you cannot get to work because your children's school is closed and there is no childcare available, you have the right in law to unpaid leave to look after children or other dependents in an emergency.

Solicitors advise that a school being shut at short notice is likely to be considered an emergency.

Therefore, you would probably be entitled in law to a reasonable amount of time off to make alternative arrangements.

It is usually a headteacher who makes the decision on whether to close a school or not, either fully or partially, not the local authority, and they take into account factors including ground conditions, heating availability, kitchen capabilities, and how many teachers can reach the school.

St Albans & Harpenden Review:

Parents can find out if their child’s school is closed in the event of snow by checking Imodus on Hertfordshire County Council's website.

Alternatively, we will be bringing you all the latest on Thursday.
