Primary schools in Bradford district have been forced to close or open late over dangerously icy conditions.
One school said it is "simply not safe" for children while another said it was unable to open on time.
The UK Health Security Agency (UKHSA) has issued its amber cold weather alert for Yorkshire until Friday (January 19).

It followed a visit by their site supervisor at 4.50am.
Riddlesden St Mary's CofE Primary School
Riddlesden St Mary's CofE Primary School said the site was "simply not safe" for pupils.

A further update is expected on Bradford Council's school closures list by 8.30am.
A school spokesperson said: "Morning everyone. Unfortunately, despite gritting, we are unable to open on time today due to rain overnight and freezing temperatures.
"After completing a risk assessment this morning, it’s simply not safe. Therefore, we are going to delay opening until 10:00am today. Breakfast club will be closed. Once the staff team are in safely, we will reassess and do all we can to open at 10:00am.
