To what extent can it snow to stop classes?

If the snow reaches Grade 4, red warning signal can suspend classes due to the snowstorm.

Blizzard red warning signal is a severe weather warning, which means that in the next 6 hours, the snowfall is expected to reach more than 15mm, or it has snowed more than 15mm and the snowfall is still continuing. In this case, heavy snow may have a serious impact on traffic, leading to road icing and low visibility, and increasing the risk of traffic accidents. At the same time, heavy snow may also have a greater impact on agricultural production.

After the red blizzard warning signal is issued, the school may take measures to suspend classes to ensure the safety of students. This is because heavy snow may cause traffic jams and students may have safety problems on their way to school. At the same time, heavy snow may also affect school facilities, such as power supply and heating system. Therefore, after the release of Blizzard red warning signal, the school will decide whether to suspend classes according to the actual situation to ensure the safety of students and faculty.
