Will the flight be cancelled in heavy snow?

The flight will be cancelled in this weather.

The visibility of the airport is seriously reduced in snowy days, which affects the pilot's line of sight. Under normal circumstances, when the visibility is less than 800 meters long, the flight crew can't land and take off normally due to the obstruction of sight, and the lower visibility may even lead to the inability to taxi.

If it is not handled properly, it will easily lead to flight accidents. At this point, the airport had to be closed, resulting in flight delays or cancellations.
