Blowing snow

Blowing snow[1] is snow lifted from the surface by the wind, at eye level (1.8 m or 6 ft) or more,[2] that will reduce visibility.

Its METAR code is BLSN.

If the snow remains below 1.8 m (6 ft), it will be called drifting snow (METAR code: DRSN).

The snow which is being blown about may deposit as snowdrifts.

There are 3 ways of producing blowing snow:
