Mist is reported when visibility is reduced due to the suspension of water droplets in the air, but visibility is equal to or exceeds 1,000 m (~5/8 statute miles)
Mist typically dissipates more quickly than fog and can rapidly disappear with even slight winds.
The abbreviation “BR” is possibly derived from the French “brume”.
