Clouds and Weather

  • Cloud height sensors reach about 12,000 feet above the ground. At major airports, this information can be augmented by a trained observer.
  • This can sometimes mean that conditions are clear, when a cloud base is above 12,000 feet.

Decoding Cloud Information:

  • Up to 3 layers (the lowest 3 layers) of clouds can be reported.
  • The first 3 letters of a cloud group describe the amount of sky coverage. The last 3 numbers indicate the base of that layer, above the ground x 100 feet.
  • SKC: Sky Clear.
  • CLR: No clouds below 12,000 feet above ground level, as detected by automatic equipment.
  • FEW: Few Clouds - Between 1/8 and 2/8 of the sky is covered by clouds.
  • SCT: Scattered Clouds - Between 3/8 and 4/8 of the sky is covered by clouds.
  • BKN: Broken Clouds - Between 5/8 and 7/8 of the sky is covered by clouds.
  • OVC: Overcast - 8/8 of the sky is covered by clouds.
  • VV: Vertical Visibility - An indefinite cloud ceiling caused by fog, rain, snow, etc.
