Blu?

Anyone know what BLU represents in a METAR, eg:

BRIZE NORTON EGVN 142050Z 25006KT CAVOK 02/00 Q1002 BLU NOSIG
Thanks in advance,

RC

BLU is an abbreviation for the colour code "Blue".

Colour codes are issued by UK Military fields and are shorthand for the cloud and visibility prevailing at the time.

Blue is shorthand for 8K or more vis and ceiling greater than 2500

Decreasing ceilings and/or vis are represented by the descending colour series WHITE, GREEN, YELLOW, ORANGE, and RED.

The additional colour BLACK indicates that the field is closed for not wx reasons.

Hope this helps.

Thanks for that! Found more information on the Flyer website here now that I know what I'm looking for!

UK Military METAR Colour Codes

Black - Airfield closed for non-Met reasons.

Red - Cloud under 200ft, and/or Visibility under 800m.

Amber - Better than Red, but cloud under 300ft, and/or Visibility under 1600m.

Yellow - Better than Amber, but cloud under 700ft, and/or Visibility under 3700m.

Green - Better than Yellow, but cloud under 1500ft, and/or Visibility under 5km

White - Better than Green, but Cloud under 2500ft, and/or Visibility under 8km

Blue - Cloud 2500ft or above and Visibility 8km or more

'Cloud' in this case is the lowest cloudbase designated as SCATTERED or worse.
