I believe its 060 grįšur (degrees in Icelandic) 30 gust 50kts as a wind reading only from Arnarnes. I might be full of **** but believe it's the most likely explanation and would make sense to give that information given the surrounding area. Takeoff in this kind of wind would NOT be allowed.
Have been there a few times and it can be really tricky to fly in there in windy conditions... makes LPMA/FNC or Kai Tak seem to be a walk in the park.
