Arcus cloud - 30.7.2016 at 19.44 Ilmajoki Observation number 55049

Visibility III / V

Marko Myllyniemi, Lakeuden Ursa

On the way home, I saw that there seemed to be quite a threatening looking cloud on the left side, and when I got there I said yes this is a pretty clear avalanche, even though it was already close enough that it wasn’t quite as spectacular as if it had been noticed at an earlier stage.

Figures 2 and 5-7 panoramic images (combined from several images with Autopano Pro and post-processed in Photar).
