I knew that rain was possible when I visited lake Østensjøvannet today June 3 2012 evening. Umbrella was with me and showed to be useful when a sudden rain hit the lake area. I first went to the east side and got some scenes from the wind making nice waves on the surface, swans swimming northwards. A swan with cygnets close to the high green grass and trees also was seen. When I was on my way to the west side a great show of rainbows painted the sky. The swan 96B and her neighbour more north still on the nest.
