This is Hank Harley calling from Whoville. I have just sighted a funnel cloud in a storm about 5 kilometers to my north. It was visible for 2 minutes at 5:36, but seems to be disappearing now. The storm is moving from the southwest at about 50 km/h and was accompanied by high winds and small, pea-sized hail. I didn't see any damage.
