I was forwarded this photograph that purported to show snow in Sri Lanka.
As soon as I saw it I was skeptical. The catch is that Sri Lanka is a tropical island that is just a few degrees north of the equator, somewhat like Hawaii in climate, so snow would be very unusual even given the erratic weather patterns caused by climate change. Furthermore, I lived for many years in the area shown in the photograph and I cannot recall even needing a sweater at any time. It is at an elevation of less than 2,000 ft above sea level.
My initial reaction was that this is one of the many doctored images that float around the internet, especially since there was no sign of snow on the trees or on top of the cars and buildings.
But a friend in Sri Lanka says that while it is not snow, it is not a hoax either, that the material used to resurface the roads results in a soap-like foam emerging after it rains. This apparently happens all over the globe but I have never encountered it myself.
Has anyone observed this?
