Site Update (May 1st 2013): All weather maps have been improved to make them much more useful for climbers. Animate either temperature or weather and move your cursor to any mountain location to see how the weather is forecast to evolve at various elevations. Because of the limited space on these large region maps, we can only show this at a subset of locations. We will add much more detailed maps very soon.
