I was just reading about that crazy hail storm in Guadalajara Mexico yesterday. The NBC story that I just read said that more than 3 feet of hail fell. I don't believe that for a second, I'm sure that low lying areas where water pooled the hail was over 3 feet not a general 3 foot hail coverage. Never the less very impressive. The city is at 5000 in elevation which helps. We never have deep hail here in New England as they do out in the plains. I'm sure elevation helps in that regard.
Here is link with some very impressive pictures to the hail story.
