Up here in the mountains spring hail storms are the norm, usually we have grape sized hail and every so often golf ball sized. 3 years ago we had a storm that produced tennis ball size hail and destroyed whole communities that are still being repaired/rebuilt. A large shopping mall was closed for over two years and only recently fully opened. My sons car was completely destroyed and I mean destroyed (written off) and his house shredded took 18 months to repair. The weather forecasters are pretty good at predicting the storms so taking cover is the rigor just like the old cold war days.
