There are some spam issues in the comments, so I had to disable comment editing for a short time. It'll be back once the spam bots are gone. FYI... they leave a comment with "great" and then edit in the spam stuff later, to get around the filter.
(Think of it as a "light" thunder storm. Germany has well tempered weather. A really stormy storm is der Sturm. It's a nice example for "ge-" meaning "collection of"... collection of weather.)
