Previously, there was a button to disable pressure systems on the website. I can't find it anywhere anymore. I had turned it off in my computer before, because I find them too striking out from the map, and the are also not available in all maps back to 1979, and instead only in some recent years. I am not interested in tracking locations of various pressure systems all over the world from years ago, so I think that there should be an option to disable them.
