Given that they mention Typhoons, we can deduce that the books are being printed in Asia somewhere. It looks like Japan, Korea, China, and the Philippines have been hit this season along with some other smaller countries thrown in. India has only gotten tropical depressions.
The region where the printer is has been hit by two typhoons recently. I am thinking, given the path of the storm, that Typhoon Muifa was one of them.
Take a look at this:
Muifa is a cool name by the way. Our next hurricane/storm will be called "Jose". The typhoon season is supposed to last until November. Perhaps the breviary will be done in time for Christmas?
