While keeping a close eye on typhoon Talim, I noticed that tropical storm Doksuri is also on the map and has caused serious damage and loss of life. I had thought that the naming of tropical storms is alphabetical (within a given area) so it seems that Doksuri with a "D" must be quite old by now, and Talim fairly young.
Do I have the basic idea correct? I've tried to read the Wikipedia article Tropical cyclone naming but it gets a little complicated to read as it start to break things down by East Pacific and West Pacific and I am not sure from where these two originated.
How did a "D" and a "T" end up so close together? Is this unusual?
