At this website, tropical depressions are identified by an alphabet for
users' convenience. This alphabet is not assigned in chronological order.
When tropical depressions have developed to tropical storms, typhoon
numbers are assigned instead.
When a tropical cyclones is expected to become a tropical depression
or an extratropical cyclone during the next 3 to 5 days, a forecast up
to the next 4 days is issued.
