Here's a link to the PDF:

On Page 5 is the following:

The following rules apply for tropical cyclones passing from one basin to another: Retain
the name if a tropical cyclone passes from one basin into another basin as a tropical cyclone; i.e.,
advisories are continuous. An unnamed tropical depression will also retain its number (e.g.
Tropical Depression Six-E remains Tropical Depression Six-E) if it crosses into another area of
responsibility. For unnamed tropical depressions moving from west to east across 180°, CPHC
will use the associated Joint Typhoon Warning Center’s (JTWC) number and indicate JTWC in
parentheses following the number. For named systems, CPHC will use the associated (RSMC)
Tokyo name and provide the associated JTWC number in parentheses.
Within a basin, if the remnant of a tropical cyclone redevelops into a tropical cyclone, it is
assigned its original number or name. If the remnants of a former tropical cyclone regenerate in
a new basin, the regenerated tropical cyclone will be given a new designation.
