It was numbered off on 1949-07-30, with 27 track points recorded throughout its lifespan.
Numbering note: The unified international numbering system for the Northwest Pacific has been assigned by JMA in Japan, the designated regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1949. The number 194908 is the historical number used by the CMA. JMA in Japan, the Joint Typhoon Warning Center in the United States, and Chinese meteorological agencies may have assigned different numbers to the same typhoon that year, so the numbers cannot be compared directly.
