The Northwest Pacific typhoon season runs throughout the entire year, but the main season tends to occur between July and November, with peak activity in late August and early September. According to the Guy Carpenter Asia Pacific Climate Impact Centre (GCACIC), the 2008 season was considered to be relatively inactive, with the total numbers of tropical storms being below average (see Figure 1). The 2008 season saw the formation of a total of 22 named tropical storms (four more were considered as having attained tropical storm intensity by the Joint Typhoon Warning Center, but no name was given by the Tokyo Regional Specialised Meteorological Center, RSMC), of which there were 12 typhoons and five major typhoons.
