In total, there were sixteen tropical storms during the season, of which five (Tropical Storm How, Tropical Storm Mike and three unnamed tropical storms) did not attain hurricane status. Overall, six major hurricanes occurred during the year. The Hurricane Hunters made about 300 flights into hurricanes during the season, the most since the practice began in 1943. The number of storms was above average; in a typical year, eleven tropical storms, six hurricanes, and between two and three major hurricanes take place. With the numerous major hurricanes, the season produced a high accumulated cyclone energy (ACE) of 211, although it was originally assessed as 243 before reanalysis. At one point, the 1950 total was the highest on record, before being surpassed by the 2005 season. This value is an approximation of the combined kinetic energy used by all tropical cyclones throughout the season.
