The National Hurricane Center is changing its box score for 2013, adding one storm.
The center said Tuesday that, as part of its routine post-season review, it concluded a short-lived low that developed south of the Azores in early December, a month after the season’s official end, was a subtropical storm.
That changes the total from 13 tropical and subtropical storms to 14. Even at that, the season remains one of the quietest in decades.
Only two storms, Ingrid and Humberto, even turned into hurricanes at all; that was the lowest total since 1982.
And for the first time in 19 years, there were no major hurricanes, at Category 3 or higher on the Saffir-Simpson Scale, with top sustained winds of at least 111 mph.
The 14, two and zero compares with a historical average of 12, 6½, and two.
The 2013 season is only the third below-average season since 1995 and was the first in 45 years in which no storm was stronger than Category 1.
The 2014 hurricane season runs from June 1 to Nov. 30.
