From Phil Klotzbach:
According to the monthly data that I have since 1950, December 2005 has now posted the highest NTC of any December on record with 8.8%. It broke the old record of 7.7% set in 1984. December 2005 also has the record for most named storm days (7) and hurricane days (5.25) ever in a December.
