    Very hard to get verified data from Nicaragua, NHC mentioning how most of the weather equipment was put out of action from the last Hurricane. Flooding seems to be the biggest issue.

    The 2020 Atlantic hurricane season officially came to a close yesterday, though the odd sporadic system cannot be ruled out over the next month or two (no signs of anything in the immediate future).

    Statistically speaking, it had a record number of named systems (30), which was two more than the previous record of 28 in 2005 and ten more than the next highest year, 1933. Of these, 13 became hurricanes, 6 of which were major (Cat 3 or above). This was less than 2005, when there were 15 hurricanes, with 7 major. In fact, despite the record number of named systems this year, the average activity of each (as measured by ACE) was very low (5.99/named system), less than a third of the highest year on record, 1926 (20.9/named system), and significantly below 2005 (8.76/named system). Of the 30 named systems, 14 failed to reach max intensity >50 knots.

    The most intense storm in terms of windspeed alone was Iota back in mid-November (140 knots, 4.5 named storm days, 2.5 hurricane days, 1.25 major hurricane days, 12.7 total ACE), but the most intense in terms of total ACE (which combines windspeed with duration) was Teddy in mid-September (120 knots, 9.0 NSD, 7.25 HD, 2.75 MHD, 27.8 total ACE).

    The weakest storms were Bertha (May) and Alpha (mid-September), both of which only reached 45 knots, 0.5 NSD and 0.4 ACE).

    In terms of overall season ACE, 2020's value of 179.8 ranks 13th in the 172-year record. It was 72% above the 1980-2010 average of 104.2.

    2020 stats up to 1st December, with 1980-2010 averages in brackets.


    |2020|Rank|Record
    Named storms|30 (11.9)|1st|2020
    Named storm days|118.0 (58.2)|4th|2005
    Hurricanes|13 (6.4)|2nd|2005
    Hurricane days|34.75 (23.9)|30th|1893, 1995
    Major hurricanes|6 (2.7)|Jt. 2nd|2005
    Major hurricane days|8.75 (6.2)|Jt. 28th|1926
    Total ACE|178.9 (104.2)|13th|1933
