2020 Hurricane Season breaks numerous records
ATLANTA - From the beginning, meteorologists were forecasting an above-average Atlantic Hurricane Season. In the end, since the 1966 satellite era, this season not only surpassed the forecast, but it also recorded the most named storms, second-most to 2005 for hurricanes (13) & major hurricanes (six), third-most for named storm days (117), and sixth-most for Accumulated Cyclone Energy (178 ... just for perspective 2005 had 250 ACE).
At the end of July, the FOX 5 Storm Team was already seeing signs that the 2020 season could have several similarities to the devastating 2005 hurricane season. In 2020, we passed almost every record from 2005, smashed other longstanding records, and several individual storms set records as well.
Here is a list of some of the records the 2020 hurricane season set:
- Most active season in terms of tropical depressions and named storms.
- Holds the record for the earliest formation date for third, fifth, and every storm after.
- Record-tying two named storms in May, and five named storms in July.
- Record-breaking most storms to have formed before August through November.
- Most active September on record with 10 named storms.
- Second season after 2005 to use the Greek-Alphabet.
- Iota was not only the latest-forming Category 5 hurricane on record, but it was also the strongest of the 2020 season
- November 2020 has already produced 20 Atlantic named storm days. November 2020 is now tied with November 1932 for the most November Atlantic named storm days on record.
- Two major hurricane formations in November.
- November 2020 has already produced 18 Atlantic named storm days. That's the second-most Atlantic named storm days during November on record, barely trailing 1932's 20 named storm days.
- Record-breaking most landfalls in the United States with 12. Louisiana alone had five.
- Record-breaking sixth straight season with at least one pre-season storm

Individual storms also set records throughout the season. One of the most memorable storms will be Iota because of how late in the season it formed and how it became the strongest November hurricane to make landfall in Nicaragua (155 mph max winds) since Eta which made landfall just 13 days before with 130 mph max winds.
Iota became the latest Atlantic calendar year Category 5 hurricane on record with max winds of 160 mph. The old record was set by the Cuba Hurricane of 1932 (175 mph) on Nov. 6. Iota also recorded a lower central pressure (917 mb) than Katrina (920 mb).

Similarily to Eta and Iota, Laura and Delta made landfall within 15 miles of each other but along the Louisana Coast. Laura made landfall on Aug 27 near Cameron, Louisiana, with max sustained winds of 150 mph and a central pressure of 938 mb, tying the 1856 Last Island hurricane as the strongest landfalling hurricane on record in the state of Louisiana since 1851 (Katrina made landfall as a CAT 3). Delta made landfall on Oct. 9 near Creole, Louisiana with max sustained winds of 100 mph.
The 2020 Atlantic hurricane has recorded six major hurricanes at Category 3 or stronger so far and four of them have formed in October or November: Delta, Epsilon, Eta and Iota. No other Atlantic hurricane season on record since 1850,has had more than two major hurricane formations after Oct. 1.
One surprising statistic from the 2020 hurricane season is that the damage cost is being estimated at $38.86 billion which isn't even close to the costliest season on record dating back to 1900. The highest damage cost was $294.92 billion from 2017.
Locally, we had impacts from a couple of the record-breaking number of storms. The two storms that had the highest impact in the Georgia area were Delta and Zeta. Delta produced a tornado outbreak on Saturday, Oct. 10th and Zeta caused widespread damage and power outages on Thursday, Oct. 29. During that time, parts of north Georgia and metro Atlanta were under a Tropical Storm Warning which was the second time on record that has happened.
