The 2020 Atlantic hurricane season has been hyperactive with 25 named storms, including nine hurricanes, spinning across much of the Atlantic basin. Those storms have set several records through early October.
Here's a look at what we've seen so far.
22 Named Storms Were the Earliest to Form on Record

For perspective, the average formation date of the Atlantic's 9th named storm is Oct. 4 for the years spanning 1966 to 2009, according to the National Hurricane Center. We are 16 named storms ahead of that pace as of early October.

Nine named storms have made a mainland U.S. landfall this season, and four of those were hurricanes.
The nine mainland U.S. landfalls tie 1916 for the most on record in a season, according to Dr. Phil Klotzbach, a tropical scientist at Colorado State University.
Hurricane Delta is likely to break this record as the 10th U.S. landfall later this week.

The month of September has had 10 named storm formations through Sept. 21, which is the most on record for the season's busiest month.
September's previous record for the most named storm formations was eight in 2002, 2007 and 2010, according to Klotzbach.

3 Storms Form in Single Day, Tying a Record
Sept. 18, 2020, will be known in history for a frenetic burst of three Atlantic named storm formations in just six hours.
Tropical Storm Wilfred formed in the eastern Atlantic Ocean that morning. That was followed by Subtropical Storm Alpha developing just prior to landfall in Portugal, and then Tropical Storm Beta spinning up in the Gulf of Mexico.
Klotzbach said Aug. 15, 1893, was the only other day in which three storms formed on the same calendar day.
Atlantic Had 5+ Tropical Cyclones at One Time
The Atlantic had five active tropical cyclones for a brief time on Sept. 14, including Paulette, Rene, Sally, Teddy and Tropical Depression Twenty-One. While that's not a record, it's only the second time the Atlantic basin has had five or more tropical cyclones at one time.
Sept. 11-12, 1971, holds the record with six tropical cyclones active at once in the Atlantic, Klotzbach tweeted.
