Igor, Julia & Karl together with the rest of this season have made quite a bit of history this week!

The last time two Cat 4s were spinning at the same time was on Sept. 16, 1926, when Hurricane No. 4 (that’s how they were named back then) and the Great Miami Hurricane were in existence.

(In that same year, George Burns married Gracie Allen, the children’s book Winnie-the-Pooh was first published, and Calvin Coolidge was president.)

– Another indicator of how rare this is: Two major hurricanes (Category 3 and higher) been in existence simultaneously only nine times since 1900, with the most recent instance being with Floyd and Gert in 1999.

– With Julia, this year has now seen four Category 4 hurricanes emerge by 5 a.m. on Sept. 15, the earliest that has happened since record keeping started in the mid-1800s.

– The emergence of Tropical Storm Karl, the 11th named storm of the season, on Tuesday made this a busy year to date. The only years more active this early in the season were 2005, 1995, 1936 and 1933.

– All of this year’s four Category 4 storms emerged in just twenty days, which is the shortest time span for that to happen. The previous record was 24 days in 1999, according to Phil Klotzbach of Colorado State University.

* Just a footnote to the article sourced above: Igor, not Julia, is the most intense tropical cyclone in the ATL so far this year (and for both highest wind speed as well as lowest pressure).
