Simultaneous Major Hurricanes

[Yellow Evan]

Well we now have 3 major Tc's in the E/CPAc. Incredible.

[HurricaneBill]

It always amazed me that despite how active the Atlantic was in 2005, the EPAC still managed to have a parade of storms (Jova, Kenneth, and Max).

Gotta add Lester and Madeline to the thread!

In this picture, Lester (right) was a Category 4 and Madeline (left) was a Category 3...

Another recent example of simultaneous majors that has inadvertently slipped under the radar, only because one storm largely overshadowed the other, occurred in the Eastern Pacific on October 23rd, 2015. On the same day that Patricia was going crazy, Olaf also regained SSHWS Category 3 intensity. The two combined for one of the largest basin ACE days that I have come across in my work so far, trailing only WPac October 17, 1997 (Ivan and Joan), EPac August 30, 2015 (Kilo, Ignacio, and Jimena), and WPac October 18, 1997 (Ivan and Joan again).


(credit for the image goes to supercane4867; I swiped it from one of his posts in the Olaf thread)

Some other big days involving simultaneous major tropical cyclones that I have come across and are worth noting are as follows:

WPac September 9, 1987 (Gerald, Freda and Holly, as previously mentioned by mrbagyo).

WPac November 27, 1990 (Page and Owen, dual Category 5s, with Category 4 Sina also visible from the SPac).



WPac November 20, 1992 (Hunt and Gay).



WPac July 11, 1972 ((non-major) Susan, Rita, Phyllis, and (not yet major) Tess).



EPac September 11, 1993 (Kenneth and Lidia, as previously mentioned by supercane4867)

ATL September 15, 2010 ((not yet major) Karl, Igor, and Julia).



*Edited to clean up storm ordering and match their locations in the images.

A couple others:

WPac October 11, 1979 (Sarah and Tip)



WPac October 24, 1994 ((non-major) Teresa, Verne, Wilda, and (non-major) Yuri)

How about Matthew and Nicole, I know theres some pictures out there

How about Matthew and Nicole, I know theres some pictures out there

I distinctly remember that after an initial bout of RI (to category 2), Nicole spent a considerable amount of it's early life under strong upper level NW or WNW shear from the large upper level anticyclonic outflow envelope of Matthew, weakening to a TS, albeit a tenacious one. It wasn't until Matthew had moved out of the picture and become a PTC that Nicole went to town, becoming a Cat-4 Hurricane.

I've seen a lot of imagery of Nicole and Matthew around the time that Nicole first hit cat-2, however it pales in comparison to the others already posted in this thread.

How about Matthew and Nicole, I know theres some pictures out there

I distinctly remember that after an initial bout of RI (to category 2), Nicole spent a considerable amount of it's early life under strong upper level NW or WNW shear from the large upper level anticyclonic outflow envelope of Matthew, weakening to a TS, albeit a tenacious one. It wasn't until Matthew had moved out of the picture and become a PTC that Nicole went to town, becoming a Cat-4 Hurricane.

[best track data removed for spatial reasons]

I've seen a lot of imagery of Nicole and Matthew around the time that Nicole first hit cat-2, however it pales in comparison to the others already posted in this thread.

If you're curious, here is a GOES-13 full disk IR image from 03Z October 7th, 2016 of the two. As AJC3 mentioned though, Matthew and Nicole never did exist as simultaneous majors.

Here's a few more, beginning with WPac August 19, 2015 (Goni and Atsani). The dual large eyes on the category 4 and category 5 (respectively) make this one of my favorite cases.



These images kinda suck since the storms are near the edge of both disks, but Susan and Ron of the SPac are the third and final case I am aware of dual Category 5s (after Paige and Owen and then Ivan and Joan). Here they are together on January 6th, both near peak intensity, from GMS-5 and GOES-9.





Olaf and Nancy also existed as dual category 4s in the SPac between February 14-15, 2005.
