Simultaneous Major Hurricanes

[hurricanes1234]

Was there ever a time between 1997 and now in the eastern north Pacific when two major hurricanes were active simultaneously? For example, two hurricanes that were Category 3s, 4s or 5s at the same time, like Igor and Julia in 2010 (though these were in the Atlantic). Thanks!

While this straddles the EPAC/CPAC areas of forecast responsibility, I found this after looking for a few minutes...

KENNETH 13.40 -130.50 09/19/15Z 100 960 HURRICANE-3

As you can see in the data, and in the following two images, Kenneth was already past peak and weakening, while Jova was intensifying.

Thanks everyone!

On June 25, 2010, Hurricanes Celia and Darby were active. Celia weakened from its peak as a Category 5 hurricane, but was still a major, and Darby had just become a major.

[hurricanes1234]

Thanks Hurricanehink!

Also, Ioke and Illeana in 2006 IIRC.

Don't know why you restricted yourself towards post-1997.

I was using the NRL Monterrey Website which only displays as far back as 1997.

Nah, Ioke dropped to a Category 2 briefly when Ileana became a major.

[supercane4867]

Don't know why you restricted yourself towards post-1997.

Talking about pre-1997, Kenneth and Lidia in 1993 both attained peak intensities of 130kt at the same time

Should be the strongest Simultaneous Hurricanes ever recorded

[Hurricaneman]

What about Iniki which was CPAC and Andrew in 1992, both were cat 4 at the same time and the fact that it was the CPAC and Atlantic having a cat 4 at the same time has to be some kind of historical significance

[hurricanes1234]

Thanks! I think it would be very interesting if we get two Category 5s at the same time in the same basin. Especially if they are open water fishes in the EPAC, oh! It doesn't get more interesting than that.

Well, if you're talking about just the same basin, I don't know if SuperTYs with the intensity of Ivan (155kt) and Joan (160kt) from 1997 had ever simultaneously existed before (they hadn't since reliable analysis tools or satellite existed), or will ever be seen, in such close proximity, again in my lifetime.

Wow! That's absolutely stunning. The WPAC always comes in front of every other basin when it comes to strength and records!

[euro6208]

Another view of twin Category 5 Ivan and Joan. Both systems reportedly reached a dvorak number of 8.0.

Gives you an idea what a strong el nino can bring to our area and were part of 10 category 5 that year.

[hurricanes1234]

Good thing we got this in recent times, or else we would have no images! I can't imagine what it would be like to have a season with 10 Category 5s in my lifetime.

Thanks very much to all those who have contributed and who may do so in the future. It is much appreciated!

[Ptarmigan]

I notice simultaneous major hurricanes in the Pacific occur during warm Pacific Decadal Oscillation (PDO). 1993 was Neutral ENSO bordering into El Nino.

That's 3 Major Hurricanes...
