Double eyewall?

Geez...that's a classic example of a concentric eyewall structure. It will probably start to weaken over the next several hours as the inner wall breaks down and gets replaced by the outer wall.

Wow. Hope we don't see something like that in the Atlantic.

Still might be 100 mph in Japan. Very dangerous situation if it hits at 100 mph.

It's an Eyewall Replacement Cycle. Once it's done, and the outer eyewall contracts, there's a chance that Dianmu will be even stronger than before.

watch it hit 200 mph.

IF it hits Japan. It's been running west of the forecast track. It misses Japan itself completely on the NGP now, running to the West of Kyushu.

Perhaps more likely to hit Okinawa and then Korea.

Most storms don't peak more than once...Alan, etc. are exceptions.

It is not impossible.

[Aslkahuna]

not impossible but probably not likely. The main threat from the storm to areas north of Okinawa will be heavy rains and severe flooding since the storm will be interacting with the Polar Front once it gets north of 30N.

100 mph is dangerous though.

[FWBHurricane]

The threats from this storm isnt just Heavy rain and flooding...the winds are going to be up to about 105mph...anything past 100mph can do some considerable damage. This storm is going to keep heading NNW nad then in about 48 hours it will turn sharply due North to a slight NE direction and speed up, striking southern Japan as a Strong Category two maybe weak category three.

Dangerous, look at that amazing eye. I hope that image is archieved forever.

Holy Crap!!

Does anyone know what the strongest typhoon to hit was? What were the highest winds an lowest pressure? Just curious.
Thanks!

I think it was Super Typhoon Tip in 1979 that hit mainland Japan. It had winds gusting as high as 190 mph (306 km/h) and a central pressure of 870 mb (25.69"Hg).

This researcher (from this year's Hurricane Conference) thinks it may have been Supertyphoon Angela:

"Have there been any typhoons stronger than Super Typhoon Tip?"

There's an attached PDF that goes into more detail. Since recon has stopped everything is through the Dvorak technique, and he feels Angela looked better on satellite.

Supertyphoon Tip did not have record winds, it had record low pressure (that was measured by Recon; a few storms very well could have surpassed it, but no Recon had been able to prove that). It hit mainland Japan as a minimal typhoon at best.

The Philippines have had the most supertyphoon landfalls. Zeb in 1998 hit Luzon with 155 knots. So did Angela in 1995. Joan hit the same area with 150 knot winds in 1970. Sally in 1964 passed just to the north with 160 knots. Many other supertyphoons and countless typhoons had hit this area.

The late 1950's had many incredibly strong supertyphoons. Joan in 1959 hit Taiwan with 165 knots and a pressure of 885 mb. Gilda in the same year hit the Philippines with 165 knots and then Vietnam with 90 knots. Lola in 1957 passed very close to Guam with 150 knot winds.

Wow, so many incredible supertyphoons. The strongest winds were from Joan and Gilda in 1959, both 165 knots at landfall. Japan does not normally get supertyphoon landfalls, thanks to the colder water in the area, although there have been a few, including 140-knot Vera in 1959.

Hmmm...many of those years were very active or notable Atlantic years as well.

1998 - Georges strikes Puerto Rico, the Keys and the Gulf Coast
1995 - Most Active season in the Satellite Era
1964 - Cleo soaks South Florida

Take your pick in the 50's. Lots of notable seasons for the Atlantic.

Wonder if there is a connection.

Interesting...
Season numbers:
1957-8/3/2
1958-10/7/5
1959-11/7/2
1958 and 1959 were active hurricane-wise, 1957 not as much.

Major U.S. landfalls:
1957-Cat. 4 landfall (Audrey) near TX/LA border
1958-Cat. 4 brushing (Helene) SC/NC coast
1959- Cat. 4 landfall (Gracie) GA/SC coast

The first 2 years also had a Cat. 5 "fish" in the Eastern Atlantic.

All in all, these were relatively active years in the Atlantic, just like in the WPAC.

[Aslkahuna]

WPAC is tied to the ENSO though in a different manner. During the development phase of a warm event, as the warm waters shift eastwards, WPAC tends to become very active with the areas of formation shifting east and a larger number of Supers. In post warm phase years, the activity levels tend to be low and the areas of formation shift west.
