How rare Category 5 typhoons hit East Kanto = Chiba & Ibaraki? It's like once in 5 years?. I'm scared high wind of Cat 5 breaks some branches of our citrus trees.

You can see the eye easily on the satellite. Also, you can see the "end of summer" stationary boundary cloud to the north of the Japanese Pacific coast. This is likely to be disrupted by the typhoon.
HOWEVER, this stationary boundary cloud is likely to provide a convergence of cloud, a little like the floods of early July, so there could be excessive amounts of rain.

The end of summer stationary boundary seems to have appeared on the weather maps in the last week or so.

In about May, the "rainy season" stationary boundary starts off near the Philippines and moves slowly north, hitting southern Japan about early June, and central Japan about mid June(usually about 4-6 weeks duration). It eventually passes slightly further north, where it then dissipates about in early/mid July. This ended early this year, around late June.

In September, the stationary boundary and rain appears again for about a week, heading south. When it moves through, the cooler air follows. This usually happens in the 2nd or 3rd week in September, but many of these normal processes seem to have been happening earlier in the last year.

Here's the map:

You can also see it on the Korean map as a rain boundary.

The stationary boundary has now almost passed through to the south. In June/July it normally takes 3-4 weeks, heading north. In September, it usually takes less than a week.
Yesterday in Tokyo it was 31.4C, today it looks like it will only get to 26C. However, the typhoon will disrupt all of that.

Typhoon Jebi is currently in an "eyewall replacement cycle". The eye disappeared yesterday, but you can just see it reforming in the latest image, and it looks like it might be a big eye.

It's 2018's strongest storm, peaking the day before yesterday at a sustained 279kph, low pressure of 915hPa.(It was probably gusting to around 335kph). You can see the outer bands on the northern side catching up with the stationary boundary over Japan.

201809012320-00.png


Jebi has weakened slightly from two days ago of 275kph gusting to 330kph, to now 240kph, gusting to 293kph.

Hard to get the head around that strength...do you happen to know what the highest recorded wind speed was for a Typhoon that made landfall over Honshu?

I think it may have been Typhoon Nancy in 1961. Winds to 340kph, and winds to around 170kph when it made landfall in Honshu.

Eye wall replacement seems to be complete.

Winds have eased to low Cat4, 200kph gusting to 240kph

I wonder what the surf is like at this spot at the moment?

There's currently a high wave warning for much of the Pacific coast, except northern Honshu.
It was actually bigger a couple of weeks back before the two consecutive typhoons, when we had about a week of strong southerlies, which was unusual.

Dangerous levels of rainfall in Shikoku with Typhoon Jebi already.

Coastal town of Tano in Kochi Prefecture has had 92mm of rain in the last hour, and 120.5mm in the last two hours.

Up in the hills not far away, Yanase has had 63.5mm in the last hour, and 132.5mm in the last 3 hours.

In Muroto-misaki, Kochi prefecture, winds gusting to 199kph(sustained winds to 172kph), and to 165kph in Nanki-shirahama, Wakayama prefecture.
Lowest pressure seems to be 955.3hPa.

These are the strongest winds I've seen in Japan.

The guys doing my building decided to do all the high work today rather than later this week because of the impending weather. The clouds have just rolled an the temp has dropped. The wind is increasing.

It's the 24th anniversary for Kansai air port today. It was opened on September 4th,1994. Amazing video, this was filmed at the airport today.



I wonder if the hotel is open? You would probably feel like you were on the good ship Nikko if it is.

Kansai airport....

Strongest typhoon to hit Japan in 25 years: confirmed.
Kansai airport runway is flooded & without power. Thousands are stranded there, because a tanker has been driven against the bridge connecting the mainland, damaging the bridge.
Thousands evacuated and millions without power.
I'm not sure what the highest gusts were, but I earlier posted that Muroto-misaki, Kochi prefecture, had winds gusting to 199kph(sustained winds to 172kph).

Jesus that's hectic. I've flown out of there a few times .

I wonder if any provisions were made in the design for a event like this..?

Didn't someone mention the island was sinking previously?
The damage to the bridge looks pretty bad. Kansai could be closed for quite a while.

The airport is on hydraulic rams, which compensate for the expected sinking. However, it sinks faster than expected, sinking as much in the first 6 years as was expected in 50 years.
This is not sinking, it's flooding by storm surge. The worst aspect is that the basement level is flooded, cutting power. I suppose it also means that for the time being, the hydraulic rams are not powered either.

Look closely at the second clip of the woman trying to stop her roof top shed disappearing. One lucky lady.

I saw that on the news last night. While the wind and the vehicles are just amazing, the best part are the typical woman's and the man's noise effects!!!! ;)

They are speaking typical Kansai-ben, and somehow I hate Kansai-ben:confused:.

It seems ferris wheels can be a lot more exciting than roller coasters when a typhoon is coming:eek:

Drove between Madarao and Akakura last night. We had quite a bit of wind and rain earlier. There were places where the road was completely covered in tree debris.

Today is calm and sunny.

Seeing all the carnage in other places is quite scary. The trucks that have just blown away has to be seen to be believed.

Local media are reporting Osaka bay set the highest tide level of 329cm yesterday. The second highest one is 293cm, which was recorded when a super strong typhoon hit Osaka area in 1961.

That was a storm surge. However, if the normal tide coincides with the arrival of the typhoon, then you can get near record high water.
For example, yesterday, the nominal high tide in Osaka was about 4pm. The low tide was around 8:30am, so tide was rising to near maximum from around 2pm, just as the typhoon was arriving.
Had the typhoon arrived at 8:30am, the airport probably wouldn't have been flooded.

I have a girlfriend arriving on Friday night. She is meant to be flying out via Kansai in about 4 weeks time. Will be interesting to see what happens.
