Dianmu Advisories

[SupertyphoonTip]

It's not a problem with the radar, since reports from Naha have mostly been "light rain showers" so far. There are a few yellows and greens on an approaching band, however, and that should be the brunt of the storm for them.

The SST's beneath Dianmu cannot sustain a 105-knot typhoon and it should pass the 26C isotherm in the next 18 hours. Then, it looks like it will weaken to a 60-knot tropical storm by landfall.

[jlauderdal]

The forecast has Dianmu weakening to 125 mph then getting back up to 135 mph, and then hitting japan as a category 2-3.....

Is it coming to Florida? LOL

I figure I would be the first of the season to post this question.

Very nice indeed. Great work Chad.

There are not hundereds of millions in Korea. Be that as it may the track, if it holds, and the strength, if it held(and it shouldn't as it gets that far North)will/would still affect 10's of millions of people who are not really equipped to deal with a "super" typhoon.

I meant in all areas this storm could affect between the Koreas and Japan. Even Vladivostok, Russia is home to 700,000. And even if the storm doesn't run over North Korea, the heavy rains from Dianmu's fringe would be devastating in that 4th world country.

It looks like it's just going to swallow up Japan.

Yeah, but what a beautiful pic.

Good radar loop of typhoon Dianmu approaching the islands south of Japan . Thoughts and comments welcomed. P. S Cannot read Japanese .

Awesome! My goodness at the estimated rainfall!!

[Hurricanehink]

Fortunately, it looks to be weakening a lot. It may not even hit Japan as a typhoon.

Agree. Satellite imagery shows a slowly dying typhoon, although it could still have a few very strong winds, especially near the center. The JTWC track shows landfall at 60 knots, not as much of a huge threat anymore.

shows the telltale signature of drier and cooler air working into the circualtion which first began to show up two days ago as well as a dry slot working into the storm. Additionally, the IR signature is nowhere near as impressive.

is manned by a mix of Military and Civilian forecasters and with their relocation to Pearl Harbor, they have longer tour lengths. Additionally, some of those Military people have become and became in the past quite expert in typhoon forecasting, dynamics and analysis. In fact, the gust spread forecasts now used by both JT and NHC was originally developed by JTWC and they are the ones who developed the wind/pressure relationship for WPAC as well as several other studies including one on the extratropical surge that occasionally occurs in storms before they become extratropical.

She has taken in dry air it looks like.

[Hurricanehink]

Yea. I wouldn't be surprised if it was downgraded to a tropical storm before it hit Japan.

[SupertyphoonTip]

Well, according to the forecast, that's exactly what Dianmu will do.

I hope I never see a hurricane like that heading for the Louisiana coast! I could never imagine what would happen if a hurricane like Camille would hit the southeast Louisiana coast. You could write Houma and New Orleans off the map for sure! And if you did not evacuate far, far inland, you could kiss yourself goodbye.

Lili almost did that, except it was farther west(back near Intracoastal City and New Iberia). It would still have been devastating had it held it's Category 4 strength.

The best track for a catastrophe in Louisiana would be a major hurricane moving WNW, making landfall near the Mouth of the MS River then passing just south of New Orleans. You don't want to see that, trust me, ever, but something similar will happen one day.

If I were in S. Japan, I'd be really, scared. Especially if this was my first typhoon.

[SupertyphoonTip]

The pressure in Okinawa is rising fast after 5 hours of tropical storm force winds. Typhoon Dianmu (90 knots) is making its way to the northeast and losing strength quickly. It is not expected to affect Japan with typhoon-force winds, but up to 60 knots is still possible. There may also be heavy rainfall at times, but Japan is quite experienced with tropical storms and this should not be as big of an event as previously expected.
