Hi guys,

The NW pacific show up his full power, with a typhoon exploding over Saipan / Guam yesterday, slashing them and now still intensifying.

Actually is given at 155 knots with gusts to 190 knots !!!!!!!!!!! JTWC forecast a peak of 170 KNOTS with gusts to 205 KNOTSSSSS !!!!!!! What a beast, it can still reach Japan wekend as a CAT 5. Incredible storm.

AND SEE THE RADAR OF A SUPERPOWERFUL STORM LIKE THIS !!! Simply incredible :shock: :shock: :shock: :shock: :shock: :shock: :shock:

:shock: :wink:

:shock: :shock:

It reported a sustained 240.8 km/h with gusts to 277.8 km/h, then the anemometer probably flew away. The pressure fallfor another three hours there, so the worst wind is still not this. Incredible storm, and the eye do not hit Saipan but pass over Rota with its southern eyewall.

PGSN 221454Z 130130G150KT 1/2SM +RA SQ SCT004 BKN008 OVC018 24/24 A2914 RMK AO2 SLP863 P0035 60163 T02390239 55011 $=

That's really incredible ! Curios the first two fields, with 130130, without reading the "gust" one could think they made a mistake by typing twice the direction angle :lol:

When yesterday I was looking at the radar Saipan was even NOT in the eyewall !!! It was very close but somewhat 10-20 miles to the south. The strongest winds entered with the south east flow, so with the NEern quadrant of the storm, which proves once again to be the container of the strongest inflow. I dare not to think what there is in the eyewall of that storm :shock:
Those are incredible! Thanks for sharing.

I've been pulling images off a few military sites here and they are all just amazing with this storm. Just an Incredible structure and strength!
I guess I am amazed that the surface pressures seemed so high for the winds recorded - are the high pressures in the region that strong, or was that just an instrument anomaly? :?:
Chaba has inspired me in many ways. What an incredible storm, as pointed out. Here is one of the most spectacular mesovortex features I've seen in a vis sat picture of in the eye (at least since the "starfish" pattern in Isabel last year):

Might get more pics posted soon


Thta image is incredible. What's making that backwards J-shape of cloud in the eye?
Chris, I was looking at the Saipan readings, and they show a low baro of about 29.00 inches with peak winds, and I have to believe that I am reading things wrong.
Interesting — especially considering that, if we consider a "second eyewall" in or close enough to the eye a tropical cyclone, it is sometimes said to lead to thew weakening of the system, or in others lead to intensification; I suppose such a circulation could be considered a mesovortex, or perhaps a restructuring of one.

And there's a very pretty picture of circulations like this that were photographed by a U-2 spy plane in 1958 (in typhoon Ida, I think) that's in the Life Nature Library book The Earth, if anyone has access to a copy. I wonder how strong that storm got.
Anybody have any idea of what type of wind measuring equipment they are using on Saipan and Guam? I would be very suspect of any wind readings from a cup anemometer at those speeds.

A few years ago there was a highly publicized incident where Guam claimed to have set a new record wind speed (non-tornado of course) at 236mph...breaking Mount Washington's long standing record of 231. It was later found their equipment was incorrect.

On Mount Washington we use a static pitot anemometer, we have over 100 days a year when the winds reach hurricane force.
I wonder how strong that storm got.

If you refer to IDA, I personally wrote to JTWC once to know what's in their archive..., well: 873 hpa slp (world lowest record) and 200 nautical mile per hour sustained winds near the center. Dunno if it's official or not, I just really wonder the gusts and the waves :shock: :shock: :shock: :shock: :shock:
Well, it was the largest wave ever recorded — 113 feet, I believe — that was in a typhoon in the Pacific, so it would have been very daunting, I'll bet.

It was mentioned very briefly in the news here this weekend that a typhoon, with no name or any measure of intensity given, struck Japan. Was it Chaba?
