JMA has it moving north the entire forecast period, not gaining or losing a single degree in longitude!


Yeah and a typhoon within 72 hours too. I'm placing my bets on Nanmadol being the dominant storm. My reason is primarily because it's is consolidating more rapidly than the Guam blob and I feel the models are more or less hopeless right now regarding track let alone intensity due to this potential DCI / Fuijiwhara.

Agencies are all over the place right now too. HKO have already busted because they forecast it to remain a depression for the next 3 days. JTWC forecast this to start flying off NE in a few days and JMA more or less dead north over next 5 days. CWB are favouring the JTWC track too. I don't envy the agencies!

Just my amateur opinion!

This may sound ignorant, but please o please someone explain to me how to pronounce this.

11th named storm of the season is Nanmadol.

Nanmadol; submitted by Federated States of Micronesia; named after Nan Madol ruin in Pohnpei (Ponape), FSM.

Nan Madol is a US National Historic Landmark and is on the National Register of Historic Places.

Based on this information, my expectation is that "Nanmadol" is to be pronounced as spelled, NAN-ma-doll.

The last Nanmadol I can remember is in 2004, which became a very large Cat4 supertyphoon.

Haha I think there will be a cut in the attention for Irene as many surprisingly began to think that it will be a fish. :roll: :lol: My attention have never been divided fpr some time ATL until that Irene came.

True that, they have an interesting storm to track down there but I'm pretty sure we'll have another storm nice to track in the coming days. :lol:

11th named storm of the season is Nanmadol.

HKO has a page with audio clips with storm name pronunciations (requires Real Player). Nanmadol's link is http://www.hko.gov.hk/informtc/sound/micronesia/nanmadol.rm. To my ear, it sounds like NAN-ma-DOL. I do not see any information on the site where they got these pronunciations, but it's a start.

WARNING NR 04//
RMKS/
1. FOR METEOROLOGISTS.
2. 12 HOUR SUMMARY AND ANALYSIS.
A. TROPICAL STORM (TS) 14W, LOCATED APPROXIMATELY 625 NM SOUTH OF
KADENA AB, OKINAWA, HAS TRACKED NORTHWARD AT 03 KNOTS OVER THE PAST
SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY INDICATES THAT TS 14W
HAS CONTINUED TO CONSOLIDATE WITH IMPROVED, TIGHTER CONVECTIVE
BANDING WRAPPING FROM THE NORTH QUADRANT INTO THE SOUTHEAST QUADRANT
OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). CONSEQUENTLY, DVORAK
ESTIMATES HAVE INCREASED TO 45 KNOTS FROM BOTH KNES AND PGTW AND THE
CURRENT INTENSITY IS NOW ASSESSED AT 45 KNOTS. THERE IS GOOD
CONFIDENCE IN THE CURRENT POSITION AND MOTION BASED ON A 231056Z
TRMM 37H IMAGE SHOWING A WELL-DEFINED LLCC. ANIMATED WATER VAPOR
IMAGERY INDICATES A POLEWARD OUTFLOW CHANNEL INTO A TUTT CELL
LOCATED JUST EAST OF OKINAWA. EQUATORWARD OUTFLOW IS FAIR WITH
STRONG DIFFLUENCE SOUTHWEST OF THE LLCC.
3. FORECAST REASONING
A. NO SIGNIFICANT CHANGE IN FORECAST PHILOSOPHY.
B. AVAILABLE MODEL GUIDANCE IS IN POOR AGREEMENT AND HAS ALSO
EXHIBITED SIGNIFICANT SHIFTS IN TRACK OVER THE PAST FEW RUNS. NOGAPS
HAS SHIFTED FROM AN EASTWARD TRACK TO A NORTHWESTWARD TRACK TOWARD
TAIWAN. GFDN HAS SIMILARLY SHIFTED FROM AN EASTWARD TRACK AND IS NOW
INDICATING A WESTWARD THEN NORTHWARD TRACK. THE JTWC FORECAST LEANS
MORE TOWARD THE ECMWF, GFS, UKMO AND JGSM SOLUTIONS WHICH HAVE
REMAINED FAIRLY CONSISTENT WITH A SLOW NORTHWARD TO NORTHEASTWARD
TRACK THROUGH TAU 72. THIS TRACK IS ALSO MORE CONSISTENT WITH THE
TYPICAL TRACKS ASSOCIATED WITH A GYRE PATTERN. TS 14W IS FORECAST TO
CONTINUE INTENSIFYING AND SHOULD REACH TYPHOON STRENGTH BY TAU
72.
C. IN THE EXTENDED TAUS, THERE REMAINS A HIGH DEGREE OF
UNCERTAINTY DUE TO THE COMPLEX GYRE PATTERN AND THE FORECAST
FUJIWARA BETWEEN 14W AND ANOTHER SYSTEM DEVELOPING NORTHWEST OF
GUAM. THERE IS A VERY LARGE SPREAD IN THE MODEL GUIDANCE AND THIS
FORECAST IS POSITIONED RIGHT OF THE CONSENSUS, FAVORING THE ECMWF,
UKMO, JGSM, AND GFS SOLUTIONS.//

Agree that it would be nice if the moderators could update the thread title to Tropical Storm Nanmadol; otherwise, will have to wait for Storming to do it later.

JWTC steadily becoming more and more agressive with thier forecasts, looks more reasonable then it did before to be fair...when they kept it as a 50kts TS!

JMA's forecast there is like.. UMM IDK... ???

Honestly the most inconclusive storm here. This combined with the interaction with the 97W is going to be interesting. All forecasting skills to be put to the test.

As for me I just told the people I work for here that when the storms meet it will be like a star blowing up sending a tsunami across the pacific. Now time to sit back and see how many people took me seriously.

I know I'm joking about this one, but right now looking at the model guidance out for the 27th and beyond, I can't help but just going oooo (curse word).

Lets hope the model back off of on it and come in to a better scenario, I think this will happen to be honest.

Exactly, this is defiantly a brain teaser with several possibilities here all the cards come in to play.

as i said before, anywhere from Taiwan to Kyushu/Shikoku is still on target and looks like the latest model package (12z) is downplaying the DCI between 97W... let's see if that will start a trend--it could very well head towards Taiwan for all we know..

anyway, latest MI still showing a somewhat lopsided structure... :roll: this thing had an amzing diurnal blow up overnight though

Hmmm interesting little warm spot in the middle of the system, possibly developing an eye?

if it is, then i say the system is not vertically stacked just yet... the LLCC is still located about northeast of that warm spot based on 37Ghz; but it is intensifying that's for sure

Yeah does look like an eye, that better image sorta backs up the orginal idea that it is an eye that is forming.
