SUBJ/PROGNOSTIC REASONING FOR TROPICAL DEPRESSION 27W (WUKONG)
WARNING NR 04//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL DEPRESSION (TD) 27W (WUKONG), LOCATED APPROXIMATELY 370
NM SOUTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-NORTHWESTWARD
AT 13 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE
IMAGERY ALONG WITH A 251126Z SSMIS 91GZ MICROWAVE IMAGE SHOWS TD 27W
CONTINUES TO DISPLAY A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION
CENTER WITH LIMITED DEEP CENTRAL CONVECTION AND A LARGE CONVERGENT
BAND OVER THE NORTHWEST QUADRANT. DVORAK INTENSITY ESTIMATES HAVE
REMAINED AT 30 KNOTS FROM BOTH PGTW AND KNES AND THE INITIAL
INTENSITY REMAINS ASSESSED AT 30 KNOTS BASED ON THESE DVORAK
ESTIMATES AS WELL AS THE CURRENT STRUCTURE OF THE SYSTEM. UPPER
LEVEL ANALYSIS AS WELL AS ANIMATED WATER VAPOR IMAGERY REVEALS
POLEWARD OUTFLOW REMAINS ROBUST BUT IS BEING OFFSET BY MODERATE (10-
20 KNOTS) VERTICAL WIND SHEAR. TD 27W IS TRACKING WEST-NORTHWESTWARD
ALONG THE SOUTHERN PERIPHERY OF THE DEEP SUBTROPICAL RIDGE (STR)
ENTRENCHED OVER THE WESTERN NORTH PACIFIC OCEAN.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TD 27W IS FORECAST TO CONTINUE TRACKING WEST-NORTHWESTWARD
THROUGH TAU 48 AS IT TRACKS TOWARD THE WESTERN EXTENT OF THE STR.
THE SYSTEM IS EXPECTED TO REMAIN AT ITS CURRENT INTENSITY AS IT
TRACKS ACROSS THE CENTRAL PHILIPPINE ISLANDS FOR THE NEXT 12 HOURS
AND THEN INTENSIFY AS IT REEMERGES IN THE NORTHERN SULU SEA AND INTO
THE SOUTH CHINA SEA. VERTICAL WIND SHEAR WILL INCREASE AFTER TAU 48
AHEAD OF A MID-LATITUDE TROUGH WHICH WILL FURTHER WEAKEN THE SYSTEM.
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT AND THE JTWC FORECAST IS
POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS WITH A MINOR
ADJUSTMENT TO OFFSET WBAR, WHICH CONTINUES TO RECURVE TD 27W
NORTHWARD THROUGH THE STR.
C. IN THE EXTENDED TAUS, TD 27W IS FORECAST TO WEAKEN DUE TO THE
FURTHER INCREASING VERTICAL WIND SHEAR ASSOCIATED WITH A FORECASTED
NORTHEASTERLY SURGE EXPECTED OVER THE SOUTH CHINA SEA. AS THE SYSTEM
WEAKENS, IT WILL TURN WEST-SOUTHWESTWARD TO SOUTHWESTWARD UNDER THE
STEERING INFLUENCE OF THE LOW-LEVEL NORTHEASTERLY FLOW AND DISSIPATE
BY TAU 96. OVERALL, HIGH CONFIDENCE REMAINS IN THE JTWC FORECAST.//

Unlike other agencies just multiplying 0.88 or 0.9 to the original table, the JMA uses the ‘Koba table’ which makes weak storms stronger, and strong storms weaker.

http://www.wmo.int/pages/prog/www/tcp/d ... alysis.pdf

Only Megi in 2010 has CI8.0 in this basin since the 21st century. I guess Wukong may only get 2.5 as its winds only reach 40 knots now. Besides, storms with T/CI2.5 in the South Hemisphere cannot be named.

looking at PAGASA's Project NOAH, it looks like the system has made landfall now with the circulation visible as it crosses Leyte Island... it seems the surface friction is tightening the circulation somewhat but that remains to be seen...

I dont think three of us need to re-post the same JTWC warning, we all have links to where to get that information.

(Promo)

Or you can go here where all three agencies are posted on the same spot

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 27W (WUKONG), LOCATED APPROXIMATELY 220 NM
SOUTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-NORTHWESTWARD AT
15 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) AND A 260005Z SSMIS IMAGE INDICATE THAT TS 27W HAS
MAINTAINED ITS WELL-ORGANIZED STRUCTURE AS IT TRACKS ACROSS THE
CENTRAL PHILIPPINES WITH DEEP CONVECTIVE BANDING WRAPPING TIGHTLY
INTO A WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). THERE IS
GOOD CONFIDENCE IN THE INITIAL POSITION BASED ON THE MSI AND SSMIS
IMAGE. THE INITIAL INTENSITY IS ASSESSED AT 35 KNOTS BASED ON DVORAK
INTENSITY ESTIMATES OF 35 KNOTS FROM BOTH RJTD AND PGTW. TS 27W IS
TRACKING WEST-NORTHWESTWARD ALONG THE SOUTHERN PERIPHERY OF THE DEEP
SUBTROPICAL RIDGE (STR) ENTRENCHED OVER THE WESTERN NORTH PACIFIC
OCEAN.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 27W IS FORECAST TO TRACK WESTWARD THROUGH TAU 36 AS IT
TRACKS TOWARD THE WESTERN EXTENT OF THE STR. THE SYSTEM IS EXPECTED
TO INTENSIFY SLIGHTLY AS IT TRACKS OVER THE SOUTH CHINA SEA DUE TO
IMPROVING POLEWARD OUTFLOW; HOWEVER, THIS PHASE IS EXPECTED TO BE
SHORT-LIVED DUE TO INCREASING VERTICAL WIND SHEAR ASSOCIATED WITH A
NORTHEAST SURGE EVENT. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT,
THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST.//

My point is we don't need to post every single warning on here with no added feedback. This is a forum, as I look above I haft to dig through JTWC information to get to the stuff Im actually looking for which is conversation on the storm. If we want JTWC info. just go to the JTWC Website.

Way off topic though and just some constructive criticism. That is all. Take it or not.

...

Putting my two cents in on the storm though, I just put together a video analysis on where it is and where its going. I hope some visiting here find it useful.

One big note, the death toll is still at 0 from what I have seen. Has anyone heard anything different? If that is the case fantastic news on the heels of Bopha.

I never saw people here re-posting warnings from the JMA. People in this forum should focus on RSMCs more.

Wukong appears to be weakening possibly due to land interaction

yes it's weakening but not that much! it still has a wide area of water with small islands to maintain its strength...

based on it's strong organization but low biased dvorak, landfall intensity is likely around 50 knots........it has since come down to 35 knots still a TS...

i think "convection-wise" it's weakening but the core structure seems intact and well-defined. i wish i could find a link of the latest MW imagery to confirm this. it seems both jtwc and nrl sites are down.
