WPAC: MELOR - Post-Tropical

[euro6208]

The Philippines is probrably the only country in the world, unfortunately living in the most active basin, to experience multiple landfalls and from strengthening ones due to it's unique archipelago...

Typhoon Melor (Nona) Weakening After Five Landfalls in Philippines; Flooding Rains Continue (FORECAST)



Weather.com

I don't know but according to that map, I counted more than 5 landfalls...

[euro6208]

Melor's trek over the Philippines isn't done...

While all models weaken this some more but still bring a strong disturbance into the NIO, GFS is persistent...

00Z is even stronger...It brings a strong cyclone to the Andaman islands with a possible cyclone for Malaysia.

Possible Cat 5 for the Andaman Islands recurving to south Asia...

[wxman57]

Looks like Melor may have dissipated north of Palawan. I don't see much of any LLC, and the mid-level center is racing northward across northern Luzon.

SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 28W (MELOR)
/WARNING NR 21//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM 28W (MELOR), LOCATED APPROXIMATELY 125 NM NORTHWEST
OF MANILA, PHILIPPINES, HAS TRACKED NORTHWARD AT 07 KNOTS OVER THE
PAST SIX HOURS. THERE IS LOW CONFIDENCE IN THE POSITIONING OF THE LOW
LEVEL CIRCULATION CENTER (LLCC) FOR TS 28W AS STRONG (30 TO 40 KNOTS)
OF VERTICAL WIND SHEAR (VWS) CONTINUES TO DECOUPLE THE LOW AND UPPER
LEVEL FEATURES. BASED ON THE POSITIONING FIXES FROM PGTW AND RJTD
ALONG WITH ENHANCED INFRARED SATELLITE IMAGERY, THE LLCC HAS TRACKED
NORTHWARD, AND APPEARS TO BE SLOWING SLIGHTLY OVER THE PAST SIX
HOURS. INTENSITY HAS BEEN DECREASING EQUALLY AS RAPIDLY, WITH DVORAK
ESTIMATES RANGING FROM 45 TO 55 KNOTS. THE CURRENT INTENSITY OF 50
KNOTS IS A BLEND OF THESE AVAILABLE ESTIMATES. TS 28W IS STARTING TO
SLOW AS IT APPROACHES THE SOUTHERN EXTENT OF THE NORTHEASTERLY COLD
SURGE BOUNDARY, AND IS BEGINNING TO TRANSITION TO A NEW STEERING
REGIME.
3. FORECAST REASONING.
A. THERE IS NO SIGNIFICANT CHANGE IN THE FORECAST PHILOSOPHY FROM
THE PREVIOUS PROGNOSTIC REASONING BULLETIN.
B. TS MELOR WILL START TO SLOW AS THE LLCC BECOMES DECOUPLED FROM
THE CONVECTION UNDER THE INFLUENCE OF THE STRONG VWS. THE LLCC WILL
SUBSEQUENTLY START TRACKING TO THE SOUTHWEST UNDER THE INFLUENCE OF
THE NORTHEASTERLY COLD SURGE WITHIN THE SOUTH CHINA SEA. HIGH VWS
VALUES AND ENTRAINMENT OF COOLER, DRIER AIR WILL CONTINUE TO RAPIDLY
WEAKEN TS 28W AS IT BECOMES FULLY EMBEDDED WITHIN THE COLD SURGE.
THE COMPLETE DISSIPATION OF THE SYSTEM IS EXPECTED BY TAU 48.
NUMERICAL MODELS ARE IN FAIR AGREEMENT REGARDING THE ANTICIPATED
TRACK, BUT NONE HAVE ACCOUNTED FOR THE RECENT TURN TO THE NORTH IN
THE PAST 12 HOURS. GIVEN THE UNCERTAINTY IN TIMING FOR THE SOUTH-
WESTWARD TURN AND THE POOR CONFIDENCE IN POSITIONING FOR THE LLCC,
THE FORECAST TRACK HAS BEEN PLACED CLOSE TO THE MULTI-MODEL
CONSENSUS, WITH LOW CONFIDENCE.//

[1900hurricane]

ASCAT is not very convincing that a low level center still exists, unless maybe it's near the mouth of Manilla bay over Luzon.

[1900hurricane]

While it may incorporate the remnants of Melor and 97W, it looks to me that the modeled Gulf of Thailand/Bay of Bengal system is a separate entity.

[wxman57]

Yeah, no circulation on ASCAT and certainly not a 50kt TS. It's a remnant low. NE monsoon winds of 25-35kts dominate the S. China Sea.

[Alyono]

I'm killing this off in a few minutes. My patience has ran out with this one

RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 28W (MELOR), LOCATED APPROXIMATELY 105 NM
WEST-SOUTHWEST OF MANILA, PHILIPPINES, HAS TRACKED SOUTHWESTWARD AT
03 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY SHOWS DEEP CONVECTION SHEARING TO THE NORTHEAST
DUE TO PERSISTENT 45 TO 50 KNOT SOUTHWESTERLY VERTICAL WIND SHEAR
(VWS). BASED ON RECENT MULTISPECTRAL SATELLITE IMAGERY AND A 161348Z
ASCAT PASS, THE STRONG NORTHEASTERLY COLD SURGE EVENT HAD SET IN
THROUGHOUT THE SOUTH CHINA SEA. THE INITIAL POSITION IS PLACED WITH
LOW CONFIDENCE BASED ON EXTRAPOLATION FROM A 160348Z AMSR-2 89GHZ
MICROWAVE IMAGE WHICH SHOWED AN IN-TACT LOW LEVEL CIRCULATION
CENTER. THE CURRENT INTENSITY IS BASED ON THE RAPID WEAKENING OF THE
SYSTEM DUE TO THE HIGH VWS AND IS SUPPORTED BY DECREASING DVORAK
INTENSITY ESTIMATES FROM ALL AGENCIES. THE SYSTEM IS TRACKING
EQUATORWARD WITH THE NORTHEASTERLY SURGE EVENT.
3. FORECAST REASONING.
A. THE STORM WAS RELOCATED BASED ON EVIDENCE IN MICROWAVE IMAGERY
THAT THE SYSTEM DECREASED FORWARD SPEED AND TURNED SOUTH WITH THE
NORTHEASTERLY SURGE EVENT AFTER PASSING THROUGH THE PHILIPPINES.
HOWEVER, THERE IS NO SIGNIFICANT CHANGE IN THE FORECAST PHILOSOPHY
FROM THE PREVIOUS PROGNOSTIC REASONING BULLETIN.
B. TS MELOR WILL CONTINUE TO DETERIORATE DUE TO THE HIGH VWS AND
THE COLD STABLE AIR PROVIDED BY THE SURGE EVENT. THE SYSTEM WILL
CONTINUE TO TRACK SOUTHWESTWARD AND FULLY DISSIPATE BY THE END OF
THE FORECAST PERIOD OR POSSIBLY SOONER. DYNAMIC MODEL GUIDANCE IS IN
TIGHT AGREEMENT THROUGHOUT THE FORECAST PERIOD; HOWEVER, THE POOR
CONFIDENCE IN THE INITIAL POSITION LEADS TO LOW CONFIDENCE IN THE
JTWC FORECAST.//

REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 170000Z
IS 8 FEET. REFER TO TROPICAL DEPRESSION 29W (TWENTYNINE) WARNINGS

No way Melor only peaked at 125 knots with this satellite presentation of a pinhole east of the Philippines and before making landfall over Mindoro...
