WPAC: FUNG-WONG - Tropical Storm

[euro6208]

EURO much further west making landfall over extreme northeastern luzon, into taiwan, and passes west and northwest of Okinawa...One thing GFS and EURO agree on is that this will be a powerful typhoon fung-wong...

[somethingfunny]

I think it's time to name this one.

Hey euro, how was that earthquake? Good thing it was deep.



The Mayon Volcano is acting up too - and we have a thread in the Geology Forum, but this typhoon's rains may cause some serious complications.

It was quite strong. I was at work at the time around 4 pm. It got revised from 7.1 to 6.7 although it's nothing new

I agree...ASCAT showing a few brown barbs indicating winds between 35-40 knots...

And note that the GFS is trending west toward the Euro track. This may strike northern Luzon then head north to Taiwan vs. pass well east of Taiwan per the JTWC track. Look for JTWC to shift west with the next advisory.

[phwxenthusiast]

if the EURO and the UKMET are consistently on the left side of the envelope, that's a pretty good combination right there in terms of model verification skills. i would lean left of the consensus right now.

[dexterlabio]

I'm sorry I wasn't able to update the title, was out for a few days for a field study.


I almost thought GFS dropped this system because they showed this to stay weak in the open waters 2 days ago...look how fast things change. Hah. And now looks like 12z GFS run is more in line with the ECMWF and UKMET forecast tracks. And if we're going to believe the GFS precipitation forecast, a hefty amount of rainfall can be expected across much of Luzon from this storm's outer rainbands and the enhanced monsoon.


Also someone mentioned about the Mayon Volcano...there's lava flowing down its slope for days now and of course excessive rainfall mixing with lava and volcanic ash is something we don't want to happen here...

[Alyono]

officially a TS

However, the JMA position down near 12N is in the clouds. Does not match microwave

MASSIVE FLOOSING IN CEBU CITY RIGHT NOW. In fact, classes in public schools are cancelled.

I wonder why hasn't Fung-wong been upgraded to a tropical storm by the JTWC. This has the appearance and organization of a 40-knot tropical storm, in terms of 1-min wind speeds.

And also PAGASA insists that this will not make landfall, however the official forecast of the JMA contradicts it. I would have to agree on the JMA given the more accurate forecasts so far and that the steering winds favor more of a Northwest movement, which is different from PAGASA's forecast.

the ASCAT Pass from last night barely showed any TS-force winds. and the barbs that did might be in the heavy rain region. also, looking at the latest images, it looks like the system is still tilted and the low-level center is still elongated. in fact, i would put the center closer to 15.0N rather than the 13.0N that the JMA is saying.

either way, latest fix from PGTW is up to 2.5 so JTWC will likely upgrade this at 00z.

[xtyphooncyclonex]

Finally, the JTWC has upgraded it to TS.

And, unlike the previous storms since Halong but Genevieve, the shear is low and is sufficient for further intensification and to no surprise possibly an RI. Shear is still moderate but is decreasing fairly rapidly.

[dexterlabio]

Microwave image shows that the LLC is still displaced north of the MLC...I don't get how this could be, wind shear is relatively low near the area unlike the past few days during Kalmaegi...

It looks like all other asian weather agencies fixed the center near the MLC, while the JTWC has it near the possible LLC as the microwave image suggests. Let's see what will happen in the next few hours...

WDPN32 PGTW 180300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 16W (FUNG-WONG) WARNING
NR 03//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 16W (FUNG-WONG), LOCATED APPROXIMATELY 430 NM
EAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-NORTHWESTWARD AT 10
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS A CENTRAL DENSE OVERCAST FEATURE WITH GOOD
BANDING ON THE WESTERN AND SOUTHERN PERIPHERY WRAPPING INTO A
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). THE 172331Z AND
172120Z SSMIS MICROWAVE IMAGES CONTINUE TO SHOW INCREASED CENTRAL
DEEP CONVECTION ON THE SOUTHERN SIDE OF THE SYSTEM WITH FRAGMENTED
DEEP CONVECTIVE BANDING ALONG THE WESTERN PERIPHERY. THE CURRENT
POSITION IS BASED ON THE MSI AND AFOREMENTIONED MICROWAVE IMAGES
WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS ASSESSED AT 35 KNOTS
BASED ON DVORAK INTENSITY ESTIMATES FROM PGTW. UPPER-LEVEL ANALYSIS
INDICATES GOOD EQUATORWARD OUTFLOW AND A LOW (5-15 KNOT) VERTICAL
WIND SHEAR ENVIRONMENT, AN ENVIRONMENT FAVORABLE FOR CONTINUED
DEVELOPMENT. FUNG-WONG IS CURRENTLY TRACKING ALONG THE SOUTHWESTERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING.
B. OVER THE NEXT 24 HOURS, TS 16W WILL TRACK TO THE NORTHWEST
UNDER THE INFLUENCE OF A WEAKENING STR NORTHEAST OF THE SYSTEM. AS
THE STR BREAKS DOWN, THE SYSTEM WILL CONTINUE TO TRACK NORTHWESTWARD
AND SLOW DOWN UNDER THE SIGNIFICANTLY WEAKER STEERING ENVIRONMENT.
WHILE THERE IS THE POSSIBILITY OF RAPID INTENSIFICATION AS THE
SYSTEM TRACKS THROUGH A FAVORABLE UPPER-LEVEL ENVIRONMENT, THE
PROXIMITY OF THE TS 16W TO THE NORTHEAST COAST OF LUZON COULD
POTENTIALLY LIMIT ITS MAXIMUM WIND SPEED AT THAT TIME. MODELS ARE
IN FAIR AGREEMENT ON THE TRACK THROUGH TAU 36, WITH SIGNIFICANT
DIVERGENCE IN THE FORECAST TRACK AND SPEED AT TAU 48 AND BEYOND.
JGSM, JENS, AND GFDN FAVOR A FASTER RECURVE SCENARIO AT TAU 48
WHEREAS HWRF AND NAVGEM HAVE THE SYSTEM TRACKING TO THE NORTH UNDER
A SIGNIFICANTLY RE-BUILDING THE STR. GFS, GFS ENSEMBLE AND THE
COAMPS MODELS ARE IN THE MIDDLE WITH A WIDER RECURVE AT TAU 48 THAN
THE JAPANESE MODELS AND A TRACK THROUGH ISHIGAKI-JIMA. THE OFFICIAL
FORECAST IS IN CLOSE ALIGNMENT WITH THE MULTI-MODEL CONSENSUS
THROUGH TAU 48 AND SLIGHTLY POLEWARD THROUGH TAU 72 DUE TO THE MORE
LIKELY SCENARIO THAT THE STR WILL NOT BUILD IN AS STRONGLY AS NAVGEM
ET AL. SUGGESTS.
C. IN THE EXTENDED FORECAST, A DEEP SUBTROPICAL TROUGH, REACHING
AS FAR SOUTH AS TAIWAN, BEGINS TO ABSORB THE SYSTEM, ACCELERATING
FUNG-WONG NORTHEASTWARD AS IT CONTINUES TO BECOME EMBEDDED IN THE
BAROCLINIC BOUNDARY AND COMPLETE EXTRA-TROPICAL TRANSITION BY THE
END OF THE FORECAST PERIOD. CURRENTLY THE SYSTEM WILL TRACK TO THE
SOUTH OF KYUSHU AND SHIKOKU DUE TO THE PERSISTENT UPPER LEVEL JET,
SEEN IN ALL MODEL FIELDS, THAT IS SEMI-STATIONARY OVER SOUTH CENTRAL
JAPAN. MODEL GUIDANCE CONTINUES TO BE DIVIDED IN THESE LATER TAUS
WITH THE JAPANESE MODELS DEPICTING A RECURVE TO THE EAST OF THE
RYUKYUS AND THE GFS MODELS 16W TRACKING WEST OF THE FIRST ISLAND
CHAIN. NAVGEM AND HWRF CONTINUE THE STORM ON A NORTHWARD TRAJECTORY,
UNDER THE INFLUENCE OF A VERY STRONG BUILDING STR TO THE EAST.
JTWC'S FORECAST IS MORE ALIGNED WITH THE GFS SOLUTIONS IN THE
EXTENDED FORECAST DUE TO THE MORE LIKELY SCENARIO OF THE STR TO THE
EAST OF THE SYSTEM BUILDING IN MORE SLOWLY AND NOT AS STRONG. DUE TO
FAIR INITIAL POSITION CONFIDENCE AND SIGNIFICANT DIFFERENCES IN THE
EXTENT AND SPEED OF THE RECURVE SCENARIO, THERE IS OVERALL LOW
CONFIDENCE IN THE FORECAST.//
