Re: WPAC: 11W- Tropical Depression
According to pagasa, it will enhance the SW monsoon over the weekend(it won't make a landfall in the philippines)....
Should start heading northwards soon based on jma and jtwc tracks...

Back to the very strong westerly turn, and a much stronger system on the 00z. A much more agressive run overall thats for sure.

Yeah! I think it's likely Muifa will make landfall somewhere down the road. Interests from Taiwan to Japan and in between will need to watch this one closely! Indeed JMA 5 day track takes this pretty close to Ryukus.

Yep needs to be watched very closely, the models seem to be all over the place. GFS bends back west but much further north, close call with SW Japan.

seems to me it's moving more west than though, it's now inside the PAR.. i hope it spares the Philippines...
Meari (Falcon) went near Taiwan but it brought significant rainfall across Luzon, and also caused ruckus on the infamous Marikina River when it almost spilled off. Induced monsoonal flow appears to be the problem in the Philippines, at least. By the way, the latest ECM track is similar to the track of TY Fanapi last year. Also a Taiwan-hitting typhoon.

The track of Muifa is pretty unusual if the ECM is right, for it to go nearly straight north, even NNE and then bend back that far west would be a most interesting track!
Looks like its finally strengthening...

Re: WPAC: Muifa- Tropical Storm
Very unrealistic at this time for the storm to head on straight into the ridge.
I dont want to sound alarmist but we might need to take heed as well.

Re: WPAC: Muifa- Tropical Storm
Muifa? Muifa?! Aw come on! If we're going to get hit with a storm, can't we have a big, bad name? That name is destined to be the laughingstock of Okinawa if it hits us. I can hear it now...
Yeah, this is one to watch...projected track has shifted all over the place!

Re: WPAC: Muifa- Tropical Storm
^Yes, forming that large CDO again. I really think the period of quick strengthening is starting.
Also seeing a south of west jog for the past few hours, and bit slowing down... http://www.goes.noaa.gov/sohemi/sohemiloops/vsmtsatw.html Just saying, Songda last May did somewhat of a west to wsw bend, slowed down then began turning more northwards. Nock-ten also did quite the same thing, it went west to wsw then it started to move northwestwards. I don't know if what I'm thinking is right but it seems it signifies that a more northerly movement is next? What do you think?

Have to agree with you. Though we just need to make sure that the STR to the north must weaken or retreat on time so that things would be more proper for us (but not for Okinawa I think, sorry folks for sounding selfish! ) Just kidding.
Seriously, if the westward movement becomes continuous and quick, Taiwan and Philippines must also be ready for the worst.

REMARKS:
280900Z POSITION NEAR 12.0N 134.7E.
TROPICAL STORM (TS) 11W (MUIFA), LOCATED APPROXIMATELY 590 NM WEST
OF ANDERSEN AFB, GUAM, HAS TRACKED JUST SOUTH OF WESTWARD OVER THE
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS THE
SYSTEM HAS EXPANDED AS CONVECTIVE TOPS DEEPENED. INITIAL POSITION
AND INTENSITY ARE BASED ON DVORAK FIXES FROM PGTW AND RJTD. UPPER
LEVEL ANALYSIS INDICATES THE STORM IS 10 DEGREES SOUTHEAST OF AN
ANTICYCLONE THAT IS CAUSING SUBSIDENCE ALONG THE NORTHEAST QUADRANT.
HOWEVER, A RIDGE TO THE SOUTH IS PROVIDING EFFICIENT EQUATORWARD
OUTFLOW. THESE DYNAMICS ARE EVIDENT ON ANIMATED WATER VAPOR IMAGERY.
TS 11W, CURRENTLY UNDER MODERATE (15-20 KT) NORTHEASTERLY VERTICAL
WIND SHEAR (VWS), IS TRACKING ALONG THE SOUTHERN BOUNDARY OF A LOW-
TO MID-LEVEL SUBTROPICAL RIDGE ANCHORED JUST SOUTHEAST OF KYUSHU,
JAPAN. THIS RIDGE IS BEGINNING TO RECEDE AND WILL CAUSE THE SYSTEM
TO TURN SHARPLY POLEWARD WITHIN THE NEXT 12 HOURS. THIS POLEWARD
MOTION WILL DIMINISH THE SUBSIDENT EFFECT OF THE ANTICYCLONE TO THE
NORTHWEST AND ALSO REDUCE THE VWS, FAVORING GRADUAL INTENSIFICATION
OF THE SYSTEM. AFTER TAU 36, A NEAR EQUATORIAL RIDGE TO THE EAST
WILL ASSUME STEERING AND TUG THE CYCLONE SLIGHTLY RIGHT OF POLEWARD.
AS THE SYSTEM GAINS LATITUDE, THE ENVIRONMENTAL CONDITIONS WILL
REMAIN CONDUCIVE FOR FURTHER DEVELOPMENT. TS 11W IS EXPECTED TO
INTENSIFY INTO A MODERATE TYPHOON BY TAU 96 WHEN A BUILDING STR EAST
OF HONSHU JAPAN ASSUMES STEERING AND PUSHES 11W LEFT OF POLEWARD.
THE AVAILABLE NUMERICAL GUIDANCE IS IN LOOSE AGREEMENT AND FANS OUT
TO A 20 DEGREE SPREAD. ALL, HOWEVER, DEPICT AN S-SHAPE TRACK PATTERN
MOLDED BY THE THREE STEERING INFLUENCES DESCRIBED ABOVE. THERE IS
ONE EXCEPTION: WBAR MAINTAINS A PROLONGED WESTWARD TRAJECTORY BEFORE
TURNING POLEWARD AT TAU 96. THIS TRACK FORECAST IS SLIGHTLY LEFT OF
CONSENSUS AT THE BEGINING OF THE FORECAST PERIOD TO ACCOUNT FOR THE
PERSISTENT WESTWARD STORM MOTION. NEXT WARNINGS AT 281500Z, 282100Z,
290300Z AND 290900Z. REFER TO TROPICAL STORM 10W (NOCK-TEN) WARNINGS
(WTPN31 PGTW) FOR SIX-HOURLY UPDATES.//
