REASONING NO. 3 FOR TS 1105 MEARI (1105)
1.GENERAL COMMENTS
REASONING OF PROGNOSIS THIS TIME IS SIMILAR TO PREVIOUS ONE.
POSITION FORECAST IS MAINLY BASED ON NWP AND PERSISTENCY.
2.SYNOPTIC SITUATION
NOTHING PARTICULAR TO EXPLAIN.

4.INTENSITY FORECAST
TS WILL BE GRADED UP TO STS WITHIN 24 HOURS.
TS WILL DEVELOP BECAUSE CYCLONE WILL STAY IN HIGH SST AREA.
FI-NUMBER WILL BE 3.5 AFTER 24 HOURS.=

SO should we look into the North and NW movement the last few hours or yo uthink it will go back NW to the original track

Wait where is the center relocated by JTWC again? Somewhere east? Well I think that the center is actually the exposed area near the deep convection. Maybe the convection still wrapping around the center.

And also I don't know which agency should I rely on. They all have different location estimates except for some that are slightly the same.

This is very rare that there are so many different forecasted tracks....I wouldnt be suprised if they put Okinawa in TCCOR 3 is a percaution as they do fro mtime to time if it could be close enough...but I wouldnt expect that call until tomorrow..the reasoning is the last few hours it has taken a more north north west vise just a north west track..something that has to be watched but that can change again

I think even though Meari tracks somewhere near Taiwan, Okinawa would experience stormy weather with that huge circulation of the storm. So I believe putting Okinawa under a storm warning is right.

They said if it where to stay on track (which it looks to be to th eeats of tha tnow) we would see 35-50 knot winds) if it continues the track and doesnt go back northwest im sure tha twill change alot

Storming, quite difficult to tell in this system that has failed thus far to fully consolidate and therefore is vulnerable to changes in track just from relocation. It's pretty easy to say recurvature around the subtropical ridge, but the devil is always in the detail, and with the system having this big a windfield, any deviation eastward would put Okinawa in danger for higher winds. Here's the steering flow (very similar at all levels):

Here is JTWC's discussion:
WDPN32 PGTW 230300
MSGID/GENADMIN/NAVMARFCSTCEN PEARL HARBOR HI/JTWC//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 07W (MEARI)//
/WARNING NR 06//
RMKS/
1. FOR METEOROLOGISTS.
2. 12 HOUR SUMMARY AND ANALYSIS.
A. TROPICAL STORM (TS) 07W (MEARI), LOCATED APPROXIMATELY 410 NM
EAST OF MANILA, PHILIPPINES, HAS TRACKED NORTH-NORTHWESTWARD AT
07 KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 222114Z SSMIS IMAGE.
THE LOW LEVEL CIRCULATION OF TS 07W REMAINS ELONGATED, WITH MULTIPLE
SMALL-SCALE VORTICES DEVELOPING AND ROTATING AROUND THE CENTER. DEEP
CONVECTION CONTINUES TO CYCLICALLY DEVELOP AND WANE NEAR THESE
VORTICES, THE MOST PROMINENT OF WHICH NOW LIES TO THE NORTH OF THE
BROADER CIRCULATION CENTER. THE CURRENT INTENSITY OF 40 KNOTS IS
CONSISTENT WITH RECENT DVORAK T-NUMBER ESTIMATES AND CONVECTIVE
STRUCTURE EVIDENT IN RECENT MICROWAVE SATELLITE IMAGERY. TS 07W HAS
TRACKED NORTHWESTWARD OVER THE PAST 12 HOURS UNDER THE INFLUENCE OF
A SUBTROPICAL STEERING RIDGE TO THE NORTHEAST.
3. FORECAST REASONING.
A. THE FORECAST TRACK HAS BEEN SHIFTED EASTWARD SINCE THE
PREVIOUS ISSUANCE OF THE PROGNOSTIC REASONING MESSAGE. TS 07W IS NOW
EXPECTED TO UNDERGO EXTRATROPICAL TRANSITION VICE DISSIPATION,
ALTHOUGH THE SYSTEM WILL WEAKEN DURING THE TRANSITION.
B. TS 07W IS EXPECTED TO ROUND THE AXIS OF THE STEERING RIDGE
AHEAD OF AN APPROACHING MID-LATITUDE TROUGH DURING THE FORECAST
PERIOD. AS THE SYSTEM MOVES POLEWARD, IT WILL ENCOUNTER INCREASING
VERTICAL WIND SHEAR AND SUBSIDENCE ALOFT, INTRODUCED BY AN UPPER
LEVEL LOW TO THE NORTH, AND THE LOW LEVEL CIRCULATION WILL STRUGGLE
TO CONSOLIDATE. HOWEVER, EQUATORWARD OUTFLOW ALOFT IS EXPECTED TO
REMAIN STRONG AND THE SYSTEM WILL PASS OVER VERY WARM WATER FOR AT
LEAST THE NEXT 48 HOURS. TS 07W SHOULD SLOWLY INTENSIFY UNDER THESE
COMPETING INFLUENCES BEFORE PASSING OVER COOLER WATER AND
ENCOUNTERING STRONGER VERTICAL WIND SHEAR AHEAD OF AN APPROACHING
MID-LATITUDE TROUGH BY TAU 72. THE CURRENT TRACK FORECAST IS IN GOOD
AGREEMENT WITH THE MAJORITY OF THE NUMERICAL MODEL GUIDANCE IN THE
NEAR TO MEDIUM TERM, INCLUDING THE LATEST ECMWF, JGSM, UKMET, AND
GFS RUNS. THE NOGAPS AND GFDN MODELS CONTINUE TO DEPICT A TRACK A
BIT FARTHER TO THE EAST, A SCENARIO DEEMED UNLIKELY GIVEN THE
MAJORITY OF THE MODEL GUIDANCE AND CURRENT SYNOPTIC REASONING.
HOWEVER, INTERACTION BETWEEN TS 07W AND THE UPPER LEVEL LOW TO THE
NORTH COULD RESULT IN A SLIGHT EASTWARD DEFLECTION OF THE TRACK,
THOUGH ANY INTERACTION BETWEEN THE CIRCULATIONS SHOULD BE LIMITED IF
TS 07W REMAINS A WEAK AND RELATIVELY SHALLOW SYSTEM AS FORECAST.
C. TS 07W IS EXPECTED TO ACCLERATE INTO THE MID-LATITUDE FLOW
PATTERN AND UNDERGO EXTRATROPICAL TRANSITION IN THE EXTENDED
FORECAST PERIOD. THE STEERING RIDGE WILL AMPLIFY AHEAD OF A
DEVELOPING MID-LATITUDE TROUGH DURING THIS PERIOD, RESULTING IN A
MERIDIONAL STEERING PATTERN. INCREASING VERTICAL WIND SHEAR AND
PASSAGE OVER COOLER WATER WILL INDUCE PRONOUNCED WEAKENING DURING
THIS TRANSITION PERIOD.//

ASCAT continually misses the center but does show the broad windfield:

Interesting that KNES and PGTW satellite bulletins keep following a northern vortex. Will have to wait and see if Meari can consolidate around a particular center.

latest from PAGASA(it's interesting to note that PAGASA mentioned a low pressure area northeast of catanduanes)
Image

Residents in low lying and mountainous areas under signal # 1 are alerted against possible flashfloods and landslides.

TS "FALCON" is expected to enhance the Southwest Monsoon and will bring rains over Southern Luzon, Visayas and Mindanao.

Meanwhile, A Low Pressure Area (LPA) was estimated at 550 km Northeast Virac Catanduanes

Gale Warning is issued over the Eastern seaboard of the country and the Western seaboard of Luzon and of Visayas.

The public and the disaster coordinating councils concerned are advised to take appropriate actions and watch for the next bulletin to be issued at 5 PM today and the hourly updates.

To follow off of what supercane mentioned earlier I want to mention the placement of an upper level trough on the 25-26th as 07W moves towards the Ryuku Islands. I'm pretty confident (and just my thoughts) this will go extra-tropical, thus if does move well east of Okinawa it will form up some gradient induced winds over the island due to a (cold front) forming. Even after the system is well NW of the islands I think there is the potential for high winds and thunderstorms.

Once again my thoughts..

We're experiencing heavy rain and moderate to strong winds...I'm guessing that this will be the same thing that okinawa will experience once the storm moves near there....

My office is in the 10th floor and I have been hearing "whistling" sounds the past couple of hours because of the wind....It's actually quite creepy...

What a strange system, looks like its struggling to pull itself together and thus has gone down the massive route instead...
