WPAC: TALIM - Post Tropical

[mrbagyo]

94W
We have a New invest that i am not sure if there is even a surface circulation in it by just basing on Vis.

Unlike Invest 93W this one might hold. Please take a watch!

[euro6208]

Been following the vorticity map from EURO and it looks like it's this one that it models to become a strong typhoon passing north of Luzon.

[1900hurricane]

I've been rather sidetracked by the impressive burst in my home basin, but this one look interesting. Ensemble support is surprisingly a little low, but the operational ECMWF has taken a liking to the system. If it develops into a decent system, it may help prevent the surging NAtl ace from surpassing that of the WPac.

[Digital-TC-Chaser]

Yeah this invest may surprise,watching with interest.

AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR
11.8N 157.6E, APPROXIMATELY 430 NM NORTHEAST OF CHUUK ISLAND.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 061804Z 91GHZ
SSMIS IMAGE DEPICT FLARING CONVECTION WITH ELONGATED CURVATURE ABOUT
A LOW LEVEL CIRCULATION (LLC). A 061130Z METOP-B PARTIAL ASCAT PASS
CONFIRMS THE ELONGATED NATURE OF FLOW ABOUT THE LLC WITH 15 KNOT
WINDS. INVEST 94W IS CURRENTLY JUST INSIDE THE EDGE OF A REGION OF
LOW (5-10 KNOT) VERTICAL WIND SHEAR WITH GOOD UPPER LEVEL DIVERGENCE
AND VERY WARM (30-32 CELSIUS) SEA SURFACE TEMPERATURE. GLOBAL
DYNAMIC MODELS ARE BEGINNING TO SHOW DEVELOPMENT IN THE LAST FEW
FRAMES OF THE MODEL RUN. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 12 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1010 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

94W has medium EPS support. It's going to come down to if it can keep itself out of the TUTT, which appears like it will be rather active across the WPac.

[euro6208]

Up to MEDIUM.

THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED
NEAR 11.8N 157.6E, IS NOW LOCATED NEAR 11.8N 156.7E, APPROXIMATELY
705 NM EAST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A BROAD CIRCULATION WITH FLARING CONVECTION
BEGINNING TO WRAP IN FROM THE SOUTH. A 062307Z AMSU-B METOP-A 89GHZ
IMAGE DEPICTS AN ELONGATED CIRCULATION WITH FLARING CONVECTION. A
062306Z PARTIAL ASCAT PASS CONFIRMS THE ELONGATED NATURE OF FLOW
ABOUT THE DISTURBANCE WITH PRIMARILY 15 KNOT WINDS IN THE SOUTHEAST
QUADRANT, BUT SHOWING SOME 20 KNOT WINDS AS WELL. THE DISTURBANCE IS
CURRENTLY LOCATED IN A REGION OF LOW (5-10 KNOT) VERTICAL WIND SHEAR
WITH GOOD EQUATORWARD OUTFLOW AND VERY WARM (30-32 CELSIUS) SEA
SURFACE TEMPERATURES. GLOBAL DYNAMIC MODELS ARE IN AGREEMENT THAT
THE DISTURBANCE WILL TRACK TO THE WEST-NORTHWEST WITH THE TIMING OF
CONSOLIDATION RANGING FROM 48-108 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.

Next name in JMA's naming list is "TALIM" which literally means "sharp" in the Tagalog language.




ECMWF is still very persistent in developing 94W into a formidable typhoon - latest 00z run has it plowing into Taiwan on the 16th of Sept.
CMC joins Euro in the typhoon bandwagon but recurves it out to sea with possible impact on Japan.
JMA - only shows a closed low in th Philippine Sea at the end of the run.

GFS and NAVGEM are still not enthused with 94W.

EDIT: The next name on the list is TALIM not Talas - the Tagalog meaning remains the same since the two words are synonymous.

[Digital-TC-Chaser]

Ogranising low with decent rotation.

[mrbagyo]

94W getting some love from HWRF - 06z run strengthens it to cat 4 in the Philippine Sea.

[mrbagyo]

Already a Tropical Depression per JMA but not expecting it to develop into a TC

TROPICAL DEPRESSION 1010 HPA AT 12N 154E WEST SLOWLY.

[doomhaMwx]

HWRF also hinting that 94W has a potential to become a powerful Typhoon...

[mrbagyo]

JMA now expects 94W to remain a TD for the next 48 hours - slow organization

At 1800 UTC, 07 September 2017, INVEST (WP94) was located in the Northwest Pacific basin at 10.9°N and 153.7°E. The current intensity was 20 kt and the center was moving at 12 kt at a bearing of 270 degrees. The minimum central pressure was 1006 mb.

NWS

Divergence associated with an upper-level trough is the main
trigger of the activity this morning. There could also be a
surface trough involved, this is more difficult to pick out.
Refined the forecast some based on radar and satellite, the basic
philosophy is unchanged though. Showers are now scattered this
morning then isolated as this band pushes through. After midnight
they then increase again to occasional as the disturbance
approaches. The winds should mainly be to the north of the center.
They will not be that high at this point, maybe 25 knots or so.
Used nearshore wave preduction system to get wave grids more
consistent with the wind fields. After Sunday, the weather should
dry out a bit and the forecast is largely unchanged.

&&

.Marine...
Generally, combined seas will be 2 to 4 feet through the middle of
next week for the Marianas waters. The exception will be in the
Rota waters northward, where, for Saturday and Saturday night, the
waves could briefly rise to between 4 and 6 feet. This will occur
in response to a passing tropical disturbance. Winds will be
mainly to the north of the center and could reach as high as 25
knots. Especially if it is near this high end, it could require a
small craft advisory for winds.

&&

.Tropical systems...
The disturbance to our east is being monitored by the Joint
Typhoon Warning Center. It currently has a medium chance of
becoming a tropical depression in the next 24 hours. This is
roughly the same time frame as it will be passing through the
Marianas, so it should be clear of the forecast zones before it
intensifies significantly past this.

EURO peaks Talas at 931 mb but weakens it to 951 mb as it parallels the coast of Taiwan.
