There seems to be model support for 94W but it's in the long range and its development may be affected based on how Trami tracks

Good agreement between EURO and GFS on this developing.

I don't think imo 94W is what they are developing the model storm^ they are developing comes way below latitude compared to the location of 94W, unless 94W would be relocated way below south of its current location
Here is latest BT
94W INVEST 180923 1800 10.5N 158.1E WPAC 15 1010
But the GFS and other models start the model storm development around 4-5N

Looks like theres a glitch. All storms in the WPAC disappeared on BT and the Navy site.

I still don't believe this is the one models are developing, models start to develop it below 5N, unless 94W gets relocated even further south, or around below 5N

Seems like JTWC sees this develop but see the highlighted statement

(2) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 7.9N
157.7E, APPROXIMATELY 70 NM NORTH-NORTHWEST OF POHNPEI, FEDERATED
STATES OF MICRONESIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A LARGE, EXPOSED LOW-LEVEL CIRCULATION WITH PERSISTENT YET
DISORGANIZED DEEP CONVECTION FLARING OVER THE SOUTHERN PERIPHERY. A
250245Z AMSR2 89GHZ IMAGE INDICATES A POORLY DEFINED LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH VERY WEAK CONVECTIVE STRUCTURE.
SURFACE OBSERVATIONS FROM POHNPEI REVEAL SOUTHERLY WINDS AT 5 KNOTS
AND SLP NEAR 1006MB. A 242234Z ASCAT IMAGE SHOWS AN ELONGATED,
DEFINED CIRCULATION WITH 20-25 KNOT CONVERGENT WESTERLY WINDS OVER
THE SOUTHERN SEMICIRCLE AND 10-15 KNOT EASTERLY WINDS OVER THE
NORTHERN SEMICIRCLE. UPPER-LEVEL ANALYSIS DEPICTS A MARGINAL
ENVIRONMENT WITH A BROAD INVERTED TROUGH AND CONVERGENT FLOW OVER
THE SYSTEM OFFSET BY WEAK DIFFLUENCE. GLOBAL MODELS INDICATE A
DISTINCT LLCC WILL DEVELOP AND CONSOLIDATE WITHIN THE SOUTHERN
PERIPHERY OF THIS LARGE CIRCULATION
OVER THE NEXT 1-2 DAYS WITH
SIGNIFICANT DEVELOPMENT AS THE SYSTEM TRACKS NORTHWESTWARD TOWARD
GUAM AFTER DAY TWO. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

***HIGH SURF ADVY FOR YAP, KOROR, KOSRAE***

The circulation is nearly stationary SSE of Pohnpei, which has been expected. Models show it moving WNW starting Thursday. Still some uncertainty on if the system will begin that WNW motion just yet, once it does, it'll be 3-4 days to get near the Marianas and we'll quickly see models getting in better agreement on the strength of storm: whether a weak circulation with much rain or a tropical storm.

For those of you keeping track of the number of tropical cyclones, JTWC has issued a TCFA well north of the region near 25N154E. This circulation could become TD 29W by Thursday. It will not affect our region as it remains weak, moves NW...N...and eventually NE over the north Pacific.
