JMA forecasting a TD in 48 hours... still looks rather elongated to me although the LLCC seems a bit better this afternoon...

No, it’s already a tropical depression.

Re: WPAC: INVEST 94W
no one seems to be interested with 94W.
not surprising at all since it's very disorganized at the moment..
BUT some models have already picked this up on their runs..or possibly another invest?idk but here it is..
latest Multi-model ensemble
forecast is that it would be quite weak..could only be a strong LPA or weak depression..
of course, this may change in the coming days but might as well be aware..
and btw..94W is back to TD status by JMA..

Re: WPAC: INVEST 94W
AN AREA OF CONVECTION HAS PERSISTED NEAR 2.7N 127.9E,
APPROXIMATELY 435 NM SOUTHEAST OF ZAMBOANGA, PHILIPPINES. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN EXPOSED LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH ISOLATED CONVECTION FLARING OVER THE
LLCC. DESPITE THE LACK OF DEEP CONVECTIVE BANDING, A 090906Z SSMIS
37 GHZ IMAGE DEPICTS SHALLOW CONVECTIVE BANDING WRAPPING INTO A
DEFINED CENTER. RECENT SCATTEROMETER DATA DEPICTS A PERSISTENT AND
QUASI-STATIONARY CIRCULATION WITH 15 TO 20 KNOT WINDS. UPPER-LEVEL
ANALYSIS INDICATES THAT THE LLCC IS LOCATED WITHIN AN UNFAVORABLE
ENVIRONMENT WITH MODERATE TO STRONG (20 TO 30 KNOTS) EASTERLY
VERTICAL WIND SHEAR AND STRONG DIFFLUENCE ALOFT. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. DUE TO THE UNFAVORABLE
ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

Re: WPAC: INVEST 94W
no model support? The NOGAPS and Canadian models were already hinting possible formation around that area for some days now. GFS was picking it up but as a disorganized low pressure system....though the recent model runs now seem to show possibility of a well-organized TC, possibly turning NW then north towards an approaching mid-latitude trough. Euro shows nothing.
Maybe I can wait for it to actually happen then I'll be looking at the Euro model then to see where it can possibly go.

it is very disorganized at the moment. there is no well defined LLCC and dvorak showing nothing...maybe this has a better chance once it passes luzon and heads out to sea...

it seems like JMA upgrades every area to a TD regardless of how it looks (disorganized). without no reasoning in their warning, we will never know...We see a TD in the map and a simple text...

Re: WPAC: INVEST 94W
strong shear is inhibiting development right now...but it does have more convection but still very disorganized...
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 2.7N 127.9E,
IS NOW LOCATED NEAR 3.9N 129.3E, APPROXIMATELY 465 NM EAST-SOUTHEAST
OF ZAMBOANGA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A BROAD, PARTLY EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH ISOLATED AND DISORGANIZED CONVECTION. UPPER-LEVEL ANALYSIS
INDICATES THAT THE LLCC IS LOCATED 10 DEGREES SOUTH OF THE RIDGE AXIS
IN AN AREA OF MODERATE TO STRONG (20 TO 30 KNOT) EASTERLY VERTICAL
WIND SHEAR; HOWEVER, A STRONG POLEWARD DIFFLUENCE IS SUSTAINING THE
ASSOCIATED CONVECTION, AS SEEN ON ANIMATED WATER VAPOR SATELLITE
IMAGERY. NUMERIC MODEL GUIDANCE SUGGEST WEAK DEVELOPMENT AFTER 72
HOURS OVER THE PHILIPPINE SEA. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. DUE TO THE CONTINUED UNFAVORABLE ENVIRONMENT, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS LOW.

There are three kinds of JMA TDs: NTD, WTD and ExpT. 94W is the second, which means a TD with a warning.
