A rebranded 91W perhaps?

AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR
32.2N 136.3E, APPROXIMATELY 248 NM SOUTHWEST OF YOKOSUKA, JAPAN.
ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS A BROAD
AREA OF CONVECTION WITH MINIMAL TURNING. A 221629Z AMSR2 89GHZ
SATELLITE IMAGE REVEALS POCKETS OF DEEP CONVECTION DISPLACED TO THE
EAST AND SOUTHEAST OF A LOW LEVEL CIRCULATION (LLC) WITH SOME LOW-
LEVEL CONVECTIVE BANDING WRAPPING INTO THE LLC. A 221030Z SCATSAT
IMAGE DEPICTS A BAND OF 30-35KT WINDS DISPLACED TO THE SOUTHEAST OF
THE LLC. THE ENVIRONMENT IS CONDUCIVE FOR FURTHER DEVELOPMENT WITH
POLEWARD UPPER LEVEL OUTFLOW, AND A MARGINAL EQUATORWARD OUTFLOW
CHANNEL THAT IS INHIBITED BY THE OUTFLOW OF TC 09W, AND WARM (30-31
CELSIUS) SEA SURFACE TEMPERATURES OFFSET BY MODERATE (10-15 KT)
VERTICAL WIND SHEAR. NUMERICAL MODELS ARE IN GENERAL AGREEMENT THAT
THE SYSTEM WILL DISSIPATE AS IT TRACKS EAST-NORTHEASTWARD. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.

JMA "LOW" (subtropical?). Looks like something that can be called a subtropical depression in other basins.

LOW 1006 HPA AT 32N 136E ENE SLOWLY.

THE AREA OF CONVECTION (INVEST 93W) PREVIOULSY LOCATED
NEAR 32.2N 136.3E, IS NOW LOCATED NEAR 32.3N 137.3E APPROXIMATELY
235 NM SOUTHWEST OF YOKOSUKA, JAPAN. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY DEPICTS A BROAD AREA OF WEAK CONVECTION WITH
MINIMAL TURNING. A 230031Z 89GHZ METOP-B SATELLITE IMAGE SHOWS A
POCKET OF DEEP CONVECTION DISPLACED TO THE SOUTHEAST OF THE CENTER.
93W IS CURRENTLY IN AN ENVIRONMENT MARGINALLY FAVORABLE FOR
DEVELOPMENT WITH POLEWARD UPPER LEVEL OUTFLOW AND WARM (30-31
CELSIUS) SEA SURFACE TEMPERATURES OFFSET BY MODERATE (15-25 KT)
VERTICAL WIND SHEAR. NUMERICAL MODELS ARE IN GENERAL AGREEMENT THAT
THE SYSTEM WILL DISSIPATE AS IT TRACKS EAST-NORTHEASTWARD. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS LOW.

I wish JTWC would start recognizing subtropical systems in the WPAC. That is why the Atlantic has seen an increase in their numbers and named storms because NHC started doing so in 2002.

Probrably a couple of these every year yet IGNORED.

THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 32.3N 137.3E, IS NOW LOCATED NEAR 32.5N 140.7E APPROXIMATELY 86
NM OF YOKOSUKA, JAPAN. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
AND A 240010Z 89GHZ METOP-B SATELLITE IMAGE DEPICT A BROAD AREA OF
WEAK CONVECTION WITH MINIMAL TURNING. 93W IS CURRENTLY IN AN
ENVIRONMENT MARGINALLY FAVORABLE FOR DEVELOPMENT WITH GOOD POLEWARD
UPPER LEVEL OUTFLOW AND WARM (28-29 CELSIUS) SEA SURFACE
TEMPERATURES OFFSET BY MODERATE (15-25 KT) VERTICAL WIND SHEAR.
NUMERICAL MODELS ARE IN GENERAL AGREEMENT THAT THE SYSTEM WILL
DISSIPATE AS IT TRACKS EAST-NORTHEASTWARD. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A

THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 32.3N 137.3E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
