Interesting... JTWC upgrade?
I had the same question but it still says POOR.

AN AREA OF CONVECTION HAS PERSISTED NEAR 20.3N 90.1E,
APPROXIMATELY 165 NM SOUTHEAST OF CALCUTTA, INDIA. RECENT ANIMATED
INFRARED SATELLITE IMAGERY INDICATES A BROAD AREA OF LOW TO MID-
LEVEL CYCLONIC TURNING ASSOCIATED WITH THE MONSOON TROUGH. A 151158Z
QUIKSCAT IMAGE SECONDS A BROAD AND WEAK LOW LEVEL CIRCULATION CENTER
WITH ENHANCED GRADIENT WINDS TO THE SOUTH. SURFACE OBSERVATIONS FROM
CALCUTTA, INDIA, AS OF 151720Z, REVEAL 2 MB PRESSURE FALLS OVER THE
PAST 24 HOURS AS WELL. A 151319Z SSMIS MICROWAVE IMAGE DEPICTS TWO
PRIMARY AREAS OF CONVECTION ASSOCIATED WITH THE SYSTEM, WITH THE
CONVECTION TO THE NORTH BEING ENHANCED BY TERRESTRIAL EFFECTS. THE
UPPER LEVEL ENVIRONMENT IS HAMPERING LOW LEVEL ORGANIZATION WITH
MODERATE TO HIGH VERTICAL WIND SHEAR; HOWEVER, ADEQUATE UPPER LEVEL
DIFFLUENCE CONTINUES TO SUSTAIN DEEP CONVECTION. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. DUE TO THE RECENT
REBUILDING OF DEEP CONVECTION YET DISORGANIZED LOW LEVEL, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS POOR.
