1.REMARKS: THIS CANCELS REF A (WTIO21 PGTW 090900). THE AREA OF CONVECTION 
(INVEST 92B) PREVIOUSLY LOCATED NEAR 19.3N 86.6E, IS NOW LOCATED 17.9N 
86.7E, APPROXIMATELY 200NM SW OF KOLKATA, INDIA. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY DEPICTS A FULLY-EXPOSED AND ELONGATED LOW-LEVEL 
CIRCULATION CENTER (LLCC) WITH DISPLACED CONVECTION TO THE WEST OF CENTER. 
UPPER-LEVEL ANALYSIS INDICATED THE SYSTEM HAS CLOSED PROXIMITY TO AN 
UPPER-LEVEL CYCLONE OVER NORTHERN INDIA. GLOBAL MODELS INDICATE PERSISTENT 
HIGH VERTICAL WIND SHEAR WITH A SHARP GRADIENT TO LOW VERTICAL WIND SHEAR 
ACROSS THE NORTHERN BAY OF BENGAL AND NORTHEASTERN INDIA, AND AS SUCH, THE 
MODEL SOLUTIONS ARE NO LONGER INTENSIFYING THIS SYSTEM AS A TROPICAL 
CYCLONE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED TO BE AT 28 TO 33 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 992 MB. IN VIEW 
OF THE UNFAVORABLE FORECAST FOR THIS SYSTEM, INVEST 92B HAS DISSIPATED 
OVER LAND AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE IN THE NEXT 24 HOURS.//
