TROPICAL CYCLONE FORMATION ALERT CANCELLATION ..
THIS CANCELS REF A (WTIO21 PGTW 220730). THE AREA OF 
CONVECTION PREVIOUSLY LOCATED NEAR 16.5N 91.6E IS NOW LOCATED NEAR 16.2N 91.0E, APPROXIMATELY 370 NM SOUTH OF CHITTAGONG, BANGLADESH. 

RECENT ANIMATED INFRARED SATELLITE IMAGERY SHOWS PATCHY DEEP CONVECTION FLARING AND DISSIPATING OVER THE WESTERN PORTION OF A LOW-LEVEL CIRCULATION CENTER (LLCC) EVIDENT IN A 222238Z SSMIS PASS. 
::
THIS DISTURBANCE HAS WEAKENED SLIGHTLY OVER THE PAST TWELVE HOURS IN RESPONSE TO PERSISTENT VERTICAL WIND SHEAR INDUCED BY THE PERIPHERAL FLOW AROUND AN UPPER-LEVEL RIDGE TO THE NORTH. 

EASTERLY VERTICAL WIND SHEAR IS EXPECTED TO IMPACT THE SYSTEM FOR THE NEXT 24 HOURS, RENDERING THE FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IN THAT TIME FRAME UNLIKELY. 

MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. 
::
BASED ON THE OBSERVED WEAKENING TREND AND CONSIDERING THE POTENTIAL FOR REDEVELOPMENT IF VERTICAL WIND SHEAR RELAXES OVER THE NEXT FEW DAYS, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO MEDIUM.
