1. REMARKS: THIS CANCELS REF A (WTPN21 PHNC 140200). THE AREA OF 
CONVECTION (INVEST 91C) PREVIOUSLY LOCATED 8.8N 154.9W, APPROXIMATELY 
462 NM EAST NORTH-EAST OF PALMYRA. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS A PARTIALLY EXPOSED, DISORGANIZED CIRCULATION WITH 
SUPPRESSED POLEWARD OUTFLOW ALOFT. THE CONVECTION IS BECOMING LESS 
INTENSE AND WIDESPREAD DUE TO PERSISTENT MODERATE TO STRONG EASTERLY 
WIND SHEAR. A 141946Z ASCAT-B IMAGE DEPICTS A VERY ELONGATED CIRCULATION 
WITH 15-20 KT WINDS IN THE SOUTHERN PERIPHERY. GLOBAL DETERMINISTIC AND 
ENSEMBLE MODELS ARE SHOWING (INVEST 91C) TO CONTINUE WEAKENING AS IT 
KEEPS MOVING NORTH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 
TO 33 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 DOWNGRADED TO LOW.//
