1. REMARKS: THIS CANCELS REF A (WTPN PHNC 071900). THE AREA OF
CONVECTION (INVEST 97E) PREVIOUSLY LOCATED NEAR 17.3N 105.1W, IS
NOW LOCATED NEAR 19.4N 106.2W, APPROXIMATELY 107 NM SOUTHWEST OF
PUERTO VALLARTA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A 
FULLY EXPOSED AND RAGGED LOW LEVEL CIRCULATION CENTER (LLCC) WITH 
WEAKENED CONVECTION DISPLACED WESTWARD OF THE LLCC. UPPER-LEVEL 
ANALYSIS INDICATES THE SYSTEM HAS LOST HEALTHY AMOUNTS OF UPPER LEVEL 
OUTFLOW, WHICH IS FORECAST TO PERSIST. GLOBAL MODELS NOW INDICATE NO 
SIGNIFICANT DEVELOPMENT AS THE SYSTEM TRACKS WESTWARD OVER THE NEXT TWO 
DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 0 TO 0 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1021 MB. 
THIS SYSTEM IS NO LONGER EXPECTED TO DEVELOP INTO A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS.//
