1. REMARKS: THIS CANCELS REF A (WTPN21 PGTW 300100). THE AREA OF
CONVECTION (INVEST 95W), PREVIOUSLY LOCATED NEAR 19.6N 139.3E IS NOW
LOCATED NEAR 22.5N 134.2E, APPROXIMATELY 370 NM EAST-SOUTHEAST OF
KADENA AB. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) INDICATES
A VERY BROAD AND ILL-DEFINED LOW LEVEL CIRCULATION (LLC) WITH
CONVECTION BEING SHEARED TO THE SOUTH-SOUTHWEST. INVEST 95W IS IN AN
UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT CHARACTERIZED BY WARM (29-
30C) SEA SURFACE TEMPERATURES AND EQUATORWARD OUTFLOW ALOFT OFFSET
BY VERY HIGH (30-40 KNOTS) VERTICAL WIND SHEAR(VWS). GLOBAL MODELS
DO NOT INDICATE FURTHER DEVELOPMENT FOR INVEST 95W. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS DOWNGRADED TO LOW.//
