Western Pacific: remnants of 16W still Medium//Eastern Pacific:12E(LINDA) still a CAT 2 annular Hurricane//Atlantic: 07L&08L forecast to reach Hurricane intensity,18/06utc updates



THE AREA OF CONVECTION (INVEST 16W) PREVIOUSLY LOCATED NEAR 13.5N 143.3E IS NOW LOCATED NEAR 14.3N 138.1E, APPROXIMATELY 720 KM WEST OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 180413UTC ASMR2 89GHZ IMAGE DEPICT DEEP CONVECTION OVER AN OBSCURED LOW LEVEL CENTER. A 180042UTC ASCAT PASS REVEALS A CLOSED, BROAD CIRCULATION WITH POCKETS OF 20KNOT WIND OFFSET TO THE EAST AND NORTH OF THE CENTER. THE OVERALL ENVIRONMENT IS FAVORABLE WITH WARM SST VALUES (31-32 CELSIUS), LOW VERTICAL WIND SHEAR (05-10 KTS) AND DUAL CHANNEL OUTFLOW. 16W WILL CONTINUE TO TRACK WEST WITH NUMERICAL MODELS HAVING MINOR INTESIFICATION THROUGH 24-48H. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 REMAINS MEDIUM.
