REMARKS:
010300Z POSITION NEAR 24.5N 129.0E.
01SEP22. TROPICAL DEPRESSION (TD) 13W (THIRTEEN), LOCATED
APPROXIMATELY 163 NM SOUTH-SOUTHEAST OF KADENA AB, OKINAWA, JAPAN,
HAS TRACKED NORTHWESTWARD AT 15 KNOTS OVER THE PAST SIX HOURS.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A WEAK, PARTLY EXPOSED
LOW LEVEL CIRCULATION (LLC) WITH FRESH BUT SHALLOW CONVECTION SHEARED
WESTWARD OF THE LLC. THE INITIAL POSITION IS PLACED WITH MEDIUM
CONFIDENCE BASED ON THE PARTLY EXPOSED LLC. THE INITIAL INTENSITY IS
EXTRAPOLATED FROM NEARBY SURFACE OBSERVATIONS AND FROM RECENT
SCATTEROMETY DATA. TD 13W IS FAST BECOMING EMBEDDED INTO THE WIND
FIELD OF SUPER TYPHOON 12W. IT IS EXPECTED TO TRACK WEST-
NORTHWESTWARD UP TO TAU 12 TO APPROXIMATELY 60NM SOUTH OF KADENA AB,
THEN WEST-SOUTHWESTWARD TOWARD MIYAKOJIMA. THE SYSTEM IS EXPECTED TO
OPEN UP INTO A WAVE BEFORE TAU 12 AND MAY ENHANCE WINDS OVER SOUTHERN
OKINAWA, AS IT GETS EMBEDDED INTO THE NEAR GALE WIND FIELD OF STY
12W. THERE IS LOW CONFIDENCE IN THE JTWC TRACK FORECAST AS THE
NUMERICAL MODELS LOSE THE TD 13W VORTEX AND JUMP INTO THE STY 12W
VORTEX. ADDITIONALLY, THE LLC IS FORECAST TO OPEN INTO A WAVE, AS
DEPICTED IN NUMERIC MODEL FIELDS, WHERE THE FORECAST TRACK IS BASED
ON. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR
SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 010000Z IS
10 FEET. REFER TO SUPER TYPHOON 12W (HINNAMNOR) WARNINGS (WTPN31
PGTW) FOR SIX-HOURLY UPDATES.//
