REMARKS:
242100Z9 POSITION 16.5N2  135.3E2
TROPICAL STORM ZANE (29W) IS MOVING WEST-NORTHWESTWARD AT
12 KNOTS. IT IS STILL A RATHER BROAD SYSTEM, BUT ENHANCED
INFRARED SATELLITE IMAGERY INDICATES THE SYSTEM
ORGANIZATION IS IMPROVING. WATER VAPOR IMAGERY DERIVED
WINDS, COURTESY OF UW-CIMSS, INDICATE THIS SYSTEM HAS
VERY GOOD OUTFLOW ALOFT. THIS, COUPLED WITH STRONG LOW-
LEVEL INFLOW AND VERY WARM SEA SURFACE CONDITIONS,
INDICATES THE SYSTEM SHOULD CONTINUE TO INTENSIFY. TS
ZANE LIES WITHIN THE MONSOON TROUGH AND HAS A WELL
DEFINED SUBTROPICAL RIDGE TO ITS NORTH. THIS RIDGE SHOULD
FORCE TS ZANE INTO A MORE WESTWARD TRACK BEYOND 24 HOURS.
TS ZANE APPEARS TO ALREADY BE TURNING WESTWARD AND
SLOWING ITS FORWARD MOTION IN RESPONSE TO THIS RIDGE. TS
ZANE IS FORECAST TO DRAMATICALLY SLOW ITS FORWARD MOTION
NEAR THE 72 HOUR POSITION DUE TO INTERACTION WITH TY
YATES (28W) TO ITS EAST. TY YATES IS FORECAST TO BE
MOVING NORTH TOWARD A BREAK IN THE SUBTROPICAL RIDGE AXIS
AT THIS POINT IN TIME AND THIS NORTHWARD MOTION IS
EXPECTED TO SLOW THE MOTION OF TS ZANE TOWARD THE WEST.
NEXT WARNINGS AT 250300Z0 (DTG 250153Z6), 250900Z6 (DTG
250753Z2), 251500Z3 (DTG 251353Z9) AND 252100Z0 (DTG
251953Z5). MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241800Z5 IS
19 FEET. REFER TO WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. REFER TO TYPHOON YATES (28W) WARNINGS
(WTPN31 PGTW) FOR SIX-HOURLY UPDATES.//
