REMARKS:
242100Z9 POSITION 32.1N6  150.8E4
TROPICAL DEPRESSION 11W IS MOVING WEST-NORTHWESTWARD AT
04 KNOTS. THE DEVELOPMENT OF THE SYSTEM IS BEING HINDERED
BY THE STRONG OUTFLOW FROM TYPHOON ROSIE (10W). THE SHEAR
IS NOT EXPECTED TO DIMINISH OVER THE NEXT 36 HOURS WHICH
WILL WEAKEN THE SYSTEM THROUGHOUT THE FORECAST PERIOD. TD
11W IS FORECAST TO BE DISSIPATED BY THE 36-HOUR FORECAST
POSITION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241800Z5 IS
09 FEET. REFER TO WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. NEXT WARNINGS AT 250900Z6 (DTG 250753Z2) AND
252100Z0 (DTG 251953Z5). IF THE JOINT TYPHOON WARNING
CENTER ANTICIPATES THAT TROPICAL DEPRESSION 11W WILL
REACH TROPICAL STORM INTENSITY, THEN A STANDARD 72 HOUR
TROPICAL CYCLONE WARNING WILL BE ISSUED.  OTHERWISE, 36
HOUR TROPICAL DEPRESSION WARNINGS WILL BE UPDATED EVERY
12 HOURS. REFER TO TYPHOON ROSIE (10W) WARNINGS (WTPN31
PGTW) FOR TWELVE-HOURLY UPDATES.//
