WEST-NORTHWEST OF PORT SAN 
ESTEBAN
, PHILLIPINES, HAS TRACKED 
EASTWARD AT 10 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS 
BASED ON 202330Z0 VISIBLE AND INFRARED SATELLITE IMAGERY. THE 
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES 
OF 25 KNOTS AND SYNOPTIC REPORTS NEAR 30 KNOTS. ANIMATED SATELLITE 
IMAGERY DEPICTS CONVECTION ORGANIZING AROUND A LOW-LEVEL CIRCULATION 
CENTER (LLCC), WITH PREDOMINANT CONVECTION BEING PULLED TO THE 
NORTHEAST. TD 03W IS A HYBRID SYSTEM CURRENTLY UNDERGOING 
EXTRATROPICAL TRANSITION. THE SYSTEM IS FORECAST TO TRACK TO THE 
EAST-NORTHEAST IN THE MID-LATITUDE WESTERLY FLOW. TD 03W WILL 
INTENSIFY SLIGHTLY AS IT MOVES INTO INCREASING VERTICAL WIND SHEAR. 
EXTRATROPICAL TRANSITION WILL BE COMPLETE WITHIN THE NEXT 24-36 
HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 210000Z3 IS 10 FEET. REFER 
TO WWPW31 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS 
AT 210900Z2 (DTG 210751Z6), 211500Z9 (DTG 211351Z3), 212100Z6 (DTG
