REMARKS:
172100Z POSITION NEAR 10.8S 91.2E.
17DEC25. TROPICAL CYCLONE 07S (BAKUNG), LOCATED APPROXIMATELY 331
NM WEST?NORTHWEST OF THE COCOS ISLANDS, HAS TRACKED NORTH?
NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS 07S WITH A DECOUPLED  LOW-LEVEL
CIRCULATION CENTER (LLCC) THAT IS DISPLACED FAR TO THE NORTHWEST OF
THE DEEP CONVECTION. A 171533Z METOP-B ASCAT PASS REVEALED A HIGHLY
ASYMMETRIC WIND FIELD WITH WINDS OF 25-30 KTS CONFINED TO THE
SOUTHERN SEMICIRCLE. WINDS WITHIN THE NORTHERN PERIPHERY OF THE LLCC
ARE MUCH LOWER, AT AROUND 10-15 KTS. ENVIRONMENTAL ANALYSIS
INDICATES THAT 07S IS IN AN UNFAVORABLE ENVIRONMENT CHARACTERIZED
BY WEAK POLEWARD OUTFLOW, HIGH (25-30 KTS) NORTHEASTERLY VERTICAL
WIND SHEAR, AND SIGNIFICANT DRY AIR ENTRAINMENT. 07S IS FORECAST TO
TRACK GENERALLY NORTHWESTWARD OVER THE NEXT 24 HOURS AND THE HOSTILE
ENVIRONMENT IS EXPECTED TO CAUSE GRADUAL WEAKENING. 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. MINIMUM CENTRAL PRESSURE AT 171800Z IS 1004 MB.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171800Z IS 14 FEET.//
