18JUL25. TROPICAL CYCLONE 01S (ONE), LOCATED APPROXIMATELY 666 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 15 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE
IMAGERY DEPICTS 01S NEARLY COMPLETELY VOID OF DEEP CONVECTION WITH
AN INCREASINGLY DISORGANIZED LOW-LEVEL CIRCULATION CENTER (LLCC).
AN 181609Z METOP-B ASCAT PASS REVEALED WEAK WINDS (5-10 KTS) WITHIN
THE NORTHERN SEMICIRCLE AND 25-30 KTS WITHIN THE SOUTHERN
SEMICIRCLE, WHICH SUPPORTED THE INITIAL INTENSITY ESTIMATE. THE
ENVIRONMENT IS EXPECTED TO WORSEN AS DRY AIR ENTRAINS INTO THE
VORTEX FROM THE NORTH AND NORTHERLY VERTICAL WIND SHEAR INCREASES.
NUMERICAL MODEL GUIDANCE IS IN AGREEMENT ON THE TRACK OF 01S AND
AGREES ON A GRADUAL WEAKENING TREND OVER THE NEXT 48 HOURS.
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 181800Z IS
