REMARKS:
250300Z POSITION NEAR 35.9N 156.9E.
TROPICAL STORM (TS) 17W (ATSANI), LOCATED APPROXIMATELY 1065 NM 
SOUTH OF PETROPAVLOVSK, HAS TRACKED EAST-NORTHEASTWARD AT 20 KNOTS 
OVER THE PAST SIX HOURS. ANIMATED MSI SHOWS MINIMAL SPIRAL BANDING 
WRAPPING INTO AN ELONGATED RAGGED CIRCULATION. THE INITIAL POSITION 
IS BASED ON THE AFOREMENTIONED MSI AND A 242036Z SSMIS IMAGE WITH 
MODERATE CONFIDENCE. THE NORTHERN PORTION OF THE SYSTEM IS 
CURRENTLY INTERACTING WITH THE MID-LATITUDE BAROCLINIC ZONE AS THE 
SYSTEM TRACKS ALONG THE NORTHERN PORTION OF THE STR. FINALLY, A 
241933Z AMSU-B CROSS SECTION ANALYSIS SHOWS THAT THE SYSTEM HAS 
MAINTAINED A DEEP WARM CORE, HOWEVER WINDS ARE PLACED SIGNIFICANTLY 
FAR FROM THE LLCC, SPECIFICALLY IN THE SOUTHEASTERN QUADRANT, 
INDICATING THE SYSTEM HAS BEGUN ETT. TS 17W WILL CONTINUE 
NORTHEASTWARD IN THE MID-LATITUDE WESTERLY FLOW AND CONTINUE 
INTERACTING WITH THE BAROCLINIC ZONE. BY TAU 24, TY ATSANI 
WILL BECOME FULLY ENVELOPED INTO THE BAROCLINIC ZONE, HAVING 
COMPLETED ETT. MODEL GUIDANCE IS IN VERY TIGHT AGREEMENT THROUGH 
TAU 24 GIVEN HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250000Z
IS 22 FEET. REFER TO TYPHOON 16W (GONI) WARNINGS (WTPN31 PGTW)
FOR SIX-HOURLY UPDATES.//
