REMARKS:
152100Z POSITION NEAR 40.8N 142.2E.
15JUL25. TROPICAL DEPRESSION 08W (EIGHT), LOCATED APPROXIMATELY
56 NM SOUTH-SOUTHEAST OF MISAWA, JAPAN, HAS TRACKED NORTHWARD AT
30 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS 08W WITH A RAPIDLY DETERIORATING LOW-LEVEL
CIRCULATION CENTER (LLCC) AS IT QUICKLY TRAVERSES ACROSS NORTHERN
HONSHU. AS THE SYSTEM CONTINUES TO GAIN LATITUDE, THE ENVIRONMENT
WILL ONLY WORSEN WITH INCREASING VERTICAL WIND SHEAR AND COLD SEA
SEA SURFACE TEMPERATURES. AS A RESULT, 08W IS FORECAST TO CONTINUE
WEAKENING AS IT TRACKS OFF TO THE NORTHEAST OVER THE NEXT 24 HOURS
AND BECOMES WASHED OUT BY THE STRONG UPPER-LEVEL WINDS ASSOCIATED
WITH THE JET. DETERMINISTIC AND ENSEMBLE MODEL GUIDANCE OVERALL
AGREES ON THE TRACK AND CONTINUED WEAKENING TREND OF THE SYSTEM.
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 151800Z IS
1006 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151800Z IS 12 FEET.//
