REMARKS:
090900Z POSITION NEAR 34.6N 136.8E.
09SEP26. TROPICAL DEPRESSION 22W (KROVANH), LOCATED APPROXIMATELY
187 NM WEST-SOUTHWEST OF ATSUGI, JAPAN, HAS TRACKED EAST-
NORTHEASTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. TROPICAL
DEPRESSION 22W HAS BECOME INCREASINGLY RAGGED AND ILL-DEFINED
AS IT RAKES ACROSS THE COAST OF HONSHU. SURFACE OBSERVATIONS FROM
THE REGION ARE DEPICTING WEAK (<20 KTS) WIND SPEEDS AND INCONSISTENT
WIND DIRECTIONS, INDICATING THE SURFACE CIRCULATION IS FALLING APART.
22W IS FORECAST TO CONTINUE TRACKING GENERALLY NORTHEASTWARD WHILE
FURTHER UNRAVELING. THE ENVIRONMENT IS EXPECTED TO REMAIN HOSTILE,
CHARACTERIZED BY LARGE AMOUNTS OF DRY AIR, HIGH (40-45 KTS) VERTICAL
WIND SHEAR, AND LAND INTERACTION. GLOBAL DETERMINISTIC MODELS ARE IN
STRONG AGREEMENT IN IMMINENT DISSIPATION. AS THE REMNANT CIRCULATION
TRACKS ALONG THE COASTLINE, ELEVATED WINDS MAY OCCUR OFFSHORE DUE
TO TERRAIN INTERACTION. 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
090600Z IS 1003 MB.//
