REMARKS:
130900Z POSITION NEAR 21.4N 64.3E.
TROPICAL CYCLONE 02A (NANAUK), LOCATED APPROXIMATELY 258 NM
SOUTHWEST OF KARACHI, PAKISTAN, HAS TRACKED NORTHWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) CLEARLY SHOWS THE FULLY-EXPOSED LOW LEVEL CIRCULATION CENTER
HAS DRIFTED NORTHWARD FROM THE CENTRAL DENSE OVERCAST (CDO) BY OVER
200 NM AND HAS BEGUN TO UNRAVEL. THE SAME ANIMATION SHOWS THE CDO
FEATURE REMAINS EXPANSIVE AND DEEP AS STRONG OUTFLOW – GENERATED BY
THE TROPICAL EASTERLY JET WINDS – PROVIDE EXCELLENT VENTILATION. THE
INITIAL POSITION IS BASED ON THE MSI ANIMATION WITH HIGH CONFIDENCE.
THE INITIAL INTENSITY IS BASED ON DVORAK ESTIMATES FROM PGTW AND KNES
AND FROM RECENT SCATTEROMETRY DATA. UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM IS SOUTH OF THE RIDGE AXIS IN AN AREA OF STRONG (40-50
KNOT) NORTHEASTERLY VERTICAL WIND SHEAR. TC 02A IS EXPECTED TO REMAIN
DECOUPLED FROM ITS ASSOCIATED CONVECTION AND DRIFT POLEWARD WITH THE
850 MB FLOW AND DISSIPATE BY TAU 12. NUMERIC MODEL GUIDANCE, TYPICAL
WITH RAPIDLY WEAKENING VORTICES, HAS BECOME WIDELY SPREAD, LENDING
LOW CONFIDENCE TO THE JTWC TRACK FORECAST. 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 130600Z IS 12 FEET.
