Cyclone "03 A" .. Update # 17 ... Invisible, yet power packed. Very near to Pakistan & Gujarat

JTWC warning
------------------------

060300Z POSITION NEAR 23.0N 64.8E.
TROPICAL CYCLONE (TC) 03A (PHET), LOCATED APPROXIMATELY 200 NM 
SOUTHWEST OF KARACHI, PAKISTAN, HAS TRACKED EASTWARD AT 16 KNOTS 
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY AND A 
052140Z AMSU IMAGE CONTINUE TO DEPICT AN EXPOSED, BUT WELL-DEFINED 
LOW-LEVEL CIRCULATION CENTER (LLCC) WITH ISOLATED DEEP CONVECTION 
SHEARED 200 NM NORTHEAST OF THE CENTER. DVORAK ESTIMATES HAVE 
CONTINUED TO DECREASE AND CURRENTLY RANGE FROM 25 KNOTS (FT) TO 30 
KNOTS (CI). THE CURRENT INTENSITY OF 40 KNOTS IS BASED ON THE 
051350Z WINDSAT IMAGE, WHICH INDICATED 35-40 KNOT GALES SURROUNDING 
THE SYSTEM AS WELL AS THE LLCC SATELLITE SIGNATURE. TC 03A HAS 
ACCELERATED EASTWARD AND IS EXPECTED TO CONTINUE TRACKING EASTWARD 
TOWARD KARACHI. BASED ON THE WELL-DEFINED SHALLOW LLCC, WINDSAT AND 
WARM CORE (05/12Z AMSU TEMPERATURE ANOMALY PLOT), THE SYSTEM IS 
EXPECTED TO MAINTAIN 35-40 KNOT INTENSITY UNTIL IT MAKES LANDFALL 
AFTER TAU 12. AVAILABLE GUIDANCE REMAINS IN TIGHT AGREEMENT, 
THEREFORE THIS FORECAST IS BASED ON THE CONSENSUS OF THE MODEL 
TRACKERS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 060000Z IS 16 FEET.
