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

050900Z POSITION NEAR 23.8N 61.4E.
TROPICAL CYCLONE (TC) 03A (PHET), LOCATED APPROXIMATELY 330 NM
WEST OF KARACHI, PAKISTAN, HAS TRACKED EASTWARD AT 06 KNOTS OVER THE 
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS AN 
EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH THE DEEPEST 
CONVECTION SHEARED 52 NM FROM THE CENTER IN THE NORTHERN SEMICIRCLE. 
INITIAL INTENSITY IS BASED ON THE PGTW DVORAK ESTIMATE OF 35 KNOTS. 
ENVIRONMENTAL ANALYSIS INDICATES TC 03A IS LOCATED POLEWARD OF THE 
SUBTROPICAL RIDGE AXIS IN AN AREA OF MODERATE TO HIGH VERTICAL WIND 
SHEAR (VWS). TC PHET IS EXPECTED TO ACCELERATE EASTWARD AS IT 
INTERACTS WITH THE MID-LATITUDE WESTERLY FLOW. DUE TO THE HIGH VWS, 
TC 03A IS FORECAST TO WEAKEN AND DISSIPATE AS A SIGNIFICANT TROPICAL 
CYCLONE BY TAU 24, BEFORE MAKING LANDFALL NEAR KARACHI. THIS 
FORECAST IS IN GOOD AGREEMENT WITH THE NUMERICAL MODEL CONSENSUS. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 050600Z IS 20 FEET.
