REMARKS:
210900Z2 POSITION NEAR 17.5S3 77.7E1.
TROPICAL CYCLONE (TC) 06S (CHARLY), LOCATED APPROXIMATELY 850 NM
EAST OF PORT MATHURIN, HAS TRACKED WESTWARD AT 11 KNOTS DURING THE
PAST 6 HOURS. THE WARNING POSITION IS BASED ON 210530Z1 VISIBLE AND
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 65 TO 77 KNOTS. ANIMATED
MULTI-SPECTRAL SATELLITE IMAGERY SHOWS THE SYSTEM POSSESSES A
BANDING EYE WITH THE DEEPEST CONVECTION IN THE NORTHERN SEMI-CIRCLE.
A 210341Z1 SPECIAL SENSOR MICROWAVE IMAGER PASS DEPICTED A PRIMARY
BAND WRAPPING INTO THE WESTERN QUADRANT OF THE SYSTEM. THE 200 MB
ANALYSIS INDICATES THE SYSTEM REMAINS BENEATH THE UPPER LEVEL RIDGE.
TC 06S IS EXPECTED TO TRACK WITHIN A WEAKNESS IN THE MID-LEVEL
RIDGE CREATED BY AN APPROACHING MID-LAT TROUGH THROUGH THE FORECAST
PERIOD. TC 06S SHOULD TRACK IN A WEST-SOUTHWESTWARD TRACK AND MOVE
POLEWARD OF THE UPPER LEVEL RIDGE AXIS. THE SYSTEM SHOULD BEGIN
WEAKENING BY MID-PERIOD AS IT ENCOUNTERS INCREASING VERTICAL WIND
SHEAR. THE WIND RADII HAS BEEN ADJUSTED BASED ON A RECENT QUIKSCAT
PASS OVER THE SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201800Z1 IS
18 FEET. NEXT WARNINGS AT 212100Z6 (DTG 211951Z9) AND 220900Z3 (DTG
220751Z7).//
