TROPICAL CYCLONE 09S (SELWYN) HAS MOVED WESTWARD AT 07
KNOTS FOR THE PAST 06 HOURS. THE WARNING POSITION IS
BASED ON 202330Z0 VISIBLE SATELLITE IMAGERY ANALYZED BY
PHIK ANALYSTS AND CONTINUITY FROM A 301611Z2 SCATTEROMETER
PASS WHICH ALSO INDICATED THAT THE MAXIMUM INTENSITY WAS 35
KNOTS. THE CONVECTION WITH THIS SYSTEM HAS DIMINISHED WITH
THE NEAREST CONVECTIVE CELLS LOCATED APPROXIMATELY 65NM FROM
THE SYSTEM CENTER. TROPICAL CYCLONE 09S (SELWYN) SHOULD
CONTINUE WESTWARD FOR THE NEXT 24 HOURS AS IT IS STEERED
PRIMARILY BY LOW LEVEL FLOW FROM HIGH PRESSURE LOCATED SOUTH
OF THE CENTER. THE SYSTEM SHOULD CONTINUE TO WEAKEN SLOWLY
THROUGHOUT THE PERIOD AS AN UPPER LEVEL TROUGH APPROACHES
FROM THE WEST INCREASING THE VERTICAL WIND SHEAR. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 310000Z IS 13 FEET. NEXT WARNINGS
AT 311500Z0 (DTG 311353Z6).//
