REMARKS:
160900Z6 POSITION NEAR  7.0S7  134.0E8.
TROPICAL CYCLONE (TC) 20S HAS DEVELOPED OVER THE ARAFURA SEA ALONG A
MONSOON TROUGH. TROPICAL CYCLONE 20S HAS TRACKED WESTWARD AT 05
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
160530Z5 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 25 TO 35 KNOTS.  SATELLITE
ANIMATION DEPICTS INCREASING COVERAGE AS OUTFLOW ALOFT HAS IMPROVED
OVER THE NORTHWEST QUADRANT. TC 20S SHOULD TRACK WEST-SOUTHWESTWARD
WITHIN THE LOW/MID LEVEL TROPICAL EASTERLIES THROUGH THE PERIOD. THE
UPPER RIDGE CURRENTLY SITUATED OVER NORTHERN AUSTRALIA SHOULD REMAIN
QUASI-STATIONARY, THEREFORE, SLOW DEVELOPMENT OF THE SYSTEM IS
FORECAST AS LIGHT TO MODERATE UPPER EASTERLIES INHIBIT SIGNIFICANT
DEVELOPMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150600Z2 IS 10 FEET.
