REMARKS:
170300Z1 POSITION NEAR 18.0N9 84.9E1.
TROPICAL CYCLONE (TC) 04B HAS TRACKED WEST-NORTHWESTWARD AT 06
KNOTS, APPROXIMATELY 65 NM EAST-SOUTHEAST OF THE COAST OF INDIA, AND
HAS RAPIDLY INTENSIFIED OVER THE PAST 6 HOURS. THEREFORE, AN
ADDITIONAL WARNING HAS BEEN GENERATED FOR THIS SYSTEM. THE WARNING
POSITION IS BASED UPON 162330Z5 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED UPON SATELLITE CURRENT INTENSITY
ESTIMATES OF 127 KNOTS AND A RECENT TROPICAL RAINFALL MEASURING
MISSION (TRMM) PASS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS A SMALL, TIGHT SYMMETRICAL SYSTEM WITH A COMPACT 5 NM EYE.
THE TRMM PASS SHOWS A BANDING FEATURE COMPLETELY ENCLOSING THE EYE.
ANOTHER STRONG CONVECTIVE BAND IS SITUATED WEST THROUGH SOUTHWEST OF
THE VORTEX. OUTFLOW REMAINS GOOD WITH AN UPPER-LEVEL ANTICYCLONE NOW
SITUATED OVER THE SYSTEM. THE SYSTEM SHOULD MAINTAIN INTENSITY OVER
THE NEXT 8 TO 1O HOURS BEFORE REACHING THE COAST. AFTER LANDFALL,
THE SYSTEM WILL DISSIPATE RAPIDLY. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 170000Z IS 12 FEET. REFER TO WWPW30 RJTX FOR ADDITIONAL SEA
HEIGHT INFORMATION. NEXT WARNINGS AT 170900Z7 (DTG 170753Z3),
172100Z1 (DTG 171953Z6).//
