REMARKS:
061500Z2 POSITION 13.2N6   69.1E6.
TROPICAL CYCLONE 03A IS MOVING NORTHWARD AT 5 KNOTS.  IT IS
EXPECTED TO CONTINUE SLOWLY NORTHWARD TO NORTH-NORTHWESTWARD
THROUGH 48 HOURS, INFLUENCED BY AN AREA OF WEAKENED STEERING
AND LOWER PRESSURES WITHIN THE SUBTROPICAL RIDGE.  NEARER TO
THE END OF THE FORECAST PERIOD, TC 03A IS FORECAST TO INCREASE
ITS FORWARD MOTION AND BEGIN TO SHOW SLIGHT EASTWARD TENDANCY
DUE TO INCREASED INFLUENCE OF RIDGING LOCATED TO THE EAST.
THE SYSTEM IS EXPECTED TO INTENSIFY THROUGHOUT THE FORECAST
PERIOD.  MAXIMUM SIGNIFICANT WAVE HEIGHT AT 061200Z IS 17
FEET.  REFER TO WWIO31 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION.  NEXT WARNINGS AT 062100Z9 (DTG 061951Z2),
070300Z0 (DTG 070151Z4), 070900Z6 (DTG 070751Z0) AND 071500Z3
(DTG 071351Z7).//
