REMARKS:
260300Z1 POSITION NEAR 17.4N2 67.3E6.
TROPICAL CYCLONE 01A HAS DRIFTED WEST-NORTHWESTWARD AT 02 KTS DURING
THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 252330Z5
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON
CURRENT INTENSITY ESTIMATES OF 55 KNOTS AND 77 KNOTS. ENHANCED
INFRARED ANIMATION DEPICTS CONSIDERABLE WEAKENING OF THE CONVECTION
NEAR THE LOW-LEVEL CIRCULATION CENTER (LLCC). THE MAJORITY OF THE
DEEP CONVECTION REMAINS DOWNSHEAR TO THE WEST OF THE LLCC. TC 01A IS
FORECAST TO BEGIN TRACKING INCREASINGLY NORTHWARD AFTER THE 12 HOUR
PERIOD. TC 01A IS EXPECTED TO WEAKEN THROUGH THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 260000Z8 IS 26 FEET. REFER TO
WWIO30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT
260900Z7, 261500Z4, 262100Z1 AND 270300Z2.//
