REMARKS:
280300Z3 POSITION NEAR 23.2S7 37.8E8.
TROPICAL CYCLONE (TC) 19S (JAPHET), LOCATED APPROXIMATELY 128 NM
EAST OF THE MOZAMBIQUE COAST, HAS TRACKED SOUTH-SOUTHWESTWARD AT 08
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
272330Z7 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 65 AND 77 KNOTS. TC 19S
IS FORECAST TO TRACK SOUTHWEST THROUGH 24 HOURS TOWARDS A WEAKNESS
IN THE MID-LEVEL SUBTROPICAL RIDGE SOUTHEAST OF THE SYSTEM.
AFTERWARDS, TC 19S IS EXPECTED TO REMAIN QUASISTATIONARY IN THE
WEAKNESS UNTIL THE MID-LEVEL RIDGE OVER CENTRAL AFRICA PROPAGATES
EASTWARD AND PUSHES TC 19C EQUATORWARD FOR THE REMAINDER OF THE
FORECAST PERIOD. TC 19S FORECAST TO INTENSIFY AT A CLIMATOLOGICAL
RATE UNDER A FAVORABLE ENVIRONMENT UNTIL THE SYSTEM TRACKS
EQUATORWARD AT THE END OF THE FORECAST PERIOD AND ENCOUNTERS SOME
VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS INCLUDING NOGAPS,
GFDN, UKMET SPECTRAL (EGRR) AND NCEP AVIATION (AVN) ARE IN FAIR
AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE
AND A BLEND OF THE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
280000Z0 IS 15 FEET. NEXT WARNINGS AT 281500Z6 AND 010300Z4.
REFER TO TROPICAL CYCLONE  20S (GRAHAM) WARNINGS (WTXS32 PGTW)
FOR TWELVE-HOURLY UPDATES. RELEASED BY CAPT KENDALL, USAF.//
