REMARKS:
020300Z5 POSITION NEAR 23.0S5 36.9E8.
TROPICAL CYCLONE (TC) 19S (JAPHET), LOCATED APPROXIMATELY 85 NM
EAST OF THE MOZAMBIQUE COAST, HAS TRACKED NORTHWESTWARD AT 05 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 012330Z9
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 KNOTS. THE MID-LEVEL
HAS BUILT IN OVER THE SOUTH AFRICAN CONTINENT AND IS EXPECTED TO
GUIDE TC 19S NORTHWESTWARD THROUGH THE FORECAST PERIOD. TC 19S IS
EXPECTED TO CONTINUE TO WEAKEN AS IT APPROACHES THE MOZAMBIQUE COAST
AS THE RESULT OF DRY AIR ENTRAINMENT AND CONTINUED WEAK UPPER LEVEL
POLEWARD OUTFLOW. THE AVAILABLE DYNAMIC AIDS INCLUDING NOGAPS, GFDN,
AFWA MM5 AND NCEP AVIATION (AVN) ARE IN AGREEMENT WITH THIS
SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE AND A CONSENSUS OF
THE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 020000Z2 IS 22
FEET. NEXT WARNINGS ARE AT 021500Z8 AND 030300Z6. RELEASED BY CAPT
LEEJOICE, USAF.//
