REMARKS:
302100Z6 POSITION NEAR 16.6S3 42.0E6.
TROPICAL CYCLONE (TC) 08S, LOCATED APPROXIMATELY 140 NM EAST OF
MOZAMBIQUE IN THE MOZAMBIQUE CHANNEL, HAS TRACKED WEST-SOUTHWESTWARD
AT 05 KNOTS DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED
ON 301730Z4 ENHANCED INFRARED AND RECENT MICROWAVE SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 35 KNOTS. RECENT MICROWAVE IMAGERY DEPICTS
INCREASING ORGANIZATION, WHILE ANIMATED INFRARED SATELLITE IMAGERY
SHOWS FAVORABLE POLEWARD OUTFLOW. THE SYSTEM IS EXPECTED TO TRACK
WEST-SOUTHWESTWARD THROUGH THE FORECAST PERIOD ALONG THE NORTHERN
EDGE OF THE LOW TO MID-LEVEL SUBTROPICAL STEERING RIDGE. THE SYSTEM
SHOULD INTENSIFY AT A CLIMATOLOGICAL RATE BEFORE MAKING LANDFALL
NEAR THE 24 HOUR POINT. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
NGPS, NCEP AVIATION (AVN), AND BETA ADVECTION MODELS ARE IN GOOD
AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE
AND A CONSENSUS OF ALL THE AVAILABLE DYNAMIC AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 301800Z2 IS 10 FEET. NEXT WARNINGS AT
310900Z3 AND 312100Z7.//

REMARKS:
310900Z3 POSITION NEAR 16.2S9 41.1E6.
TROPICAL CYCLONE (TC) 08S, LOCATED APPROXIMATELY 70 NM EAST OF
MOZAMBIQUE IN THE MOZAMBIQUE CHANNEL, HAS TRACKED WESTWARD AT 05
KNOTS DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED
ON 310530Z2 VISIBLE AND ENHANCED INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 30 AND 35 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
SIGNIFICANT DEEP CONVECTION ASSOCIATED WITH THE SYSTEM AND SEVERAL
RAINBANDS. THE SYSTEM IS EXPECTED TO TRACK WESTWARD ALONG THE LOW TO
MID-LEVEL SUBTROPICAL STEERING RIDGE. THE SYSTEM IS EXPECTED TO
INTENSIFY AT A CLIMATOLOGICAL RATE BEFORE MAKING LANDFALL
IN THE NEXT 12 TO 24 HOURS. THE AVAILABLE DYNAMIC AIDS CONSISTING OF
NGPS, NCEP AVIATION (AVN), AND BETA ADVECTION MODELS ARE IN FAIR
AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE
AND A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 310600Z0 IS 09 FEET. NEXT WARNINGS AT 312100Z7 AND
010900Z0. JUSTIFICATION FOR COR: CORRECTED MANOP HEADER.//

REMARKS:
312100Z7 POSITION NEAR 16.1S8 40.1E5.
TROPICAL CYCLONE (TC) 08S (DELFINA), LOCATED APPROXIMATELY 18 NM
EAST OF MOZAMBIQUE OVER THE MOZAMBIQUE CHANNEL, HAS TRACKED WEST AT
06 KNOTS DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED
ON 311730Z5 ENHANCED INFRARED SATELLITE IMAGERY AND A 311725Z9 SSM/I
PASS. THE WARNING INTENSITY IS BASED ON DVORAK CURRENT INTENSITY
ESTIMATES OF 3.5 (55 KTS) AND THE SSM/I PASS DEPICTING POSSIBLE EYE
FEATURE DEVELOPMENT. A MID-LEVEL RIDGE EXTENDING OVER THE MOZAMBIQUE
CHANNEL SHOULD PROVIDE A WESTWARD STEERING ENVIRONMENT THROUGH THE
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 311800Z3 IS 10 FEET.
NEXT WARNING AT 010900Z0.//
