REMARKS:
212100Z6 POSITION NEAR 18.6S5 42.0E6.
TROPICAL CYCLONE (TC) 12S (ERNEST) LOCATED APPROXIMATELY
290 NM WEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED
SOUTHWARD AT 11 KNOTS OVER THE PAST 06 HOURS. THE WARNING
POSITION IS BASED ON 211730Z4 ENHANCED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 77 AND 90 KNOTS. RECENT ANIMATED
WATER VAPOR IMAGERY INDICATES EQUATORWARD AND POLEWARD OUTFLOW
CHANNELS CONTINUE TO PROVIDE FAVORABLE VENTILATION FOR TC 12S.
THE SYSTEM IS FORECAST TO CONTINUE TO TRACK SOUTHWARD ALONG
THE WESTERN PERIPHERY OF A MID-LEVEL STEERING RIDGE LOCATED
TO THE SOUTHEAST. TC 12S IS EXPECTED TO CONTINUE TO INTENSIFY
IN THE WARM WATERS OF THE MOZAMBIQUE CHANNEL IN AN ENVIRONMENT
OF WEAK VERTICAL SHEAR AND FAVORABLE OUTFLOW OVER THE NEXT 12
TO 24 HOURS BEFORE THE SYSTEM INTERACTS WITH LAND. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 211800Z2 IS 25 FEET. NEXT WARNINGS
AT 220900Z3 AND 222100Z7.//
