Tropical Cyclone Enok

102100Z POSITION NEAR 20.1S 64.2E.
TROPICAL CYCLONE (TC) 13S (ENOK), LOCATED APPROXIMATELY 460 NM EAST-
NORTHEAST OF LA REUNION, HAS TRACKED SOUTHEASTWARD AT 19 KNOTS OVER
THE PAST SIX HOURS. TC 13S CONTINUES TO TRACK RAPIDLY SOUTHEASTWARD
IN THE STRONG GRADIENT BETWEEN RIDGING TO THE NORTHEAST AND TROUGHING
ASSOCIATED WITH THE REMNANTS OF TC 10S TO THE SOUTHWEST. THIS MOTION
IS EXPECTED TO CONTINUE THROUGH THE FORECAST PERIOD, WITH SOME REDUC-
TION IN FORWARD SPEED AS THE REMNANT LOW OF 10S FILLS AND ASSOCIATED
TROUGHING DISSIPATES. THE STORM IS EXPECTED TO WEAKEN VERY SLOWLY
OVER THE NEXT 48 HOURS AS FAVORABLE EQUATORWARD OUTFLOW AND ENHANCED
POLEWARD OUTFLOW ASSOCIATED WITH A DEVELOPING UPPER LEVEL LOW TO THE
SOUTH OF THE STORM WORK TO OFFSET THE NEGATIVE IMPACTS OF DECREASING
SEA SURFACE TEMPERATURES AND DRY AIR ENTRAINMENT. THE STORM IS EXPEC-
TED TO BEGIN EXTRATROPICAL TRANSITION BETWEEN TAU 36 AND TAU 48 DUE
TO INCREASING INTERACTION WITH THE MID-LATITUDE FLOW PATTERN TO THE
SOUTH. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 101800Z IS 15 FEET.
