REMARKS:
070900Z POSITION NEAR 19.4S 66.5E.
TROPICAL CYCLONE 12S (FUNANI), LOCATED APPROXIMATELY 502 NM EAST
OF PORT LOUIS, MAURITIUS, HAS TRACKED SOUTHEASTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS A THICK EYEWALL SURROUNDING A PINHOLE EYE. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE IN THE MSI
IMAGERY. THE INITIAL INTENSITY IS BASED ON A 070455Z SATCON ESTIMATE
OF 107 KTS AND IS BELOW THE PGTW AND KNES DVORAK CURRENT INTENSITY
ESTIMATES OF T6.0 (115 KTS). UPPER LEVEL ANALYSIS INDICATES THE
SYSTEM IS IN AN AREA WITH LOW (5-10 KNOT) VERTICAL WIND SHEAR (VWS)
AND ROBUST RADIAL OUTFLOW WITH A STRONG POLEWARD BIAS THAT IS
ALLOWING FOR CONTINUED INTENSIFICATION. TC 12S IS TRACKING OVER WARM
WATERS (30 CELSIUS) ALONG THE WESTERN PERIPHERY OF A DEEP-LAYER
SUBTROPICAL RIDGE (STR) TO THE EAST. TC 12S WILL ACCELERATE TO THE
SOUTHEAST THROUGHOUT THE FORECAST IN RESPONSE TO AN UPPER LEVEL
TROUGH APPROACHING FROM THE SOUTHWEST. POLEWARD OUTFLOW WILL
INCREASE FURTHER AS TC 12S TAPS INTO THE APPROACHING MIDLATITUDE
TROUGH, ALLOWING FOR CONTINUED INTENSIFICATION TO 115 KTS BY TAU 12.
AFTER TAU 24, INCREASING VWS AND DECREASING SSTS WILL CAUSE GRADUAL
WEAKENING. BY TAU 48, TC 12S WILL BEGIN EXTRATROPICAL TRANSITION,
EVENTUALLY BECOMING A STRONG STORM-FORCE COLD CORE LOW WITH AN
EXPANDING WIND FIELD BY TAU 72. MODEL GUIDANCE IS IN TIGHT
AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC TRACK FORECAST.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070600Z IS 25 FEET. NEXT WARNINGS
AT 071500Z, 072100Z, 080300Z AND 080900Z. REFER TO TROPICAL CYCLONE
13S (GELENA) WARNINGS (WTXS32 PGTW) FOR SIX-HOURLY UPDATES.//
