Actualizan Fiji y la marina, y esta ultima rectificando Track, pero igualando intensidad máxima prevista en 115 KT.

REMARKS:
162100Z POSITION NEAR 16.7S 178.0E.
TROPICAL CYCLONE (TC) 04P (EVAN), LOCATED APPROXIMATELY 95 NM
NORTH-NORTHEAST OF NADI, FIJI, HAS TRACKED SOUTHWESTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY (IR)
SHOWS AN INTENSE SYSTEM WITH DEEP CENTRAL CONVECTION WRAPPING AROUND
A RAGGED 7NM EYE.
THE CURRENT POSITION IS BASED ON THE EYE SEEN IN
THE IR, POSITIONING FIXES FROM PGTW, KNES AND PHFO, AND RADAR
IMAGERY FROM FIJI WITH HIGH CONFIDENCE. THE INTENSITY HAS CONTINUED
TO INCREASE, WITH CONGRUENT DVORAK INTENSITY ESTIMATES NOW
INDICATING 113 KNOTS FROM ALL REPORTING AGENCIES. UPPER LEVEL
ANALYSIS INDICATES A POINT SOURCE ANTICYCLONE REMAINS OVER THE
TC 04P, GIVING AMPLE RADIAL OUTFLOW WHILE THE POLEWARD OUTFLOW IS
BEING ENHANCED BY THE SUBTROPICAL JET TO THE SOUTH AND NOW LOW (5 TO
10 KNOTS) VERTICAL WIND SHEAR (VWS). TC 04P CONTINUES TO TRACK ALONG
THE NORTHWESTERN PERIPHERY OF A DEEP LAYERED SUBTROPICAL RIDGE
(STR), LOCATED TO THE SOUTHEAST OF FIJI. A MID-LATITUDE TROUGH,
CURRENTLY OFF THE COAST OF EASTERN AUSTRALIA, IS FORECAST TO ERODE
THE WESTERN PERIPHERY OF THE STR, CAUSING THE STR TO BECOME MORE
MERIDIONALLY ALIGNED, ALLOWING TC 04P TO TRACK SOUTHWARD BEYOND TAU
24. A SLOW WEAKENING TREND THROUGH TAU 48 IS FORECAST AS VWS OFFSETS
THE FAVORABLE OUTFLOW FROM THE MID-LATITUDE TROUGH. BEYOND TAU 48,
STRONGER VWS AND DECREASING SEA SURFACE TEMPERATURES WILL ACCELERATE
THE WEAKENING TREND OBSERVED THROUGH THE REMAINDER OF THE FORECAST
PERIOD. WITH THE EXCEPTION OF JGSM AND EGRR, MODEL GUIDANCE IS IN
GOOD AGREEMENT, WITH EGRR AND JGSM BOTH ERRONEOUSLY DRIVING THE
SYSTEM INTO THE MID-LATITUDE TROUGH. THE FORECAST IS SLIGHTLY FASTER
AND EAST OF THE MULTI-MODEL CONSENSUS TO OFFSET THE EGRR AND JGSM
SOLUTIONS. DUE TO THE TIGHT AGREEMENT AMONG THE OTHER CONSENSUS
MEMBERS, FORECAST CONFIDENCE REMAINS HIGH. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 161800Z IS 40 FEET. NEXT WARNINGS AT 170900Z AND 172100Z.//

Su centro comienza a quedarse libre de nubosidad, ahora será mucho más fácil observar su trayectoria, aunque no penetre directamente en Fiji, los efectos van a ser devastadores.

Su centro abandona definitivamente Fiji, y comenzará a degradarse muy lentamente (115KT) dirección sur, camino de Nueva Zelanda.

Milagrosamente no se han producido víctimas mortales en Fiji, aunque van a tardar mucho en recuperarse de los devastadores efectos de Evan.

Samoa sigue sumida en el caos, y el número de víctimas mortales se eleva por el momento a cuatro.
