我也無言了, 之前還看好發展, 現在還沒命名就突然減弱...
看看JTWC這一報
TROPICAL CYCLONE (TC) 19S, LOCATED APPROXIMATELY 270 NM NORTH-NORTHWEST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 13 KNOTS DURING THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS TC 19S HAS WEAKENED SIGNIFICANTLY IN THE PAST 12 HOURS AND NOW HAS MINIMAL ASSOCIATED DEEP CONVECTION. ADDITIONALLY, A 071110Z SSMIS DEPICTS A VERY WEAK, FULLY EXPOSED LOW LEVEL CIRCULATION CENTER, FROM WHICH THE INITIAL POSITION WAS BASED. THE INITIAL INTENSITY WAS ON THE LOWER SIDE OF THE KNES AND PGTW 25 TO 35 KNOT DVORAK ESTIMATES BECAUSE OF THE WEAK CONVECTIVE SIGNATURE IN MICROWAVE IMAGERY. TC 19S IS EXPECTED TO CONTINUE TO WEAKEN UNDER HIGH VERTICAL WIND SHEAR, BUT COULD POTENTIALLY REDEVELOP AS IT TRACKS UNDER THE SUBTROPICAL RIDGE AXIS TO THE SOUTH. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
原來風切作怪, 對流被切走, LLCC嚴重外露
不過未來還有可能重新發展
