如果奧莉薇復活,名字一樣嗎?
還是由西太重新命名?

JTWC 01Z評級Low
      (1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR
20.0N 163.8E, APPROXIMATELY 160 NM WEST-NORTHWEST OF WAKE ISLAND.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 232306Z 89GHZ GMI
MICROWAVE IMAGE DEPICT A COMPACT DISORGANIZED SYSTEM WITH LIMITED
CONVECTION WITH TURNINGIN THE LOWER LEVELS. THE MOST RECENT 231018Z
PARTIAL ASCAT PASS REVEALED 15- TO 20-KNOT WINDS IN THE NORTHEAST
QUADRANT WITH TROUGHING IN THE LOWER LEVELS. UPPER LEVEL ANALYSIS
INDICATES A MODERATELY FAVORABLE ENVIRONMENT WITH MODERATE SHEAR (15-
25KTS) AND MODERATE POLEWARD DIVERGENCE. SEA SURFACE TEMPERATURES IN
THE VICINITY ARE FAVORABLE, BETWEEN 29-31 CELSIUS. GLOBAL MODELS
INDICATE POSSIBLE DEVELOPMENT MOVING NORTH WITH SUBTROPICAL
CHARACTERISTICS IN THE NEXT 36-72 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

JMA 04Z再度升格TD
18092512.png

JTWC 06Z提升評級至Medium
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 20.4N 161.8E, IS NOW LOCATED NEAR 21.3N 157.5E, APPROXIMATELY
526 NM WEST OF WAKE ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
AND A 250248Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT BROAD BANDING
WRAPPING INTO A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC).
UPPER LEVEL ANALYSIS INDICATES LOW TO MODERATE (15-20KTS) VERTICAL
WIND SHEAR AND FAVORABLE OUTFLOW. A 241105Z ASCAT PASS REVEALS A
MORE SYMMETRIC CIRCULATION WITH 20-25 KNOT WINDS IN THE NORTHEAST
QUADRANT. SEA SURFACE TEMPERATURES (29-31 CELSIUS) REMAIN SUPPORTIVE
FOR FUTURE DEVELOPMENT. GLOBAL MODELS REMAIN IN THE GENERAL
AGREEMENT ON 93W'S POLEWARD TRAJECTORY, BUT VARY ON TIME FRAMES AND
INTENSITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
