02Z評級Low
  B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 6.5N 86.3E,
APPROXIMATELY 380 NM EAST OF COLOMBO, SRI LANKA. ANIMATED INFRARED
SATELLITE IMAGERY DEPICTS A BROAD LOW LEVEL CIRCULATION CENTER
(LLCC) ENHANCED BY A STRONG WESTERLY SURGE ALONG THE EQUATOR. A
121621Z GPM 89GHZ MICROWAVE IMAGE FURTHER DEPICTS THE BROAD LLCC
WITH LIMITED ASSOCIATED CONVECTION. THE DISTURBANCE IS IN A
FAVORABLE ENVIRONMENT WITH LOW (5-10 KNOT) VERTICAL WIND SHEAR, GOOD
DIVERGENCE ALOFT, AND VERY WARM SEA SURFACE TEMPERATURES. GLOBAL
MODELS SHOW FURTHER DEVELOPMENT IN THE NEXT 2-3 DAYS AS THE SYSTEM
TRACKS NORTHWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
15 TO 20 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 LOW.
