Re: WPAC: Tropical Depression (INVEST 99W)
JMA forecasting this to become a tropical storm between muifa and merbok but i don't see anything significant. this should come close to japan but we will see if it develops...

Re: WPAC: Tropical Depression (INVEST 99W)
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 30.5N
143.0E, IS NOW LOCATED NEAR 31.6N 140.9E, APPROXIMATELY 275 NM NORTH-
NORTHWEST OF CHICHI-JIMA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
AND A 032347Z AMSU MICROWAVE IMAGE DEPICT A WELL-DEFINED, LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH MINIMAL DEEP CONVECTION. THE LLCC HAS
DEVELOPED UNDER AN UPPER-LEVEL LOW AND, BASED ON AMSU TEMPERATURE
ANOMALY CROSS-SECTIONS, IS SUBTROPICAL IN NATURE AND DOES NOT HAVE A
WARM CORE. THE TOTAL PRECIPITABLE WATER LOOP SHOWS AN ELONGATED
SIGNATURE BUT DOES INDICATE THAT THE SYSTEM HAS STARTED A MOISTENING
PHASE. A 032359Z ASCAT PASS DEPICTS 10- TO 15- KNOT CENTRAL WINDS
WITH STRONGER 20- TO 25- KNOT WINDS ALONG THE NORTHERN PERIPHERY.
UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED BENEATH A
TROUGH IN AN AREA WITH MODERATE TO STRONG, NORTHERLY VERTICAL WIND
SHEAR (20 TO 30 KNOTS). MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. THE UPPER LEVEL ENVIRONMENT REMAINS UNFAVORABLE,
BUT BASED ON THE WELL-DEFINED LLCC AND ASSOCIATED WINDS, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
chances to develop decreasing though.
