REMARKS:
TROPICAL LOW 30U IS MOVING NORTHWEST IN THE ARAFURA SEA. THE LOW HAS
SHOWN NO
SIGNS OF PERSISTENT DEEP CONVECTION THIS EVENING.

POSITION BASED ON RADAR AND ANIMATED SATELLITE IMAGERY WITH
ASSISTANCE FROM THE
METOP-B ASCAT PASS AT 1245UTC.

DVORAK ANALYSIS: AS THE DEEP CONVECTION HAS WEAKENED, THERE IS NO
SUITABLE
DVORAK PATTERN TO APPLY TO THE CURRENT SATELLITE IMAGERY. MET IS 1.5
BASED ON A
24 HOUR W- TREND, WITH NO ADJUSTMENT. FT AND CI ARE 1.5 BASED ON MET.

WITH A REDUCED THREAT OF DEVELOPMENT OF THE SYSTEM, THIS WILL BE THE
FINAL
ISSUE OF THE TECHNICAL BULLETIN. THE SITUATION WILL CONTINUE TO BE
MONITORED.
