REMARKS:
010300Z POSITION NEAR 35.6N 123.4E.
01AUG22. TROPICAL DEPRESSION (TD) 06W (SONGDA), LOCATED APPROXIMATELY
168 NM WEST OF KUNSAN AB, HAS TRACKED NORTH-NORTHEASTWARD AT 05
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A FULLY-EXPOSED, DEFINED LOW-LEVEL CIRCULATION (LLC)
WITH NO ASSOCIATED DEEP CONVECTION. THEREFORE THERE IS HIGH
CONFIDENCE IN THE INITIAL POSITION. A 312306Z SSMIS 91GHZ COLOR
COMPOSITE MICROWAVE IMAGE SHOWS SHALLOW BANDING WRAPPING AROUND A
BROAD, WEAKENING CENTER. THE INITIAL INTENSITY IS ASSESSED AT 25
KNOTS WITH MEDIUM CONFIDENCE. TD 06W IS LOCATED UNDER
STRONG SOUTHWESTERLY FLOW ALOFT ASSOCIATED WITH AN UPPER-LEVEL
TROUGH POSITIONED OVER THE GULF OF POHAI. THIS UNFAVORABLE
ENVIRONMENT IS DOMINATED BY CONVERGENCE ALOFT, MODERATE TO HIGH
VERTICAL WIND SHEAR AND SIGNIFICANT DRY AIR. THESE CONDITIONS WILL
PERSIST THROUGH THE FORECAST PERIOD WITH STEADY WEAKENING EXPECTED
AND DISSIPATION LIKELY BY TAU 12. THERE IS SOME UNCERTAINTY IN THE
EXACT FORECAST TRACK WITH TD 07W LOCATED ABOUT 250NM SOUTHEAST OF TD
06W'S INITIAL POSITION. THUS BINARY INTERACTION COULD OCCUR AS TD 07W
GETS ABSORBED IN THE SOUTHEASTERN PERIPHERY OF TD 06W. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR
HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 010000Z IS 10 FEET. REFER TO
TROPICAL DEPRESSION 07W (TRASES) WARNINGS (WTPN32 PGTW) FOR SIX-
HOURLY UPDATES.//
