TOMORROW MORNING (SAT): Dissipated at sea...about 516 SSE of Tokyo, Japan [8AM AUG 13: 31.4N 141.8E @ 30kph].
Maximum Sustained Winds (1-min. avg) are near 45 km/hr (25 knots) with higher gusts. 13W is a weak Tropical Depression (TD) on the Saffir-Simpson Tropical Cyclone Scale. This system will dissipate within the next 12 to 24 hours.

Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
EFFECTS & HAZARDS SUMMARY
Important Note: Please keep in mind that the above forecast outlook, extended forecast, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
13W's (UNNAMED) circulation no longer carrying any thick-rain cloud convection...just an exposed low-level circulation center with a swirl of low clouds rotating counter-clockwise. Below is the summary of the storm's parts and its hazards affecting specific areas:
DISSIPATING RAINBANDS - over water (Western Pacific Ocean)...not affecting any islands or land areas. Tropical Depression Conditions w/ moderate to strong winds (25-61 kph) will be expected along these bands (click here to know more about Rainbands).
12-18HR TOTAL RAINFALL ACCUMULATION - from 1 up to 5 mm (low rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of up to 10 mm (low) along areas near the center of 13W. (click to open NOAA's eTRaP graphic).

DEEP CONVECTION. THE SYSTEM IS STRIPPED OF VERTICAL STRUCTURE AND
IS NOW IN A WEAK STEERING PATTERN NORTH OF THE SUBTROPICAL RIDGE IN
COOL WATERS (BELOW 26 CELSIUS). IT IS EXPECTED TO DISSIPATE AS A
SIGNIFICANT TROPICAL CYCLONE OVER WATER IN THE NEXT 12 HOURS. THIS
