The National Center for Hydro-Meteorological Forecasting (NCHMF) said that the low-pressure system over the southeastern part of the northern East Sea strengthened into a tropical depression on the afternoon of August 4.
At 1 p.m., the center of the tropical depression was located at about 17 degrees North latitude and 119.7 degrees East longitude, over the southeastern waters of the northern East Sea.
Maximum sustained winds near the center reached Force 6 (39-49 kilometers per hour), with gusts up to Force 8. The system was moving northwest at 5-10 kilometers per hour.
