Rain is expected over most of the country this Friday to Saturday, with heavy rain pounding mainly the western side of the Korean Peninsula. After the rain stops, clear weather will continue for a while. The heat wave that persisted recently will retreat, ushering in cool autumn weather.

The Korea meteorological Administration said at a regular forecast briefing on the 18th, "Precipitation will begin in western regions from the afternoon of the 19th and expand nationwide," and "From the early morning to morning of the 20th, heavy rain will fall mainly along the West Sea coast."

The Korea meteorological Administration forecast 10–60 mm of rain nationwide on the 19th–20th. It expected more than 80 mm along the southern Chungnam West Sea coast and the Jeonbuk West Sea coast. As these areas are forecast to see 30 mm per hour, rain will pound hard. On Saturday the 20th, most areas will see the rain stop in the morning, but the Gangwon East Sea coast could continue to see rain.

Starting Sunday the 21st, the weather will be clear and cool. The Korea meteorological Administration said, "Daytime highs next week will be around 26 degrees in central regions and around 27 degrees in southern regions, near normal," and "Morning or nighttime lows could drop below 20 degrees." This weather will continue for the time being through Wednesday the 24th, when there is a chance of rain.

The "heat wave" that raged this summer has retreated. An official at the Korea meteorological Administration said, "A heat wave advisory is issued when an apparent temperature of 33 degrees or higher is expected to persist for two or more days, but for now, the likelihood of high temperatures continuing for several days to several weeks has diminished," and noted, "We have entered a period when cold air descends from the north."

However, three tropical depressions (TD), also called "seeds of typhoons," have simultaneously developed over the seas near the Philippines and Japan adjacent to Korea. This could act as a variable for a rise in temperatures later.
