[Asia Economy Reporter Hyunju Lee] From the night of the 9th (today) to the 10th (tomorrow), the monsoon rain will fall nationwide.

The Korea Meteorological Administration forecasted on the 9th that the rain, which started in Jeju, will expand to the southern coast overnight and rain will fall in the central region by tomorrow morning. This rain is caused by a low-pressure system developed from a stationary front passing through the southern coastal area. Since the low-pressure system will not expand to the central region, precipitation amounts are expected to vary significantly by region.

Expected precipitation by tomorrow morning is up to 150mm in the southern coast of Jeollanam-do, the eastern coast of Gyeongsangbuk-do, Gyeongsangnam-do, Jeju, Ulleungdo, and Dokdo (over 200mm in the coastal areas of Gyeongsangnam-do, southern Jeju, and mountainous areas). Gangwon Yeongdong and Jeollanam-do (excluding the southern coast), and inland Gyeongsangbuk-do are expected to receive 30-80mm, while the central region excluding Gangwon Yeongdong is expected to receive 5-40mm. In particular, Jeju and the Gyeongsangnam-do coast are expected to experience very strong rain accompanied by gusts and thunder/lightning, with hourly rainfall of 50-70mm or more, and the southern coast of Jeollanam-do is expected to have very strong rain of around 30mm per hour, so caution is needed. The rain will begin to stop from the west in the afternoon tomorrow and will cease in most areas nationwide except Gangwon Yeongdong by night. The whole country will be cloudy until the 11th (the day after tomorrow), then gradually clear up at night.

The monsoon rain will start again from the morning of the 12th in Jeju. On the afternoon of the 12th, rain will expand to Chungcheongnam-do and Jeolla regions, then spread nationwide on the 13th. Warm and humid water vapor will rise to the central region, bringing heavy rain there as well. The rain falling over two days until the 14th will stop but is expected to return again in the latter half of the week. The Korea Meteorological Administration advised, "Since the intensity and movement path of the low-pressure system are very variable, please refer to the latest weather information to be announced for precipitation amounts and concentrated rainfall areas (timing)."

The heat will ease along with the monsoon rain. The daytime high temperatures are expected to be 23-33°C on the 9th and 22-28°C on the 10th. Due to humidity, the perceived temperature is expected to be about 2-3 degrees higher.
