[Asia Economy Reporter Han Jinju] On the 25th and 26th, heavy rain accompanied by thunder and lightning will fall nationwide. Jeju and the southern coast are expected to experience strong winds along with heavy rain of 120mm and hourly rainfall of 30-50mm or more.

On the 24th, the Korea Meteorological Administration held an occasional forecast briefing and announced that due to the influence of a low-pressure system originating from southern China, rain will begin in the Jeolla region and Jeju Island from the evening of the 25th and expand nationwide by the early morning of the 26th.

Forecaster Lee Kwang-yeon explained, "Due to the influence of the low-pressure system coming from the south, hot and humid air will flow into the Korean Peninsula until the early morning of the 26th, and nationwide precipitation is expected. After the low-pressure system passes, a north wind will move southward, causing temperatures to drop significantly between the 26th and 27th, and large daily temperature differences with clear weather will continue until the 29th."

By the 26th, heavy rain of 50-120mm is expected in Jeju Island (excluding the northern part), the southern coast, and around Jirisan Mountain, with more than 300mm in the mountainous areas of Jeju. The Chungcheong region, southern areas, and northern Jeju will receive 20-70mm, while the metropolitan area and Gangwon Province will see about 5-40mm. The rain will end starting from the central region during the daytime of the 26th and nationwide by the evening.

Hot and humid air is flowing in from the south, and due to the terrain, precipitation is expected to concentrate in Jeju and the southern coast. In Jeju and the southern coast, heavy rainfall of 30-50mm per hour is expected between the early morning and morning of the 26th, so caution is needed against flooding and inundation. Strong winds with maximum instantaneous speeds exceeding 20 meters per second will also blow, so facility management should be careful.

Forecaster Lee said, "Cloud bands will develop very high mainly around Jeju and the southern coast, accompanied by thunder, lightning, and in some places, gusts of wind. Heavy rain warnings and strong wind and high wave warnings are expected to be issued for most areas of Jeju and the southern coast from the early morning of the 26th."

Depending on the extent to which hot and humid water vapor moves northward, precipitation in the central region may increase. If unstable air stagnates, the amount and duration of rainfall in Jeju and southern regions may also increase. Forecaster Lee explained, "The precipitation forecast for the Chungcheong region and southern areas is 20-70mm, but if the low-pressure system's path shifts just 10-20km north or south, the expected precipitation could increase to 20-70mm even in the southern part of Gyeonggi Province."

After the rain stops, under the influence of a mobile high-pressure system, clear and sunny weather with large daily temperature differences will continue. Strong north winds will blow, and cold air will descend, causing morning temperatures to drop significantly on the 27th. The nationwide morning low temperatures on the 27th are expected to be between 8 and 15 degrees Celsius, with Seoul expected at 10 degrees. There is also a possibility of yellow dust blowing on the west coast.

Rain is also expected on Friday the 29th. Forecaster Lee said, "As the pressure system changes and a low-pressure system passes through the south, rain is likely mainly in the southern part of Jeju. There is a lot of water vapor in the southern region, causing high variability, and the mid-term forecast suggests the precipitation area may expand."
