According to the Korea Meteorological Administration on the 13th, due to the influence of a stationary front, very heavy rain accompanied by gusty winds, thunder, and lightning will fall in the southern regions and Jeju Island until the 15th.

Expected rainfall from the 13th to the 15th is ▲ over 300mm in the mountainous areas of Jeju (over 200mm in many places except northern Jeju) ▲ over 150mm in many places along the southern coast of Gyeongnam ▲ 60 to 120mm (over 200mm in many places) along the southern coast of Jeonnam ▲ 50 to 100mm in Busan, Ulsan, Gyeongnam, Gwangju, Jeonnam, and Jeju.

On the 14th, 5 to 20mm of rain is expected in Gangwon Yeongdong, and about 10 to 40mm in Daejeon, Sejong, southern Chungnam, and central to southern Chungbuk. The expected rainfall in areas with rain on the 14th and 15th is ▲ 30 to 80mm in Daegu, southern Gyeongbuk, and southern Jeonbuk ▲ 20 to 60mm in northern Jeonbuk ▲ 5 to 20mm in Gangwon Yeongdong ▲ 10 to 40mm in northern Gyeongbuk, Ulleungdo, and Dokdo.

Attention should be paid as the timing of concentrated rainfall varies by region. In Jeju Island, heavy rain of about 30 to 50mm per hour will pour from the night of the 13th to the afternoon of the 14th, and again from late night on the 14th to the morning of the 15th. In the mountainous areas of Jeju, a deluge of 50 to 70mm per hour is expected.

In the Gyeongnam area, heavy rain is expected from early morning to morning on the 14th, and again from late night on the 14th to the morning of the 15th. Along the southern coast of Gyeongnam, 30 to 50mm per hour is expected, and in Busan, 30mm per hour. Along the southern coast of Jeonnam, 30 to 50mm per hour will fall from the night of the 13th to the morning of the 14th, and again from late night on the 14th to the morning of the 15th. In the Gyeongbuk area, heavy rain of 20 to 30mm per hour will pour from early morning to morning on the 14th.

Due to the stationary front, a strong southern wind brings in a large amount of moisture, causing very heavy rain and concerns about rain damage mainly in Jeju Island, the southern coast of Jeonnam, and the southern coast of Gyeongnam until the 15th.

The Korea Meteorological Administration advised, "Since rain falling in valleys and upstream rivers can cause sudden flooding, camping should be avoided, and access to riverside walking trails, underpasses, etc., should be prohibited as isolation may occur." They also warned to be cautious of landslides, soil erosion, facility collapses, reservoir collapses, and flooding due to river embankment failures.

Showers will fall in the Seoul metropolitan area, Gangwon Yeongseo, and northern Chungcheongbuk-do from the afternoon to night on the 14th. Expected rainfall on the 14th is ▲ 5 to 20mm in Seoul, Incheon, and Gyeonggi ▲ 5 to 20mm in Gangwon Yeongseo ▲ 5 to 20mm in northern Chungnam and northern Chungbuk.

Localized showers may be intense, accompanied by gusty winds, thunder, and lightning, with very strong showers of 20 to 30mm per hour in some places.

The Korea Meteorological Administration stated, "Visibility may rapidly decrease, roads may become slippery or flooded, so special attention to traffic safety is required. Since the ground is weakened by heavy rain, even small amounts of showers can cause damage, so caution is needed regarding soil erosion and related hazards."

The lowest temperature on the morning of the 14th is forecast to be 20 to 24 degrees Celsius, and the highest temperature during the day is 23 to 31 degrees Celsius. In areas where rain or showers fall, temperatures will rise again during the day after the rain stops, making it hot.

Heatwave warnings are in effect for the Seoul metropolitan area, inland Gangwon, inland Chungcheong, and parts of northern inland Gyeongbuk, where the highest perceived temperature will rise above 33 degrees Celsius, making it very hot. Other regions will also see the highest perceived temperature rise up to 31 degrees Celsius.

On the 14th, from morning to afternoon, Jeju Island (mid-mountain and mountainous areas) will experience very strong gusts with instantaneous wind speeds exceeding 20m/s, and over 25m/s in mountainous areas. Along the southern coast and other parts of Jeju Island, instantaneous wind speeds of over 15m/s will also be strong.

From the morning of the 14th, the southern offshore waters of Jeju Island will have very strong winds with speeds of 10 to 16m/s, and waves will rise very high at 1.5 to 3.5 meters, so vessels engaged in navigation or fishing should exercise caution.
