Rain Forecasted on the 14th-15th in Jeonnam, Southern Jeonbuk, Gyeongnam, and Southern Gyeongbuk Regions

[Asia Economy Reporter Han Jinju] Due to the indirect influence of Typhoon 'Chantu' (No. 14), more than 500mm of heavy rain will pour over Jeju for three days starting today.

On the 13th, the Korea Meteorological Administration (KMA) forecasted very heavy rain of 30-50mm per hour in Jeju today, and 50-70mm per hour on the 14th and 15th.

The KMA explained, "The rain cloud band developing over the southern sea of Jeju Island is gradually moving northward at 30 km/h, and the rain will intensify from daytime."

As a strong cloud band forms near Jeju, a large amount of concentrated rainfall is expected on the 14th and 15th, so caution is needed for rain damage. The KMA issued a heavy rain advisory for Jeju's mountainous area at 9 a.m. and for the southern and eastern parts of Jeju at 10 a.m. on the same day.

From the night of the 13th, starting from the southern coast of Jeollanam-do, occasional rain is expected between the 14th and 15th in the Jeollanam-do region, southern Jeollabuk-do, Gyeongsangnam-do, and southern Gyeongsangbuk-do. In the Yeongdong region of Gangwon-do, weak rain of less than 5mm is expected until this morning due to the easterly wind.

Expected rainfall until the 15th is ▲Jeju Island 100-300mm (over 500mm in some areas) ▲Jeollanam-do region and southern coast of Gyeongsangnam-do 20-80mm (over 120mm in some parts of Jeollanam-do southern coast) ▲Gyeongsangnam-do (excluding southern coast), southern Jeollabuk-do, and southern Gyeongsangbuk-do 10-40mm.

Due to the indirect influence of the typhoon, from noon on the 13th, winds of 10-16 m/s with maximum gusts exceeding 20 m/s will blow very strongly in Jeju and the southern coast of Jeollanam-do.

On the 16th and 17th, under the influence of Typhoon Chantu, very strong rain along with strong winds will occur mainly in Jeju and the southern regions. Typhoon Chantu is expected to make landfall south-southeast of Shanghai in the afternoon of the 13th, stay for three days, and then make landfall west of Seogwipo in the early morning of the 17th. As of 3 a.m. on the 13th, the typhoon's central pressure is 950 hPa, maximum central wind speed is 43 m/s, and the radius of strong winds is 280 km, making it a very strong typhoon.

The KMA urged, "On the 16th and 17th, very heavy rain and strong winds are expected mainly in Jeju and the southern regions, and very strong winds and very high waves are also expected in most maritime areas. Small vessels should evacuate to safe locations."

From the night of the 16th to the afternoon of the 17th, rain will fall across most parts of the country, and rain is also forecast nationwide on the afternoon of the 21st, during the Chuseok holiday. As the typhoon stalls and then moves while intensifying, weather variability will be very high.

Han Sang-eun, a meteorological expert at the KMA, explained, "Based on the current forecasted path, the typhoon is expected to move near Jeju or the southern coast, continuously supplying moisture from the south wind while cold and dry air is positioned over Korea. Therefore, although Jeju is not in the direct influence zone of the typhoon, it will receive heavy rain. The central region is farther from the influence zone, so rainfall is expected to be relatively less."
