Typhoon Hinnamnor to Make Landfall on South Gyeongsang Namhaean Coast on the 6th... The Strongest Typhoon in History Approaches

Expected to pass along the southern coast of the Korean Peninsula
Changed course northward to land on the southern coast of Gyeongnam
Heavy rainfall of up to 350mm expected in many parts of Jeju from the 2nd to 4th
Strongest impact on southern Gyeonggi, Chungcheong, southern regions, and Jeju on the 5th to 6th

Meteorologists at the Korea Meteorological Administration's National Typhoon Center are analyzing a typhoon.

[Asia Economy Reporter Han Jinju] Typhoon Hin Nam No is set to make landfall on the southern coast of Gyeongnam on the 6th. The forecast has been revised as the typhoon's path shifted northward, now expected to pass through Busan and the southern coastal areas.

The Korea Meteorological Administration held an unscheduled briefing on the 2nd, announcing that Typhoon Hin Nam No will make landfall on the Korean Peninsula on the 6th, with potential damage from heavy rain and strong winds on the 5th and 6th. The expected rainfall amounts between the 2nd and 4th, before the typhoon's landfall, have been increased, and the forecasted precipitation areas have also changed.

Forecaster Woo Jin-gyu explained, "The typhoon's path has shifted slightly, but the expected impact from rain and wind has not changed significantly. Both areas affected by the strong rainbands before the typhoon's arrival and those impacted by the typhoon's core can be at risk."

As of 9 a.m., Typhoon Hin Nam No is moving northwest about 560 km southeast of Taiwan, with a central pressure of 935 hPa and maximum instantaneous wind speed of 49 m/s. It is expected to pass about 500 km south-southwest of Seogwipo at 9 a.m. on the 5th and make landfall about 90 km southwest of Busan at 9 a.m. on the 6th. By 9 a.m. on the 7th, it is forecasted to transition into an extratropical cyclone over the sea southwest of Sapporo, Japan.

Hin Nam No is as intense as the devastating typhoons 'Sarah' and 'Maemi.' No typhoon with such a low central pressure has ever made landfall on the Korean Peninsula. The central pressure of Hin Nam No is expected to reach between 940 and 950 hPa, making it the strongest typhoon to make landfall on the peninsula based on central pressure. The lower the central pressure, the stronger the cyclone, classifying it as a powerful typhoon. Typhoon Sarah in 1959 had a central pressure of 991.5 hPa and was relatively weak but caused significant damage, while Typhoon Maemi in 2003 had a central pressure of 954 hPa, ranking as the second strongest on record.

The wind intensity is also expected to be very strong, raising concerns about increased typhoon damage. On the 5th, when Hin Nam No passes south-southwest of Seogwipo, the maximum instantaneous wind speed is expected to reach 51 m/s, and on the 6th near the southwest sea of Busan, it is forecasted at 43 m/s. Typhoon Maemi recorded a daily maximum wind speed of 51 m/s and instantaneous maximum wind speeds exceeding 60 m/s in the Jeju Gosan area.

Forecaster Woo said, "Typhoon damage and impact are influenced by social environments and flood control industries, making precise damage prediction difficult. However, the fact that no typhoon with such a low central pressure has made landfall before is concerning. At points where high tide and low tide intersect and sea levels rise, storm surges, backflows, and storm tides caused by the typhoon can inundate inland coastal areas, so thorough preparation is necessary."

Rain and wind are expected to be strongest on the 5th and 6th, when the typhoon makes landfall. Heavy precipitation and strong winds are forecast mainly for southern Gyeonggi, Chungcheong, southern regions, and Jeju Island, while the Seoul metropolitan area and Gangwon Province will be affected by strong rain clouds. Previously, the Seoul metropolitan area was expected to be largely unaffected, but with the typhoon's path shifting northward, the southern part of Gyeonggi has now been included in the affected area.

From the 2nd to the 4th, Jeju Island could receive over 350 mm of rain, with 100 to 250 mm expected. The southern coast of Jeollanam-do and coastal areas of Gyeongnam are forecast to receive 50 to 150 mm, southern Gyeongbuk, inland Gyeongnam, Jeonnam (from the 3rd), the Seoul metropolitan area, and the five western islands are expected to see 20 to 70 mm from the 4th. Rainfall of 10 to 50 mm is expected in Yeongdong, northern Gyeongbuk, Chungcheong, Jeonbuk, Ulleungdo and Dokdo from the 3rd, and Yeongseo on the 4th.

Forecaster Woo explained, "The typhoon will be closest to Jeju Island in the early morning of the 6th, and there is a possibility it could arrive earlier, by the night of the 6th. It is expected to make landfall on the southern coast of Gyeongnam between dawn and morning on the 6th. Instantaneous wind speeds exceeding 50 m/s are possible mainly around Jeju Island, the southern coast, and the eastern coast of Gyeongsang."
