On September 15, a tropical depression formed from a broad area of convection near Guam. At 12:00 UTC, the JMA upgraded it into a tropical storm, naming it Pulasan, a replacement name for Rumbia. A few hours later, the JTWC issued a TCFA for the system.[1] The next day, the JTWC classified it as a tropical storm. However, it maintained typical characteristics of a monsoon depression. Pulasan entered the Philippine Area of Responsibility late on September 17 and was designated as Tropical Storm Helen by PAGASA.[2] Pulasan continued to drift northwestwards until it passed through the Ryukyu Islands and made landfall over Zhoushan, China as a weakening tropical storm.[3] The terrain interaction with Pulasan made its convection disorganized, causing it to weaken into a tropical depression.[4] It later turned east-northeast as it headed for South Korea, and re-strengthened to a tropical storm in the Sea of Japan.[5]

Preparations

[edit]

South Korea

[edit]

At least 903 people from 581 households were evacuated across six provinces in South Korea.[6]

Japan

[edit]

As Pulasan approached Japan, 44,700 residents from Wajima, Suzu, and Noto in Ishikawa Prefecture were given evacuation orders, along with 16,000 others in Yamagata and Niigata Prefectures.[7] The Japan Meteorological Agency issued the highest level of alert for heavy rain across several cities in the Ishikawa.[8]

Philippines

[edit]

Pulasan strengthened the southwest monsoon affecting the Philippines. The storm, along with Soulik and Typhoon Bebinca, was blamed for a total of 24 deaths, 13 injuries and 12 missing across the country.[9]

China

[edit]

Due to Pulasan, winds of 83 km/h (52 mph) were recorded in Fengxian, Shanghai, where several roads and neighborhoods were flooded.[10]

South Korea

[edit]

The cities of Changwon, Yeosu and Busan recorded 519.2 mm (20.44 in), 399.5 mm (15.73 in) and 390.2 mm (15.36 in) of rainfall respectively on September 21. Flooding affected 83 sections of public roads, leading to 18 incidents of soil loss and a wall collapse, 30 private facilities and 27 houses. Two trucks fell into a sinkhole in Busan.[6]

Japan

[edit]

Heavy rains caused by Pulasan triggered widespread landslides and flooding in the Noto Peninsula, causing extensive damage which was excarcabated by the 2024 Noto earthquake which devastated the region in January.[8] In Wajima, 120 mm (4.7 in) of rainfall was recorded within an hour.[11] Up to 10 people were left missing in the town, including four due to a landslide at a construction site.[11] In Suzu, one person drowned and another was missing. In Noto, one person was missing and two others were critically injured after a landslide struck their home. At least 12 rivers across Ishikawa overflowed, and 6,500 households were left without power in the prefecture, according to Hokuriku Electric Power Company.[8]
