Tropical Storm Ewiniar (2018)

Ewiniar combined with the southwest monsoon to produce thunderstorms and gusty winds over Vietnam.[14] Farmers were urged to complete the rice harvest before the onset of heavy rain.[15] Tourists were evacuated from the Chàm Islands,[16] while about 2,000 tourists were stranded on Lý Sơn Island.[17] Several roads in Ho Chi Minh City were inundated with water up to 30 cm (12 in) deep.[18] Landslides damaged three houses in Lào Cai Province and two more in Thanh Hóa Province, while floods washed away two houses in Cao Bằng Province. A person was killed in Quan Sơn District.[19]

Ewiniar brought heavy rain to South China and Jiangnan for seven days, affecting 211,200 people with floods and landslides. Rainfall totals exceeded 250 mm (9.8 in) over 66,000 km² (25,000 sq mi) of land. A peak rainfall accumulation of 845 mm (33.3 in) was observed at Luotang Reservoir in Guangdong. Eight cities saw new records for highest daily rainfall in June.[10][20] In Hainan, schools were closed in the capital Haikou.[21] About 5,530 people (mostly fishermen) were moved to safety. High-speed rail services around the island were suspended and the Yuehai Ferry halted operations, while dozens of flights were cancelled at Haikou Meilan International Airport and Sanya Phoenix International Airport.[22] The Qiongzhou Strait was closed to passenger ships on June 4 and 5.[21] In Guangdong, 73,000 residents were evacuated to over 3,000 emergency shelters. At Guangzhou Baiyun International Airport, 73 outbound flights and 71 inbound flights were cancelled.[23] A total of 404 ships took shelter in the Port of Zhanjiang.[24]

The passage of Ewiniar resulted in 13 fatalities and ¥5.19 billion (US$749 million) of damage.[20] Landslides killed five people in Xinxing County[25] and caused another person in Jiangmen to go missing. Twenty-nine houses collapsed and 27,350 hectares (67,600 acres) of crops were damaged.[10] In Foshan, two women died after being electrocuted by faulty electrical wiring on a digital billboard at a bus stop.[26] Ewiniar also spawned a tornado in Dali,[27] which blew off a market's 400 m² (4,300 sq ft) roof and damaged three cars but caused no casualties. A construction site in Nansha District collapsed under strong winds, killing one and injuring eight others.[28] Heavy rain caused the exterior of a building in Longgang District, Shenzhen to collapse, resulting in four deaths and four injuries.[29] Roads were blocked by floods in Haikou, disrupting traffic.[22] Floods occurred during the National College Entrance Examinations on June 7–8, obstructing students' travel. Police and firefighters were dispatched to examination centers to ensure students could arrive safely and on time.[26][23] In Zhaoqing, 200 students were ferried to their examination centers using trucks, dinghies, and steamboats.[30] Insured losses in Guangdong (excluding the city of Shenzhen) were approximately ¥300 million (US$47 million).[31] Authorities allocated ¥290,000 (US$45,000) of funds for disaster relief and distributed bottled water, food, tents, beds, and towels to displaced residents.[22]

Ewiniar was the first tropical cyclone to affect Hong Kong in 2018. The system brought flooding rain and squalls to Hong Kong from June 5–8. Rainfall totals across the region mostly exceeded 250 mm (9.8 in); northeast parts of the New Territories recorded over 400 mm (16 in) of rain. The No. 3 Strong Wind Signal was raised over the territory from June 7–8,[32] during which kindergartens and schools for children with disabilities were closed and bunker operations at the Port of Hong Kong were suspended.[33][34] Fallen trees damaged vehicles and obstructed traffic, with one such incident in Sai Wan Ho resulting in an injury.[32] Flooding occurred in several areas in the city, with reported incidents in Kam Shan, Diamond Hill, and Man Kam To.[35] A waterspout was sighted near Cheung Chau on June 7.[36] A storm surge of 0.68 m (2.2 ft) was measured at Tsim Bei Tsui.[32] In neighboring Macao, the No. 3 Strong Wind Signal was also issued from June 7–8.
