Typhoon Dot, known in the Philippines as Typhoon Kuring, was one of several

Hainan Island. A weakened storm then entered the Gulf of Tonkin
before striking northern Vietnam and dissipating on June 12.

Throughout its course, Typhoon Dot produced heavy rains in the Philippines, China and Vietnam, resulting in significant damage and eight fatalities. The most severe impacts took place on Hainan Island where 1,400 homes were destroyed and another 60,000 were damaged. In Vietnam, Dot exacerbated flooding triggered in late May by

Tropical Storm Cecil

In early June 1989, the

Philippine Atmospheric, Geophysical and Astronomical Services Administration also monitored the storm, assigning it with the local name Kuring.[5] Tracking generally towards the west-northwest, the depression intensified into a Tropical Storm and was given the name Dot, 12 hours before making landfall in Samar on June 6.[2]

Gradual weakening occurred as Dot neared Hainan Island on June 9. The typhoon subsequently made landfall near

Hai Phong, Vietnam. Once onshore, Dot quickly degraded over the mountainous terrain of northern Vietnam, and was last noted on June 12.[2][3]

Impact

Typhoon Dot over Hainan Island on June 10

Tropical Storm Dot produced widespread rainfall in the Philippines, leading to several landslides. In Toledo City, the Carmen

Concentrator had to temporarily shut down after a landslide disrupted the facility's water supply. As a result, the Atlas Consolidated Mining and Development Corporation lost approximately 272,000 kg (600,000 lb) of copper.[5]

Across Hainan Island, the storm produced heavy rains and damaging winds that left eight cities without power or telephone service.

Guangxi Province, heavy rains caused additional flooding that destroyed 300 homes and injured eight people. However, these rains also helped alleviate drought conditions in the region.[7] At Tai Mo Shan in Hong Kong, sustained winds from Dot reached 79 km/h (49 mph) and gusts peaked at 110 km/h (70 mph). More than 55,000 hectares (140,000 acres) of crops were flooded, the majority of which were rice fields.[7]

Roughly two weeks after

Tropical Storm Cecil devastated parts of Vietnam,[8] Dot caused further flooding along the Red River Delta. Portions of Hanoi were inundated with up to 1 m (3 ft). Winds up to 116 km/h (72 mph) reportedly affected coastal areas near where the typhoon moved ashore.[9] Nearly 162,000 hectares (400,000 acres) of rice fields were submerged by the storm. At least six fatalities were attributed to the storm in Vietnam, and many more were injured.[10]
