Typhoon Dan, known in the Philippines as Typhoon Saling, was the third of a series of

millibars. The storm moved ashore in central Vietnam and dissipated after moving inland. The storm caused extensive damage throughout its course. In the Philippines, Dan left hundreds of thousands homeless and killed 58 people. Power outages were extensive in the Manila
region. In Vietnam, the storm's high winds and heavy rains caused extensive damage and loss of life. More than 500,000 structures were damaged or destroyed and at least 43 people were killed across the country.

triangle Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

On October 6, 1989, a tropical disturbance formed in the monsoon trough near the island of Chuuk. An advisory by the Joint Typhoon Warning Center (JTWC) assessed the system as having a "poor" chance to develop due to strong wind shear in the region.[nb 1] A day later, the potential of development was adjusted to "fair". On October 8, the wind shear relented and a well-defined band persisted near the storm's center of circulation. As a result, a Tropical Cyclone Formation Alert was issued.[2] That same day, the Japan Meteorological Agency (JMA) classified the storm as a tropical depression.[3][nb 2] At 1200 UTC, the JTWC issued their first warning on Tropical Depression 29W. At the time, it was centered about 70 mi (110 km) northeast of Yap.[2]

About 18 hours later, the depression was upgraded to a tropical storm and given the name Dan. The cyclone moved westward at 17 to 23 mph (27 to 37 km/h), and convection continued to mature.

Philippine Atmospheric, Geophysical and Astronomical Services Administration also monitored the storm, assigning it with the local name Saling.[5] The JMA upgraded it to a tropical storm on October 9; both agencies recognized it as a typhoon the next day after an eye became visible and outflow improved in the northwestern quadrant.[2][3] Dan made landfall on the southeastern coast of Luzon in the Philippines, and its center tracked just south of Ninoy Aquino International Airport.[2]

Dan crossed over the island and emerged into the

millibars.[3]

The storm passed about 70 mi (110 km) south of

Hainan Island and weakened somewhat. Increased wind shear further deteriorated the system as it approached the coast of Vietnam. The storm moved inland at around 1200 UTC on October 13,[2] at which point the JMA downgraded it to a severe tropical storm and the JTWC issued their final advisory on the disturbance.[2][3] The circulation ultimately dissipated over the mountainous terrain and its remnants continued to move westward into Laos.[2]

Impact

Although it was relatively weak, the storm caused severe damage. In the Philippines, 58 fatalities from the cyclone were reported, with an additional 121 injuries. In total, 682,699 people, or 135,245 families, were affected by the typhoon, and 49,972 houses sustained damage.

state of calamity" there and in surrounding areas.[9] In the wake of the storm, the nation's military provided $300,000 worth of food for residents in evacuation centers.[6] The Department of Social Welfare and Development also provided $371,000 worth of emergency relief assistance to 2,700 families displaced by the storm.[11] Despite the scale of damage from Dan and other typhoons in the region, no request for international assistance was made by the Philippine Government.[6] As the storm progressed westward, it buffeted Hainan Island with gale-force winds and exacerbated damage caused by Typhoons Angela and Brian.[9] Collectively, the three storms were responsible for 63 fatalities on the island, most of which were attributed to Brian.[12]

Damage in Vietnam was also extensive.
