Preparations, impact, and aftermath
editPhilippines
editBeginning on August 23, 104 municipalities temporarily suspended classes, with government work in Ilocos Norte and parts of Ilocos Sur also being suspended.[2] Residents of areas in and surrounding Metro Manila were cautioned about monsoon-related floods and landslides,[3] with rough seas around northern and central Luzon prompting the issuance of a gale warning and advisories against small vessels setting sail.[4]
Luis enhanced the Philippine southwest monsoon, causing rain in parts of Luzon.[1] A total of 304,900 people were affected in the Ilocos Region and the Cordillera Administrative Region. 488 houses were damaged in both regions, of which 58 were totally damaged.[5] 211 areas experienced flooding; the highest of which occurred at Cabatuan Bridge in Alaminos, Pangasinan, where waters reached 20 feet (6.1 m) above normal. 28 landslides were reported; one bridge and 95 sections of road experienced disruptions due to landslides, flooding, debris, or other causes. 23 areas, many in Baguio, experienced temporary power interruptions during Luis' passage.[2] Baguio recorded the highest amount of rainfall in 24 hours, receiving 216 millimetres (8.5 in) of rain. Laoag recorded a total of 406 millimetres (16.0 in) of rain during the storm's duration, the highest in the country.[1] The Marusay River reached a water level exceeding 2.4 metres (7.9 ft), surpassing the critical level of 2.2 metres (7.2 ft). The San Roque Dam began releasing water due to increasing water levels in its reservoir.[6]
₱12.8 million (US$243 thousand) in assistance was provided by several organizations to affected areas, with ₱7 million (US$132 thousand) alone being provided by the Department of Social Welfare and Development.[5]

Parts of Kaohsiung and Pingtung County were issued extremely heavy rain warnings,[7] with the rest of mainland Taiwan receiving heavy rain warnings. Six thousand people were evacuated, with roads and rails being closed due to the tropical depression.[8]
Seven people were killed in Taiwan, with over 140 people being injured. Total damages amounted to at least NT$992 million (US$34 million) across agriculture and education.[9] The reservoir of Zengwen Dam overflowed, prompting the release of the stored water.[8] Five tankers with over 60 crewmembers ran aground near Kaohsiung.[10]
