Tropical Storm Sinlaku was a weak tropical cyclone that impacted Vietnam, Thailand and Laos in August 2020. Beginning as a tropical depression on July 31 in the South China Sea, Sinlaku was the fifth storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow west-northwest course, strengthening into a tropical storm the following day despite its monsoonal structure. The storm subsequently made landfall in Vietnam as a broad but weak tropical storm. Persistent land interaction weakened Sinlaku, leading to its dissipation on August 3.
Sinlaku brought heavy monsoonal rains to much of Southeast Asia, especially to Vietnam, Laos, and Thailand. Two people were killed in Vietnam, and two people were killed in Thailand.
