The first few months of 2020 were extremely quiet, with no tropical systems developing between the months of January and April. On May 10, the season saw its first tropical system with the development of Ambo, making it the sixth-latest starting season on record, as well as the latest since 2016. Two days later, the system strengthened to the first officially named tropical storm of the season, Vongfong. Vongfong then hit the Philippines at peak intensity, and weakened soon after landfall.
