Since 1963, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has assigned local names to a tropical cyclone should it move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N, even if the cyclone has had an international name assigned to it.
[6] The practice of retiring significant names was started during 1955 by the United States Weather Bureau in the Atlantic Ocean, after hurricanes Carol, Edna, and Hazel struck the Northeastern United States and caused a significant amount of damage in the previous year.
[4][7] [8][9] PAGASA retires a name it has assigned after the season if the system has either killed at least 300 people or caused at least PHP1 billion in damage to infrastructure and agriculture, based on reports from the National Disaster Risk Reduction and Management Council.
[10] Several names have also been removed for reasons other than causing a significant amount of death/destruction, such as Gloria in 2005, (due to then-president Gloria Macapagal Arroyo's disputed win in the 2004 Philippine presidential election and her subsequent involvement in the Hello Garci scandal) and Nonoy in 2015 (due to similarities to the term "Noynoy", then-president Benigno Aquino III's nickname).
[11][12] As of 2024[update], 77 tropical cyclone names have been retired, with the most recent being Egay and Goring of the 2023 season.
