=== Pre-Haiyan Philippine tropical cyclone warning systems (1950s–20151879–2015) ===

The earliest issuance of a [[tropical cyclone]] [[Tropical cyclone warnings and watches|warning]] in the [[Philippines]] happened in July 7, 1879 during the [[History of the Philippines (1565–1898)|Spanish colonization era]], when Federico Faura of the ''Observatorio Meteorológico del [[Ateneo de Manila University|Ateneo Municipal de Manila]]'' (now known as the [[Manila Observatory]]) warned of a typhoon moving across Northern Luzon based on [[Barometer|barometric readings]].<ref name="PSWSHistory1"/> The primitive methods of meteorological observation and the lack of telegraph communications made it hard for the ''Observatorio'', a [[Jesuits|Jesuit]] scientific institution established in 1865, to promptly warn areas outside [[Manila (province)|Manila]]. In 1884, the institution was formalized by [[Spanish Empire|royal]] decree as the ''Observatorio Meteorológico de Manila'', leading to major improvements in their tropical cyclone monitoring and warning. In 1901, during the [[History of the Philippines (1898–1946)|American colonization period]], the ''Observatorio'' was reorganized as the ''Philippine Weather Bureau'' and was the predecessor to the now independent Philippine's state weather bureau [[PAGASA]].<ref name="PSWSHistory1"/>
