Philippines
Since 1963, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), have assigned their own names to typhoons that pass through its area of responsibility. Unlike the World Meteorological Organization's standard of assigning names to tropical cyclones when they reach wind-speeds of 65 km/h, (40 mph), PAGASA assigns a name to a tropical depression when they either form or move into their area of responsibility. Four sets of tropical cyclone names are rotated annually with typhoon names stricken from the list should they do more than 1 billion Pesos worth of damage to the Philippines and or cause 300 or more deaths. Should the list of names for a given year prove insufficient, names are taken from an auxiliary list.
