Ever wondered how PAGASA names PH tropical cyclones?

The weather bureau has now released its list of tropical cyclone names for 2020!

The month of June is fast approaching which means soon enough, rainy season is going to be declared by the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA).

This means that tropical cyclones are on its way to the Philippine Area of Responsibility (PAR), and the country should expect colder weather in the coming months.

Currently, there is a tropical depression named “Ambo” near the Mindanao island. It is the first tropical cyclone for 2020—the first of around 20 cyclones (a yearly average) for the year.

Because of this, PAGASA has now released the list of names of tropical cyclones for the current year. Here are the 25 tropical cyclone names for the year, with the exception of the letter X:

  • Ambo
  • Butchoy
  • Carina
  • Dindo
  • Enteng
  • Ferdie
  • Gener
  • Helen
  • Igme
  • Julian
  • Kristine
  • Leon
  • Marce
  • Nika
  • Ofel
  • Pepito
  • Quinta
  • Rolly
  • Siony
  • Tonyo
  • Ulysses
  • Vicky
  • Warren
  • Yoyong
  • Zosimo

If in case there will be more than 25 tropical cyclones to enter the PAR, the names chosen beforehand from an auxiliary list will be used. The 2020 auxiliary names are: Alamid, Bruno, Conching, Dolor, Ernie, Florante, Gerardo, Hernan, Isko, and Jerome.

The Philippines’s weather bureau has a system for naming tropical cyclones that enter the PAR. There are four lists for both regular and auxiliary names that are used alternately to name the bagyo. For example, this year’s names will be used once again by 2024, then 2028, and so on.

However, names of particularly deadly or destructive tropical cyclones are “retired” or decommissioned. There are two conditions for a name to be decommissioned by PAGASA: the tropical cyclone should have caused at least 300 deaths and/or destroyed more than P1 billion worth of infrastructure and agriculture.

The latest names to have been retired were Tisoy and Ursula, both 2019 typhoons. Bagyong Tisoy only caused four deaths but ravaged around P6.6 billion worth of infrastructure and agriculture, while bagyong Ursula caused 57 deaths and P4.3 billion worth of damages.
