Project Severe Weather Archive of the Philippines (SWAP) digitalizes the severe weather events focused on Tornadoes, Hails, and Waterspouts along its underlying information; a key to understanding climatological baseline within the Philippine Archipelago.

Today, we are issuing the 3rd Data Release for the Severe Weather Archive of the Philippines (known as SWAP DR3) - containing more than 1000 severe weather events across the Philippines dating back 1960s.

Additionally, we will be presenting the article we published last year pertaining to the climatology of severe weather events using SWAP DR2 in the Philippine Meteorological Society's Annual Convention today (17 March 2025) at Novotel, Cubao, Quezon City - as part of the celebration of the National/World Meteorological Day.

2024 was an outlier to our severe weather climatology. +100 tornadoes and +100 waterspouts (not included in the data visualization) are reported. The increase in such numbers are due to the population density effect and more technological access (which is good since that's how any other community-driven severe weather databases start). At the moment, we're close to 500 tornadoes from 1968-Present.

Handpicked by yours, here are 5 of the most prolific philippine tornadoes/waterspouts of 2024. One of those 'handpicked' tornadoes has on-going case study.

In any order:

1. 20240925 - La Castellana, Negros Occidental tornado (merger product from Murcia, Negros Occidental storm). Multiple-vortex tornado.
2. 20241022 - Quintuplet (yes 5 vortices!) tornadoes in Lian, Batangas. 1 vortex in land, 4 waterspouts (2 cyclonic and 2 non-cyclonic). Tropical cyclone tornadoes (TY Kristine/Trami).
3. 20240527 - Arayat, Pampanga tornado. Very discrete tornadic supercell.
4. 20241117 - Aparri, Cagayan tornado. Also another tropical cyclone tornado (STY Pepito/Man-Yi).
5. 20240816 - Getafe, Bohol waterspout (Sidewinder).
