A super typhoon packs maximum sustained winds of at least 185 kilometers per hour, based on PAGASA’s revised definition. Previously, PAGASA defined a super typhoon as a tropical cyclone with more than 220 kph maximum sustained winds. The new definition is similar to the USA Joint Typhoon Warning Center&#x27;s super typhoon classification, when converted to 10-minute averaging. PAGASA introduced this category in 2015 to better reflect the potential dangers of super typhoons like Yolanda, the strongest storm to ever hit land, which left more than 7,360 people dead or missing across central Philippines in 2013. The state weather bureau also amended its tropical cyclone wind signals, which now correspond to the following categories. Tropical Depression Less than 62 kilometers per hour maximum sustained winds Highest wind signal: 1 Tropical Storm 62-88 kph maximum sustained winds Highest wind signal: 2Severe Tropical Storm 89-117 kph maximum sustained winds Highest wind signal: 3 Typhoon 118-184 kph maximum sustained winds Highest wind signal: 4 Super Typhoon 185 kph or higher maximum sustained winds Highest wind signal: 5 PAGASA also decommissioned the names of 3 destructive storms in 2021, including <a href="https://news.abs-cbn.com/news/09/27/21/samar-nasa-state-of-calamity-dahil-sa-bagyong-jolina">Jolina</a>, <a href="https://news.abs-cbn.com/news/01/21/22/un-typhoon-odette-destruction-badly-underestimated">Maring</a>, and <a href="https://news.abs-cbn.com/news/10/17/21/maring-death-toll-climbs-to-23-ndrrmc">Odette</a>. From 2025, they will be replaced with the names Jacinto, Mirasol, and Opong, respectively.<blockquote class="twitter-tweet">LOOK: <a href="https://twitter.com/dost_pagasa?ref_src=twsrc%5Etfw">@dost_pagasa</a> announces the decommissioning of tropical cyclone names Jolina, Maring, &amp; Odette during its Scientific Forum this morning.

Forty-seven typhoon names have been decommissioned since the naming scheme was introduced in 2001.
