Comparison of typhoon signals and hurricane categories
Philippine Typhoon Signals and the American Hurricane Categories are worlds apart. In this post, I'll clarify the difference between these two scale systems.

In our time when information and news from all over the world is readily available to everyone, a clash of cultures and practices is unavoidable. This usually leads to misinformation. Storm strength and warning levels is one of those always misunderstood by many people.
Here in the Philippines, we have what we call the Public Storm Warning Signal which is only up to Signal No. 4. In the US, they use the Saffir-Simpson Hurricane Category Scale which reaches up to Category 5. These two are totally different, and for this post, I will try to clear the difference between the two to avoid another misunderstanding.
But before that, I want to request to news networks like CNN to at least take extra effort in giving storm scales based on a particular region or country’s system. For example, Typhoon Parma is obviously within the Philippine Area of Responsibility and as such, they can call the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (or PAGASA) and ask for the local storm scaling system.
For my fellow Filipinos, here is a table of the difference between PAGASA’s Public Storm Warning Signal (PSWS) system and the Saffir-Simpson Hurricane Category Scale.
As you can see above, the Saffir-Simpson scale Categories 1 through 5 is equivalent to PAGASA’s Signal No.2 and No.5. Interestingly, Signal No.5 is simply “any wind speed greater than 220 km/h” which is a strong Category 4 or 5 storm. This means that a strong Category 4 and Category 5 storms are that STRONG!
Another thing to remember here is that, a super typhoon is a typhoon that reached maximum wind speed of 200 km/h according to PAGASA or 150 mph or 240 km/h according to UCAR and JTWC. This is equivalent to a strong Category 4 or Category 5 Hurricane on the Saffir-Simpson scale.
All clear? Good!
We’re done! But if you want to continue reading and know additional information (more like a trivia) then continue reading.
