No, because they can be seen everywhere and they can be found near the land or in the Philippine Atmospheric, Geophysical and Astronomical Services Administration's radar.
Tropical cyclones can only form over oceans of the world except in the South Atlantic Ocean and the south eastern Pacific where a tropical cyclone could never be formed due to the cooler sea surface temperature and higher vertical wind shears. They develop at latitudes usually greater than 5° from the equator.
