In Context
In the Philippines, tropical cyclone is the umbrella term PAGASA uses before classifying a system by wind strength: tropical depression, tropical storm, severe tropical storm, typhoon, or super typhoon. The Philippine Area of Responsibility (PAR) sees an average of roughly 20 tropical cyclones a year, of which about 8 to 9 make landfall.

Extratropical Cyclone
An extratropical cyclone is a storm system that draws its energy from temperature contrasts between air masses rather than warm ocean water, unlike a tropical cyclone.
Low Pressure Area (LPA)
A low pressure area, or LPA, is a region where atmospheric pressure is lower than its surroundings, often the earliest stage PAGASA flags before a system strengthens into a tropical depression.
Post-Tropical Cyclone
A post-tropical cyclone is a former tropical cyclone that has lost its tropical characteristics, such as a warm core, but can still produce heavy rain and strong wind.
Remnant Low
A remnant low is what remains of a tropical cyclone after its organized circulation and rain bands have broken down, though the low pressure center may persist.
Severe Tropical Storm
A severe tropical storm has maximum sustained winds between 89 and 117 km/h, one step below typhoon strength.
Super Typhoon
A super typhoon is PAGASA's classification for a typhoon with maximum sustained winds exceeding 220 km/h.
Tropical Cyclone Bulletin
A tropical cyclone bulletin is PAGASA's regularly updated advisory covering a storm's position, intensity, forecast track, and wind signals in effect.
Tropical Depression
A tropical depression is a tropical cyclone with maximum sustained winds of 55 km/h or less, the first classification stage under PAGASA's wind signal system.
