The TCWS system is a tiered system (from TCWS #1 to #5) that allows for the escalation, de-escalation or lifting of wind signals in every TCB issuance depending on the tropical cyclone wind intensity, the extent of tropical cyclone winds (i.e. radius of tropical cyclone wind circulation) and the forecast direction and speed of movement of the ...
TCWS #1 winds of 39–61 km/h (21–33 kn; 24–38 mph) are prevailing or expected to occur within 36 hours: TCWS #2 winds of 62–88 km/h (33–48 kn; 39–55 mph) are prevailing or expected to occur within 24 hours

For systems below tropical cyclone strength there are various terms used, including Tropical Disturbance, Tropical Low and Tropical Depression. [28] A tropical disturbance is defined as being a non-frontal system of synoptic scale originating over the tropics, with persistent enhanced convection or some indication of a circulation. [28]
The Philippines is a Typhoon (Tropical Cyclone)-prone country, with approximately 20 Tropical Cyclones entering its area of responsibility per year. Locally known generally as bagyo (), [3] typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity.
Typhoon Toraji, known in the Philippines as Typhoon Nika, was a fairly strong tropical cyclone that impacted the Philippines in early November 2024. It was the fourth tropical cyclone in a series to impact the Philippines, following Tropical Storm Trami and Typhoons Kong-rey, Yinxing, Usagi, and Man-yi which had occurred just a few days earlier.
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
