forecast direction and speed of movement of the tropical cyclone (relative to the Philippine landmass) at the time of TCB issuance. As a tropical cyclone approaches or moves over land, intensifies or becomes wider, a wind signal raised over a particular locality can be escalated to a higher wind signal level; multiple wind signals hoisted over various areas can also be escalated, and the extent or area where there are active wind signals can also be expanded. On the other hand, wind signals are de-escalated to lower wind signal levels, or else lifted or deactivated, and the area where wind signals are active becomes smaller when the tropical cyclone moves away from land, weakens or scales down in its width. The TCWS system also allows for the skipping of wind signal levels, especially when there is a rapid change in the state of the tropical cyclone.
721:, which is the period of time within which a locality should expect the arrival of a range of tropical cyclone wind intensity, i.e. the number of hours from the first time a wind signal is hoisted until the expected range of tropical cyclone wind intensity starts impacting a particular locality. This makes the TCWS an early warning system, wherein the initial issuance of a particular signal level over a locality does not mean that the inclement weather conditions indicated for the given signal level is already prevailing. The lead time is used to raise awareness of the approximate remaining length of time for the public to prepare against impending tropical cyclone winds. Lead times in the TCWS system are valid only for the first issuance of a particular wind signal; higher wind signal levels correspond to higher wind speeds and shorter lead times. 702: 1334: 1349:) that they have amended both the tropical cyclone intensity scale and the Tropical Cyclone Wind Signals (TCWS) as a result of a "sunset review" of the agency's tropical cyclone warning system. In a press release, PAGASA stated that the intensity scale and TCWS revisions are based on the "adoption of best practices from other TC warning centers and regionally-accepted operational standards, developments in objective guidance for TC wind swaths, operational experiences and challenges encountered by typhoon forecasters, and feedback from end-users and stakeholders." 1080: 1437:, which empirically assigns a number from 0 to 12 to measure wind speed. As a result, the wind intensity ranges in the modified TCWS parallels that of the revised tropical cyclone intensity scale, i.e. each signal level in the modified TCWS is associated with each tropical cyclone category (TCWS #1 corresponding to tropical depression, TCWS #2 for tropical storm, and so on). This March 2022 update of the tropical cyclone intensity scale and TCWS is the version that is currently being implemented in the Philippines. 1095: 653:, which is collectively placed under a single wind signal level. All TCWS signal levels in effect in various localities affected or to be affected by tropical cyclone winds are enumerated in each TCB issuance, including the escalation, de-escalation or lifting of such signal levels.

tropical cyclone wind strength, thus informing the public as early as possible of the approximate remaining length of time for preparations against impending tropical cyclone winds. Lead times remain in use in succeeding versions of PAGASA's tropical cyclone signal systems, with higher signal levels corresponding to both stronger wind speeds and shorter lead times.

In this amendment, PAGASA introduced the "severe tropical storm" category (in between the tropical storm and typhoon categories) and the "super typhoon" category, the latter being defined as an extreme tropical cyclone with 10-minute maximum sustained winds

For example, winds of 39–61 km/h is expected to occur within the next 36 hours when a specific locality is initially put under TCWS #1 due to an approaching tropical cyclone; thus, that locality has at least 36 hours to prepare before such winds arrive or start to occur. When the wind signal in the

For the intensity scale, PAGASA lowered the threshold wind speed for classifying super typhoons from 220 km/h to 185 km/h and defined a super typhoon as an extreme tropical cyclone with 10-minute maximum sustained winds reaching 185 km/h or greater (the range of wind speed for typhoon category is

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
