    If a Public Storm Warning Signal Number is raised or put in operation for the first time, meteorological conditions affixed to the signal aren’t yet in place in the region. The reason behind this is the reason that the message is designed to signal that the incident is likely in the conditions set out. It is vital to be aware that the lead time estimate to determine the wind range for each number is only applicable at the point that the number is in force in the very first instance. Thus the weather forecast is expected to last for a minimum of 36 hours after PSWS #1 is established in the initial position; at the very minimum 24 hours in the case of PSWS #2 and at least 18 hours for PSWS #3; at least 18 hours PSWS #3 and at minimum twelve hours to PSWS #4 and 12 hours to PSWS 5. The time to lead decreases when the next issue of PSWS’s warning bulletin , as the signal number has been put in position as the tropical cyclone is moving closer.

    HTML0It is also important to remember that tropical cyclones are constantly moving, usually towards or toward to the Philippines in the event that PAGASA releases the advisory. Thus PSWS #1 is the PSWS #1, the Public Storm Warning Signal Number for the location that is at risk or in danger can be modified or decreased. That means PSWS #1(Public Storm Warning Signal # 1) could change into PSWS #2, later to PSWS #3 and then to PSWS #4 when an severe Typhoon approaches or when the typhoon is moving away.
