If any Public Storm Warning Signal Number is erected or put into operation for the first time meteorological conditions that correspond to it aren’t yet in effect over the area.¬†This is due to the fact that the goal for the warning signal is alert that the event is imminent for the meteorological conditions that are specified.¬†It is important to note that the estimated lead time to estimate the range of winds with each specific signal is only valid after the date the particular signal is put into force for the first time.¬†Therefore, the meteorological conditions can be predicted to last at least 36 hours after PSWS #1 is in initial effect; minimum 24 hours with PSWS #2; minimum 18 hours with PSWS #3, minimum 12 hours with PSWS #4, and at least 12 hours in PSWS #5.¬†

The lead time decreases with the subsequent editions of the bulletin, as long as the signal number is in place as the tropical cyclone moves closer.It is also essential to keep in mind that tropical cyclones can be found moving; usually toward to the Philippines when PAGASA issues the warning. So it is possible that it is possible that the Public Storm Warning Signal Number for a affected or threatened location could be upgraded or reduced. 

That means PSWS #1 could updated up to PSWS #2, then to PSWS #3 and finally, to PSWS #4 when the intensity of a storm is approaching, or downgraded as the typhoon moves away.
