Web alarm clock for 2:40 p.m.
As you finish checking the latest PAGASA heat bulletin and head away, set the alarm for 2:40 pm so the advisory does not slip behind the rest of your afternoon. The alert leaves a clear point before 3:00 pm to act on any guidance that affects plans at home.
Your PAGASA check may send you into messages or another app, leaving the alarm page in the background. Keep the browser running and allow its notifications and sound; switching away usually does not cancel the alert, although phone settings may silence it. Do not depend on this alarm for the PAGASA bulletin if you close the page completely or let the phone go to sleep, because the alert may never sound.
If your 2:40 pm reminder changes what happens in the house, tell everyone before you step away—especially anyone using the kitchen, working near a sunny window, or planning to go outside. A short note about what the PAGASA update means for shared errands or afternoon chores can prevent confusion when the alarm sounds. Place the phone where the tone will be heard without startling someone who is resting.
