Set the alarm for 2:51 a.m.

Web alarm clock for 2:51 a.m.

Before handing over the watch, you brief the next person on which windows still need securing as the typhoon approaches. Set the alarm for 2:51 am so the changeover does not leave an unchecked room or loose latch behind. That leaves enough time for one final walk-through before 3:00 am, while responsibilities are still clear between you.

Because the signal will matter during a safety handover, test it now at a nearby time rather than assuming it will sound later. Check that the tone is audible from the farthest room, then return the setting to 2:51 am. Keep this browser page active and the phone or computer awake; otherwise, the alarm may stay silent and the windows could remain unsecured when the next person expects the reminder.

During a humid Philippine night, the person taking over may move repeatedly between an air-conditioned room and warmer areas near the windows. Place the phone where the alarm can be heard over the air conditioner, but away from curtains, open gaps, or surfaces that may get damp. At 2:51 am, keep a light outer layer nearby for the indoor chill and use the remaining minutes for a steady room-by-room check.
