Web alarm clock for 2:29 a.m.
While you watch the clock for the right moment to close the windows before the typhoon arrives, set the alarm for 2:29 am so the task does not slip amid weather updates. That still leaves a useful stretch before 3:00 am for checking each room, bringing loose items inside, and making sure the latches are secure.
Your window check may come with rain striking the roof, gusts outside, or a television carrying advisories, so choose a signal you can clearly hear over that background noise. Raise the volume before relying on it and play a quick test while standing in the room farthest from your phone. Keep this page open and your phone awake: if either is shut down for the night, the alarm may not sound and the windows could remain unsecured.
Moving between rooms at 2:29 am can still feel warm and sticky in the Philippines, especially with windows being closed ahead of severe weather. Set the air conditioner to a comfortable level before starting, but keep its fan low enough that it does not mask the alarm. Place your phone away from the airflow and where the signal will remain audible as you secure the last window.
