Site set the timer to 144 seconds

Web timer for 144 seconds

You start the 144 seconds again, moving from one window to the next because the first pass showed which shutters still rattle. While the timer runs, tighten each latch, pull loose panels firmly into place, and check that nothing can swing outward when a sudden Philippine squall drives rain across the house.

You may slip your phone into a pocket while both hands hold a shutter, leaving the timer tab behind another screen. The countdown usually keeps running there, but the alert may be muted by phone settings or delayed by battery restrictions. When you uncover the tab, use the remaining display as your guide rather than restarting unless the first alert has already passed.

You work more steadily on the second round if you handle sun-heated metal with a cloth and test the shaded shutters first. Afternoon heat can make frames expand and latches resist, so use this short interval to secure what closes cleanly, then return to any stubborn fitting without forcing it. That keeps the brief check focused as dark clouds build.
