Web alarm clock for 5:24 p.m.
You have just woken up at 5:24 pm, with the mangrove seedlings still waiting for their first inspection after the storm. Set the alarm before you get out of bed, then use the time before 6:00 pm to gather boots, gloves, and a torch and check whether the route is passable. That leaves the actual visit as the next clear task rather than something to remember while you are still shaking off sleep.
Your mangrove inspection may begin near people talking, electric fans running, traffic passing, or waves breaking along the shore, so test whether the alarm can be heard above that background noise. Raise your phone's media volume and choose a distinct signal, then keep it close enough to notice. The alarm will not sound if this page is closed or your phone goes to sleep, which could delay the mangrove seedling check; keep the page open and the phone awake until it rings.
Because the seedling visit falls late in the Philippine afternoon, have some water before leaving, especially if the air remains warm and humid after the storm. A light merienda such as fruit or bread is practical if you have not eaten since waking. Leave a heavy meal until after the mangrove check, so preparation does not use the remaining daylight or make the trip feel rushed.
