Set the alarm for 11:25 a.m.

Web alarm clock for 11:25 a.m.

As you hand the clearing job to the next person at 11:25 am, set the alarm for the point when the storm-drain grate should be checked again. That leaves a clear marker before 12:00 pm, whether the forecast rain is already darkening the sky or the gutter still looks dry. Mention any leaves, plastic, or silt you have removed so the handover covers what remains.

While the other person works near the drain, keep the alarm where its sound will reach whoever needs to respond. A phone may quietly send the alert to connected earphones, even when nobody is wearing them, so check the audio output and choose a noticeable volume. The alarm cannot protect the drain if you close the browser page or let the phone sleep; in that case, the clearing reminder may never sound. Keep the page open and the phone awake until the alert appears.

By late morning, traffic, tricycles, nearby construction, and gathering rain can make the roadside louder than it was earlier. Place the phone away from running water but close enough for its alarm to stand out from that changing noise. At 11:25 am, a vibration setting can add a visible or physical cue during the handover, especially if a sudden downpour begins before noon.
