Web alarm clock for 10:42 a.m.
While you watch the clock for 10:42 am, keep your gloves and a small scoop ready so you can clear the storm-drain grate at the planned moment before the forecast downpour. Setting the alarm lets you wait indoors without repeatedly checking the time. Once the grate is clear, the remaining morning still leads naturally into 11:00 am.
Because this job depends on a timely warning, set the alarm on a phone or computer that will remain awake until it sounds. A screen that sleeps too soon may prevent the storm-drain reminder from reaching you, and the downpour could arrive while leaves still block the grate. Keep the device powered, leave this page open, and set its volume where you can hear it from the room in which you are waiting.
Before stepping outside during the late morning, tell other people in the house that the 10:42 am alarm marks your trip to the storm drain. A clear explanation keeps someone from silencing the sound or wondering why you are heading out with gloves just before rain. Place the device away from anyone resting, but close enough that you can hear the signal promptly.
