Online timer for 170 seconds
On the second run, keep the 170 seconds going while you return the household rain gauge to its usual spot and check that the opening is clear. You may already have written down the first reading, so this repeat gives you time to confirm the measurement, note when the shower passed, and avoid mistaking leftover drops on the funnel for fresh rainfall.
Recording a rain-gauge reading can take longer when the scale is wet, the markings are faint, or another squall arrives. The interval can be changed directly on the page to match what remains: shorten it if the number and time are already noted, or extend it if you still need to empty the gauge carefully and settle it upright in the garden.
While you finish the second check, consider anyone working, resting, or studying nearby before leaving the signal audible. A phone placed on a veranda table may be heard through an open door, especially during a quiet patch between showers. Keeping it close, lowering its volume, or using vibration lets you notice the end without making the alert part of everyone else’s afternoon.
Common questions
What might make this interval too short for recording a household rain-gauge reading?
Wind-driven rain can leave droplets around the funnel, and a closely marked scale may need a slower look. Add a little time if you must steady, empty, and replace the gauge after noting the measurement.
What if I finish the second rain-gauge reading before the countdown ends?
Stop it once the reading, time, and recent weather are written down. This also prevents an unnecessary signal from disturbing people nearby.
