Set the alarm for 2:50 p.m.

Web alarm clock for 2:50 p.m.

Before handing the river crossing to the next person, set the alarm for 2:50 pm and pass along the latest water conditions, the chosen route, and the point for turning back. That leaves a clear checkpoint before 3:00 pm, when rising water may change what is safe or practical. The handover should include who is crossing, who is watching the bank, and what signal means stop.

During the handover, check whether your phone is in silent mode and confirm that this browser alarm can still be heard at the volume you expect. A visible countdown alone may not alert the person taking over. Keep this page active and the phone awake: if either is closed down, the alarm may not sound, leaving the river crossing without its planned 2:50 pm warning.

Once responsibility has changed hands at midday, protect the sleep you expect to get afterward by settling any remaining questions before you step away. Write the agreed route and stopping point in one short note, then leave the next person to follow it without waking you for details. Keep a separate backup alarm only if you must be available again later, so this checkpoint does not quietly turn into an open-ended watch.
