'Layer upon layer of miracles': How Nepal flood survivors were rescued from tunnel

From searching for a buried tunnel entrance to blowing up rocks the size of cars, rescuers had to surmount multiple challenges to reach survivors.

Flooding can cut off roads with little warning, damage homes near low-lying areas, and disrupt power and water service. Even a few inches of moving water can carry away a vehicle.

This report is based on information from BBC World, monitored by Alert USA's verified emergency feed.

Alert USA anticipates a high chance of travel disruptions, elevated property risk in low-lying areas, and possible power outages while the event is active.

Recommended steps: avoid flooded roads — turn around, don't drown; move to higher ground if you are in a low-lying area; charge phones and prepare for power loss; check on family and neighbors.

Alert USA is tracking this flood event and will update this report as verified information becomes available.
