Heavy rain in southern Taiwan turned a stream into a deadly hazard, killing off hopes for a quick rescue and leaving one man missing.

• A couple in their 70s riding a scooter in Wandan township were knocked down by fast-moving water that had spilled over a stream bank.
• The woman survived by grabbing onto a tree; her husband was swept downstream and is still missing.
• The water is moving too fast for rescue boats, so crews are searching the banks with drones instead.
• The coast guard has joined the search at the mouth of the Donggang River, where the current may have carried him.
• Days of nonstop rain have flooded roads across Pingtung County, catching drivers off guard.

Outlook: Searchers will keep working downstream, but the odds of a rescue fall the longer the water stays high.
