A woman is still missing this afternoon after being swept away by the Wailuku River in Hilo last night during a flash flooding event.

Firefighters said they were still searching for the woman, in her mid-20s, this afternoon.

On Friday, the woman was hiking with a man above Piihonua Falls when they were both swept away by quickly rising floodwaters, firefighters said.

The man made it to the riverbank, but lost contact with the woman.

Firefighters responded at about 6:15 p.m., but could not search in the “extremely high” water and instead searched along the riverbank from Piihonua Bridge to Boiling Pots.

Firefighters said the search was called off due to darkness at 7:25 p.m. and they planned to resume the search at first light.
