What the National Weather Service wrote

A person from the public estimated ping pong size hail as she was rafting on the Salmon River about 100 yards north of the Salmon River I-93 bridge about one mile south of Carmen, Idaho. Their floating party was unable to reach the beach due to strong southerly winds and proceeded to be pelted by large hail for at least five minutes. She reported vivid black and blue bruises on her arms and legs. Her garden located in Carmen was damaged extensively by the hail.

The wider storm

A 40 to 50 knot mid-level southwest jet maximum combined with unstable conditions over Lemhi County helped initiate a large supercell thunderstorm that brought wind and hail. As the main upper low over Washington and Oregon pushed eastward, thunderstorms developed over Idaho County. One of these storms brought heavy rain that triggered flash flooding over the Sheep Fire Burn area.

Began near Carmen (45.2310, -113.8950).
