Event narrative

During the evening, two swimmers at Grantsville Reservoir were pushed away from the shore as a result of high winds (from outflow associated with convection moving into the area). At approximately 8:30 pm MST a 9-1-1 call was placed stating that a swimmer had been pushed away from the shore. While one of the swimmers managed to return to shore, the other did not surface. Recovery efforts were initially unsuccessful, but the body of the swimmer that did not return to shore was later discovered two days later.

Wider weather episode

Sufficient moisture in combination with a shortwave impulse brushing by the area resulted in numerous strong thunderstorm wind gusts in addition to isolated instances of flash flooding.
