What the National Weather Service wrote

Public reported a mudslide and rockslide due to heavy rain with vehicles stuck in the mud. Radar estimates 1-2 inches of rainfall for the event.

The wider storm

An upper level wave moving through N CA/NV provided plentiful forcing for storms to develop on July 30. In fact, showers lingered overnight the night before across portions of the Sierra and NE CA. These storms produced robust outflows with multiple areas of blowing dust and one true haboob/dust storm. We also had flooding that closed a roadway that afternoon/evening along US-395 near the Red Rock area.

Began near Boardertown (39.6814, -119.9998).
