Damage as recorded

Where the report was made, with tornadoes recorded within 15 miles over the years.

What the National Weather Service wrote

Heavy rain washed out a section of a dirt road approximately three-quarters of a mile north of Newport on the west side of the Pend Oreille River. Recent road work by the planned utility development installing a fiber-optic cable along this section of the roadway likely made the hillside more susceptible to the washout. Property damage was estimated.

The wider storm

Post frontal showers developed in the wake of a cold front late in the afternoon across southern Pend Oreille County. A shallow layer of instability off the surface and ample low level moisture resulted in quick developing convective cells that produced heavy rainfall and pea sized hail.

Began near Wolfred (48.2243, -117.0827).
