NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Small tornado touched down in an open field with no damage reported.

The wider storm

An upper level low pressure system off the coast of southwest Oregon slowly moved inland the afternoon and evening of August 13th. This lead to another round of showers and thunderstorms for most of the forecast area. Heavy rain and large hail were the main severe weather threats on this day. But an isolated tornado was reported near Rattle Snake Mountain.

Began near North Prosser (46.3200, -119.8000).
