The path drawn at its surveyed width of 2 yards (0.00 mi) — zoom in and the swath grows to true scale. 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

A funnel cloud briefly touched down near this location with no damage reported. Location is estimated based on radar. Tornado width is also estimated.

The wider storm

Low pressure formed off the coast of California and tapped into tropical moisture which lead to widespread Valley rain, mountain snow, and eventually even thunderstorm development over interior northern California. Valley rain amounts generally ranged from 0.25 to 1.0 inch of rain while foothill locations received 1.0 to 4.0 inches of rain. High elevation mountain snow was bountiful too with most sites reporting 1 to 2 feet of snow. The next day, behind the main front, widespread showers and thunderstorms developed on Nov 19.

Began near Dugan (38.6300, -121.0000).
