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 strong thunderstorm generated a weak tornado over Ventura Harbor (in Ventura county). Only very minor damage was reported.

The wider storm

A powerful winter storm brought significant rain, snow and wind to the area. Rainfall totals ranged from 1 to 2 inches across coastal and valleys areas with 2 to 4 inches in the foothills and mountains. With snow levels dropping to between 2500 and 3500 feet, significant snowfall was reported in the mountains (up to 1 to 2 feet) and even the Antelope Valley (4 to 8 inches). Numerous road closures due to winter storm conditions were reported, including Interstate 5 through the Grapevine as well as Highways 14 and 138. Additionally, thunderstorms generated a waterspout over the coastal waters as well as a very weak tornado over Ventura Harbor.
