The path drawn at its surveyed width of 20 yards (0.01 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

EF0 tornado began in the field just southwest of Roseville, but did not cause damage until it reached the Pleasant Grove Blvd housing developments in West Roseville. The tornado winds were estimated to be 75-85mph. Several windows were blown out amongst the houses, 25-30 feet of fence was blown down, projectile damage was found to stucco. The tornado lasted approximately 5-10 minutes.

The wider storm

A trough over the eastern Pacific dropped southward over the region bringing a series of shortwaves across interior Northern California. These shortwaves brought enough instability and moisture to produce tornadic supercells to interior NorCal. One tornado was reported on March 25th and five tornadoes were reported on March 26th. The trough also brought heavy snow to the Northern Sierra Nevada and Western Plumas County, mainly Wednesday and Wednesday night (March 26) with snow levels dropping to 4000-5000 ft.

Began near Riego (38.7624, -121.4164).
