The National Weather Service's tornado warning is now expired, and the threat of severe storms has diminished.
A tornado warning was issued just after 2 p.m. Tuesday for west-central Butte County, extreme northeastern Glenn County and south-central Tehama County by the National Weather Service in Sacramento. The tornado warning since expired.
At 2:12 p.m., National Weather Service doppler radar detected a severe thunderstorm capable of producing a tornado near Vina or six miles east of Corning.
When a tornado warning is issued based on the doppler radar, the National Weather Service says it means that a strong rotation has been detected in the storm.
Video from the area showed one possible tornado on the ground, that was since confirmed by the National Weather Service to be an EF-0 based on a preliminary survey. A second funnel cloud was reported, but has not been confirmed.
