SAN FRANCISCO (AP) — The National Weather Service has issued a rare tornado warning for Northern California’s Contra Costa County after a trained weather spotter reported seeing a funnel cloud.
The weather service says the cloud was seen about 9 miles south of Oakley and could touch down in a rural area of the east San Francisco Bay-area county.
It’s the second time in a week that a tornado warning has been issued. The first was issued Wednesday for Santa Clara county.
The weather service urged people to go to a basement or interior hallway or room and lie down.
