Fears of more floods – and possibly tornadoes – as another storm hits California

North sees strong winds while central coast at risk of ‘significant flooding’ as storm moves south toward Los Angeles

The latest in a series of wet winter storms gained strength in California early on Monday, with forecasters warning of possible flooding, hail, strong winds and even brief tornadoes as the system moves south over the next few days.

Gusts topped 30mph (48kph) in Oakland and San Jose as a mild cold front late on Saturday gave way to a more powerful storm on Sunday, according to the meteorologist Brayden Murdock with the National Weather Service office in San Francisco.
