Tornado warning wakes San Francisco: 'Take cover now'
A tornado warning was issued for San Francisco early Saturday morning due to a severe thunderstorm capable of producing a tornado. The warning, which was the first of its kind for the area, prompted residents to take cover. Although the storm caused some damage and power outages, the tornado threat subsided quickly as the storm moved over the city's hilly landscape. By the afternoon, scattered showers were expected, with a possibility of sunshine on Sunday.
