Waves near the San Francisco Bay Area could reach up to 25ft (7.6 meters) on Friday, parts of southern California were at risk of flooding, and avalanches could hit the Lake Tahoe area, officials warned. Residents were told to be ready to evacuate the mountain town of Wrightwood about 80 miles (130km) north-east of Los Angeles because of mudslides. Atmospheric rivers carried massive plumes of moisture from the tropics during one of the busiest travel weeks of the year. The storms were blamed for at least two deaths earlier in the week. The system brought the wettest Christmas season to downtown Los Angeles in 54 years, the National Weather Service said.
