RENO, Nev.—A massive storm system stretching from Northern California to Nevada sent rivers overflowing and toppled trees—prompting evacuations, school cancellations, road closures, and warnings of dangerous mudslides for hillsides parched by wildfires last summer.
Some California ski areas closed for the second day Monday in the Sierra Nevada over avalanche concerns and power outages, with forecasters warning that more snow and rain was on the way.
In Nevada near Reno, Nevada National Guard high-water vehicles were deployed to help people evacuate from a town.
Over the weekend, toppled trees crashed against cars and homes and blocked roads in the San Francisco Bay Area, and officials rescued stranded motorists from cars stuck on flooded roads.
A giant tree fell across a highway in Hillsborough to the south of San Francisco, injuring a driver who couldn’t break in time and drove into the tree. And a woman was killed Saturday by a falling tree while she took a walk on a golf course.
In California’s famed wine country, the Napa River jumped its banks and flooded vineyards. Rivers in Sonoma Valley north of San Francisco and in Reno, Nevada, both overflowed their banks late Sunday with officials saying the waterways could remain at flood stage for days.
