SACRAMENTO (CBS13) -- The first in a pair of strong storms is bringing a new round of heavy rain and high winds, prompting some flooding concerns that will last until Thursday night.

The first storm arrived overnight and is bringing rain, snow and heavy winds.  With a number of local creeks and waterways already running high due to recent rainfall, the National Weather Service says some areas could see rivers reach flood stage.

The second storm system will hit before the region gets much of a break from the first storm, and officials expect some flooding in the Yolo bypass near Lisbon, which is under a flood warning until further notice.

The sodden ground could also trigger more problems when the high winds arrive. A number of trees have fallen around the interior valley over recent days, with few reported injuries, but experts say there is a strong chance that more trees will be unable to stay rooted in the coming storms.

The higher elevations of the Sierra will also likely see even more snowfall. Moderate to heavy snow is expected through Friday morning, which could cause serious problems for drivers attempting to travel through the mountain passes. Chain controls are expected and road closures are likely.

Sierra residents are also advised to be prepared for power outages.
