We are watching the North Bay closely for the threat of flooding in areas. Any shift in the track of this storm -- whether north or south -- would mean a change in the rainfall totals and a change in the SIS.

The heaviest snow in the Sierra expected to fall Saturday afternoon and evening. A new Winter Storm Watch is posted.
