An approaching Pacific storm with mild temperatures and lots of rain could cause the threat of flooding. The National Weather Service says some small streams may run full and rain and snow melt may pond in low lying areas. A colder storm reaching the area by Saturday afternoon could stop any further snow melt and run off. Snow is predicted in the higher elevations, with the heaviest snowfall in the Lake Tahoe area north. Strong winds are expected with this latest storm. Heavy rain with snow is expected in the mountains and will spread across the region Saturday.
The National Weather Service has issued a winter storm watch for Saturday evening and Saturday night for the Sierra, from Yosemite Park, south.
A series of storms last week dumped up to ten feet at some of the higher elevations. Forecasters say the approaching storm could add another foot or two to the snowpack in some locations.
The Reno-Carson City area is under a high wind advisory for today, and a high wind watch tomorrow. The weather service says snow levels will begin high, but lower to the valley floors of western Nevada by tomorrow afternoon. Another storm is expected to reach the Sierra Nevada Monday afternoon with the possibility of significant mountain snow. A chance of snow remains in the forecast through New Year´s Day.
