Here we go again. Another atmospheric river weather system is poised to move through the region late Thursday night into Saturday morning, resulting in periodic heavy rain, strong winds, and heavy snow in the mountains. A Flood Watch is in effect for the entire region from late Thursday night through Saturday morning. The effect Thursday will be mostly felt in terms of high winds, gusting to 40 mph or more by the afternoon. Rain and snow will likely start in the mountains late Thursday afternoon, with initial snow levels above 7,500’. The heaviest precipitation will come through very early Friday morning, and snow levels will gradually drop throughout the day, reaching Lake Tahoe level late Friday afternoon, and then possibly falling to the valley floors by Saturday morning.

There is a bit of a break Sunday before a weak system comes through Monday morning.

From a flood potential, the best advice given is if you live in an area that has been affected by flooding already this winter, it would be wise to keep your flood mitigation efforts in place. While it’s not likely there will be significant flooding on the mainstem rivers, smaller creeks and drainages could be susceptible to flash flooding.
