LAKE COUNTY, Calif. – Heavy rainstorms forecast for this week are expected to push Clear Lake well above the flood stage, with the National Weather Service issuing flood and wind warnings.

The National Weather Service said two primary rainstorms are anticipated. The first began moving across Northern California Monday night and throughout Tuesday, with the second expected on Thursday.

The warm and potentially very wet storms are expected to bring heavy rain overnight and throughout Tuesday, the agency said.

On Tuesday in particular, the National Weather Service said that storm is expected to be a “once every five to 10 years” rain event across portions of Northern California.

Those storms will be followed by continued showers through Saturday, with a break in the rain expected into early next week, according to the specific Lake County forecast.

Due to the storms and rising lake level, the National Weather Service issued a flood watch for much of Lake County that went into effect on Monday night and will continue until 4 p.m. Friday.

A wind advisory also has been issued for Lake County from 12 a.m. to 12 p.m. Tuesday.

The National Oceanic and Atmospheric Administration on Monday night issued an update on Clear Lake's depth predicting that the lake will move beyond the 9-foot Rumsey flood stage late Wednesday.

The lake was at 8.25 feet Rumsey late on Monday night, according to the US Geological Survey.
