Rainfall in Napa County is expected to reach torrential levels Sunday as a National Weather Service flood warning continues in the Napa and St. Helena areas.

A storm that entered the North Bay late Saturday is forecast to bring 3 to 7 inches of precipitation to the Napa River corridor, mainly before 4 p.m., and with higher-elevation areas getting the heaviest downpours. Strong west-southwest winds should blow at 18 to 23 mph, gusting as high as 30 mph.

The high temperature at Napa County Airport is expected to reach 62 degrees, with a nighttime low of 46.

Flood warnings along the Napa River will remain in force through Sunday night.

North of Napa near Oak Knoll Avenue, the crest is expected to reach the local flood stage of 25 feet on Sunday afternoon. In the St. Helena area, the peak river level is predicted to be 17 feet, a foot above flood stage.

Rains are expected to taper off after about 10 p.m., giving way to partly sunny skies Monday before a chance of more rain starting late Monday night.

Here is the five-day temperature outlook for Napa:


Monday: 61 / 47 — chance of rain after 10 p.m.

Tuesday: 61 / 51 — 50 percent chance of rain

Wednesday: 63 / 46 — chance of daytime rain

Thursday: 62 / 41

Friday: 59 / 41
