Sunday's storm wreaked its havoc on creeks, streams and riverbeds in the Napa Valley, as elsewhere in the North Bay. The day's rainfall was 1.6 inches in a 24 hour period in the City of Napa Corp yard, but significantly higher elsewhere - up to 3.17 inches at the Dry Creek Fire Station in the mountains to the west.
The City of Napa released a report at 5:49 p.m., with the information below, including notice that Veterans Memorial Park, the Riverfront Promenade, Oxbow Preserve Park and Trancas Crossing Park are closed until further notice. The river trail between Trancas and Lincoln is also closed, due to a sinkhole.
Conditions were much as they were three weeks ago. With the passing of the storm, water levels on creeks and streams are now dropping. However, a Flood Warning is in effect for the Napa River until 10:00 p.m. tonight.
The National Weather Service projects that the river will crest at 26.7 feet in the area of Oak Knoll Avenue at about 10:00 p.m. That level is 1.7 feet above flood stage. Oak Knoll Avenue is about five miles north of the City of Napa.
Near St. Helena, the river is projected to crest at just over 17 feet this evening, around a foot over flood stage of 16 feet, according to the National Weather Service.
In the City of Napa at the Lincoln Avenue bridge, the river level was 11.24 feet at 4:00 p.m. and rising. The river is expected to crest in this area around midnight tonight. City projections indicate that the Napa River will reach or exceed the monitor stage of 16.5 feet but will not reach flood stage of 18.5 feet.
As a precaution for public safety, the City advises residents and businesspersons in low-lying areas along Lincoln Avenue, Imperial Way and Taylor Street to monitor the river level from 9:00 p.m. tonight on. To track rainfall amounts and river and creek levels, go to napa.onerain.com.
The City will issue further information after monitoring the predicted crest at Oak Knoll at 10:00 p.m.
