No slow-melting snow will fall below the 3,500-foot mark. The rains will send water down the river all at once, Rowe said. Places most at risk for flooding this week include the Tehama Bridge at Los Molinos and Vina Woodson Bridge east of Corning, both in Tehama County.įarther south, the Sacramento River will likely spill over weirs built to help control flooding, especially at the Sutter Bypass west of Marysville and in Sacramento at the Fremont Weir between Woodland and the Sacramento Airport ― an area used for rice farming and other agriculture. However, as rainwater flows into the river and moves south, flood risk increases, he said. The Stockton area could get up to 3 inches of rain by Tuesday. The rain gets lighter in the southern Sacramento Valley, Rowe said. Those tributaries tend to flood faster than larger ones, so communities have less warning when flooding is imminent. Strong winds up to 40 mph in Redding and 50 mph in Chico could spread further rain and flood waters.Ĭommunities most at risk of flooding in the northern part of the valley include Cottonwood Creek in southwestern Shasta County and other small tributaries, Rowe said. Other parts of the north Sacramento Valley, including Shasta Dam and Shasta Lake, could get up to 6 inches. Redding could get up to 4 inches of rain by Tuesday, he said.
Rowe said Wednesday he expected heaviest rains to fall late Thursday night into Friday, possibly lasting until Saturday morning. Places at risk include those near creeks and small tributaries, urban communities and areas with poor drainage ― especially where snow is blocking drains and culverts, the weather service reported. The Sacramento River will likely reach just below the flood stage this weekend, but that could change quickly and water levels rise if most of the rain expected comes all at once.Īreas most likely to flood are located on the Sacramento Valley floor, but foothill communities located below 4,000 feet could see flooding too. “The entire Sacramento River is expected to rise at least into early next week.” said meteorologist Scott Rowe at the weather service’s Sacramento branch. The National Weather Service issued a flood watch that started Thursday afternoon and continues until Sunday morning for low-lying and urban areas, from Shasta Lake in the north to Stockton in the south.įlooding and rock and mud slides could block traffic on parts of Interstate 5, Highway 99 and other Northern California roads, according to the California Department of Transportation. * All work is scheduled to begin as listed but subject to change due to traffic incidents, weather, availability of equipment and/or materials, and construction related issues.Watch Video: Another moisture-packed storm targets California, brings atmospheric riverĪ warm storm bringing heavy rain and melting snow could cause Sacramento Valley waterways to flood this week.
