February 13, 2019 02:41 PM
Wednesdays atmospheric river storm brought painfully slow commutes across Northern California, some flooding in common trouble spots in Sacramento and a rare layer of thick snow in the northern Sacramento Valley.
The wet weather broke a daily rainfall record in Sacramento, with 1.6 inches of rain recorded at the Sacramento Executive Airport over 24 hours. The last record for Feb. 13 was set in 1979 with 1.22 inches.
But the states network of flood control dams and levees appeared to handle the deluge without major problems.
The National Weather Service issued a flood warning Wednesday morning for the Sacramento Valley, and it was expected to remain in place until 6 p.m. Thursday as heavy and moderate rainfall was forecast to continue through Thursday.

Discovery Park near downtown Sacramento was expected to flood Wednesday evening. Flooding routinely happens this time of year when officials release water into the American River from Folsom Dam to make space in the lake to catch mountain storm runoff.
Park rangers had been making the rounds in advance of the Folsom releases, urging more than 150 people camping in Discovery Park to find higher ground, said Kim Nava, a spokeswoman for the park.
Howe Avenue and Watt Avenue river access to the American River Parkway were closed Wednesday and will remain that way until the American River recedes.
Elsewhere in Sacramento County, the usual flood prone areas around Arcade Creek, the Cosumnes River and in Rio Linda were being closely watched. County officials , but major flooding wasnt reported by midday.
Its routine right now, said Matt Robinson, a spokesman for Sacramento Countys Department of Water Resources. If we have another storm that comes behind it, things could change.
The Sacramento area has already had 3 inches of rain this month. The normal for all of February is 3.69 inches.
Further north, a colder than normal storm brought up to a foot of snow in some lowland areas of Shasta County, leading to power outages as trees toppled, local residents reported.
The National Weather Service issued a winter storm warning for eastern and northern Shasta County as well as western Plumas County, Burney Basin and the West Slope of the northern Sierra Nevada. The warning is in effect until 4 a.m. Saturday and warns that travel will be hazardous and sometimes impossible due to high winds and a further expected 3 to 6 feet of snowfall.
It is a mess, said Nadine Bailey, an Anderson resident whose Facebook page featured a picture of downed limbs in her driveway and about 8 inches of snow on the ground. The snow was so thick Wednesday . The freeway was expected to stay closed for much of the afternoon.
Chain controls were also in place for most of the Sierras as of Wednesday afternoon, with the exception of Interstate 80, which had chain controls for trucks only.
In Sacramento, the rainy roads made things a mess for drivers Wednesday, with numerous spin outs, accidents clogging lanes and minor roadway flooding throughout the day. There may not be much of an improvement Thursday. in Sacramento will bring 1/4 to 1/2 inch of rain to the city.
Beyond the Sacramento metro area, the Russian River could cause problems in Guerneville and the Napa River was likely to hit flood stage in St. Helena, said Alan Haynes of the federal California Nevada River Forecast Center.
The burn scar area around Paradise, site of last Novembers Camp Fire, could see some flooding if the rain intensifies, Haynes said.
Managing the storm has been made easier for Californias flood managers because most of the states major reservoirs still have ample room to accommodate storm runoff, Haynes said.
Shasta Lake — the states largest reservoir — was 69 percent full Wednesday. The second largest, Lake Oroville, which is being kept deliberately low this winter because repairs to the dams fractured spillways are still not finished, was 45 percent full, California Department of Water Resources figures show.
Folsom Lake is 62 percent full. On Tuesday, the dams federal managers opened its dollar 900 million auxiliary spillway for the first time to make room in the lake.
Theres not another release from the new structure scheduled yet this week, but dam managers expect to use the new spillway often in the months and years ahead to help manage Folsoms levels, said Erin Curtis, a spokeswoman for the U.S. Bureau of Reclamation, which manages the dam.
Meanwhile, Wednesdays storm bumped the index of precipitation in the northern Sierra Nevada to 106 percent of historical average, according to state figures. The statewide Sierra snowpack is 30 percent above normal.
All told, the states water outlook is on track to be at or a little above average, said Michael Anderson, a climatologist with the state Department of Water Resources.
