Mike Smith is a meteorologist with the national Weather Service in Sacramento.
"Well, obviously it's a over a once in a 100 year event, so it's fairly rare," he says.
Smith says Sacramento is also likely to see a record high temperature today -- at 70 degrees. The old record was 69.
"Typically this time of year in Sacramento, we get right around the mid 50s and we're expecting a high today of 70s so that's about 15 degrees above normal," Smith says. "Some places in the northern valley will be pushing about 20 degrees above normal for this time of year."
January brought above-average rainfall and snow to much of California, partly due to El Niño. But forecasters say the ocean warming condition is "taking a break" for the next week or longer.
The U.S. Drought Monitor says, other than a slight reduction in exceptional drought in the northern Sierra, it needs more time to assess impacts of the recent moisture on California's long-term drought.
California regulators have made modest adjustments to water conservation requirements for cities.
The second measurement this winter of snowpack in the Sierra Nevada was 130 percent of average. State water officials say the snowpack will help reservoir recovery.
California's water conservation rate dropped to 18 percent in December. But water regulators say the state continues to meet its long term goals.
