However, the Department of Water Resources say it won't be enough to put a real dent in the drought.
The Department said Wednesday before the storm began, readings showed the water content of the snowpack had dropped to 10 percent of normal statewide.
The state's reservoirs are also only a third full.
Earlier this month, Governor Jerry Brown declared a drought emergency.
Snow Water Equivalents Divided Per Region for Jan. 30
- Northern Sierra - 6 percent normal for this date
- Central Sierra - 15 percent normal for this date
- Southern Sierra - 14 percent normal for this date
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.
