Sacramento will experience dense fog for part of Monday before a series of three winter storms roll through Northern California later this week.
The National Weather Service urges Sacramentans to use Monday and Tuesday to prepare for another wet period. Water accumulated in major flooding areas in the region last week, including the South Sacramento community of Point Pleasant, the city of Elk Grove and the Dry Creek area of Rio Linda.
Flooding is expected to recede early this week, said Chris Hintz, meteorologist and forecaster for the National Weather Service in Sacramento.
“We are getting a little break here, so that is allowing the waters to recede,” Hintz said.“We will have to see how things accumulate through the week.”
Expected rain levels for Sacramento will reach almost 2 inches by Saturday. The Central Valley should see 1 to 3 inches of water and the foothill region may get up to 5 inches, Hintz said.
Snow levels in the Sierras will reach 5 to 6,000 feet Wednesday, lowering to 4,000 feet Thursday. There will be periods of hazardous weather in the mountains Wednesday through Monday, Hintz added.
All California National Parks are offering free entrance Monday, in honor of Martin Luther King Jr. Yosemite National Park will be sunny Monday, with a high near 46. Sequoia National Park will be sunny with highs in the mid 40s.
