The latest series of powerful winter storms dumped more heavy rain on an already flooded San Diego area and dumped snow on some mountains — and more rain is expected on Wednesday.
The low pressure system will bring another round of widespread rain with a slight chance of thunderstorms Wednesday night and early Thursday as more snow falls in our local mountains, the National Weather Service said.
By midday Wednesday, we may see a break in the rain with mostly cloudy skies and a chance of some showers. “We will still have passing showers this afternoon,” NBC 7's Sheena Parveen said. A separate, much smaller weather system could bring more rain on Thursday and Friday.
Over the course of three days that ended late Tuesday morning, dark humidity levels dropped anywhere from a few hundredths of an inch to nearly 7 inches across the San Diego area, the National Weather Service reported. See rainfall totals here.

- Julian Union Elementary School District
- Julian Union High School District
- Mountain Empire Unified School District
- Spencer Valley School District
- Warner Unified School District
Snow levels dropped to 4,000 feet Tuesday night and another round of snow was expected Thursday night, the weather service said. By Thursday morning, there is expected to be another 2 to 6 inches below 5,000 feet, 6 to 10 inches from 5,000 to 6,000 feet, and 10 to 16 inches from 6,000 to 7,000 feet.
On Tuesday, sightings of clouds rising in the sky heading northeast over Chula Vista prompted the National Weather Service to issue a tornado warning — a local rarity — for parts of the South Bay and East County. As of 12:45 p.m., when the warning expired, there were no reports of any tornadoes making landfall, according to the federal agency.

Gavin Newsom declared a state of emergency in Southern California due to the expected severity of the storm, which so far has been significantly more severe in areas north of San Diego County.
