A dense fog advisory is in place until noon Friday, and more rain and snow is expected in Kern County through the weekend.
Visibility will be a quarter of a mile or less, according to the National Weather Service. Some places will have visibilities of less than 500 feet.
The fog comes after a Thursday of wet conditions. El Tejon Unified School District was closed Thursday because of wet, slushy conditions in the Lebec area.

Kern County Superintendent of Schools Director of Transportation Sheryl Boe said each district's superintendent makes the call about whether to close for the day or open a couple of hours later if there's inclement weather. Each district has its own policy in place regarding what time decisions are made, but the general recommendation is to have it made by 6:30 a.m.
"It's kind of a guessing game," Boe said.
