Thick fog is blanketing the Sacramento area.
Mike Smith with the National Weather Service office says in some areas, visibility is down to zero Thursday morning.
"There's a dense fog advisory this morning for the Southern Sacramento Valley, the Delta and the Northern San Joaquin Valley, it's fairly widespread this morning," Smith says.
Smith says the dense fog advisory is in effect in Southern Sacramento and the Delta until 11 A-M and through the San Joaquin area until noon. He says a high pressure ridge has allowed moisture to build up, helping to create the dense fog.
As for rain-- there's a possibility of that over the next few days, but not so much for the Sacramento area-- more for the far Northern part of the state.
As of 7 a.m., visibility was down to less than one quarter of a mile in some parts of Sacramento. Authorities are urging motorists to slow down.
Are you driving through the fog this morning? Slow down to increase reaction time and see and be seen by turning on the low-beam headlights.— CHP Headquarters (@CHP_HQ) January 15, 2015
