UPDATE: 1:00 P.M.

Douglas County has resumed its normal street patrol operations.

At the same time the Nebraska State Patrol says, starting Saturday, travel throughout the state is not advised. 

UPDATE: 10:45 a.m.

This just in from the Douglas County Sheriff:

"Due to the icy roads and numerous accidents, the DCSO will only respond to injury accidents.  If you are involved in a non-injury accident, we ask that you move your vehicle off the roadway and exchange information.    We will inform the public when this restriction is lifted."

INITIAL REPORT: 9:30 a.m.

Even before a predicted 2-8 inches of snow hits the Omaha metro, slippery streets and fog already find police urging drivers to take it slow.

As of 9 a.m. Omaha Police tweeted "Very slick this morning. Don't drive if you don't have to. If you do have to then slow down and brake early because you're going to slide at many intersections."

There are already half a dozen accident reports at several metro intersections from all parts of the area.

Several of the metro "city cams" are shrouded in fog, making viewing impossible. A "dense fog warning" is in effect until noon Friday (the photo above is the Nebraska Department of Transportation camera at Highway 75 and Cornhusker Road at 9 a.m. Friday).

A winter storm warning is in effect starting at 3 a.m. Saturday until noon Sunday, bringing winds gusting up to 35 mph, wind chills as low as 25 below zero, and that wide range of snowfall.
