New post on http://twitter.com/caltransdist3 : TrafficAlert I-80 chain controls still in effect DLI to Alta. Weather has been changing rapidly from wet to dry and back again. Looks like the Sierra is in for some wet/snowy weather for the rest of the afternoon per the NWS radar. Be prepared for winter driving conditions! http://pic.twitter.com/WYp4Ek64jq
