New post on http://twitter.com/caltransdist3 : TrafficAlert NO Chain Controls on I-80. Snow, ice and water on roadways = slippery driving conditions. Take it slow to avoid hydroplaning and loss of vehicle control. Sunny in the Valley but Winter Storm Warning until 11 p.m. Thursday! Be prepared for changing conditions. http://pic.twitter.com/2OjrMrGUid
