Sound familiar? Commuters should leave early and take extra care Thursday morning.
The National Weather Service has issued a dense fog advisory Thursday morning for the Treasure Valley, West-Central Mountains and eastern Oregon's Baker County.
Visibilities could drop to as low as a quarter-mile or less at times. The advisory, which was issued at 6:15 a.m., is in effect until 11 a.m.
Several crashes were reported around the area as a result of the weather and/or road conditions:
At about 7:30 a.m., a pickup rolled over at Seamans Gulch Road near West Longbranch Lane near Hidden Springs. Ada County Sheriff's Office spokesman Patrick Orr said a 16-year-old driver and his or her passenger were headed toward Boise when the truck hit an icy patch. The pickup went off the road and rolled. Both occupants were wearing their seatbelts, and neither suffered serious injuries.
At 7:50 a.m., there was a report of a bicycle crash at 15th and Grove streets.
At 8:15 a.m., a one-vehicle rollover was reported at Chinden and Star roads. No more information was immediately available.
Orr said deputies are reporting slick conditions and poor visibility in many area of the county.
