By 8 o'clock this morning, the Ada County Sheriff's Office had already reported a dozen crashes and four slide-offs with injuries. Eagle Police also responded to a crash involving a school bus at the intersection of Palmer and West State streets.
The National Weather Service is forecasting snow for much of the day and into this evening. Precipitation in one form or another is expected to be a frequent visitor until Sunday.
Four to 8 inches of snow is expected in the Upper Treasure Valley today, and up to a foot is expected along the Foothills.
Forecasters remind travelers that a winter storm warning for heavy snow means that "significant amounts of snow will make travel dangerous." If you must travel away from the metropolitan area, keep an extra flashlight, food and water in your vehicle in case of an emergency.
