Sunday’s snow flurries continued into Monday morning and through the morning commute, causing dozens of accidents and slide-offs throughout the Treasure Valley.
Canyon County emergency dispatchers said late Monday morning that Caldwell Police Department and the Canyon County Sheriff’s Office had responded to a combined 39 accidents and slide-offs — and calls were still coming in. Ada County, saw less snow overnight, had 27 accident and slide-off reports since midnight, emergency dispatchers said.
The National Weather Service in Boise issued a winter weather advisory for Ada County that is in effect through 11 a.m. Monday. Meteorologist Katy Branham said the advisory focuses most on the Foothills north of Boise, though Boise proper will accumulate an additional 1-2 inches of snow through late Monday morning. A winter storm warning was also in place for the Boise Mountains.
According to Branham, light snowfall will continue until about noon on Monday, slowing down around the time most Treasure Valley residents begin their morning commutes. Though that could work to travelers’ benefits, Branham said black ice on the roads is still a potential hazard.

“Any time you have snow that’s melting through the day, (black ice) is a threat,” she said.
Busses in the West Ada School District were running about 15 minutes late Monday morning, according to a message sent by the district. Schools in McCall and Cascade were closed because of snow.
Several crashes on Interstate 84 before 7 a.m. Monday, including one eastbound near Black Cat Road, clogged the morning commute.
Joel Tannenholz, another NWS meteorologist, said Sunday’s overnight low would be 27 degrees. Monday’s projected high temperature is 35 degrees, though temperatures likely won’t climb above freezing until 1 p.m., Tannenholz said.
For some, the powdery storm wasn’t all bad news. Bogus Basin accumulated an additional 10 inches of snow since Friday, and officials at the ski resort said they anticipated even more on Sunday. Tannenholz said about 4 inches of snow was on the ground at the Boise Airport on Sunday afternoon — about 1/4 inch of that from Sunday morning.
Later in the week, Branham said, we could see even more snow.
“There’s a system trying to develop late Wednesday into Friday morning,” she said Sunday afternoon.
Details on that potential storm were still “sketchy,” Branham said.
