Five people died in five separate traffic crashes on Wednesday as winter weather, including ice storm conditions, blasted parts of northern Colorado.

Investigators on Wednesday night could not definitively say that all five fatal crashes were caused by adverse weather, but weather did play a role in some.

“Certainly weather is playing a factor in terms of treacherous conditions,” said Trooper Josh Lewis, a State Patrol spokesman.

“It is out of the ordinary,” Lewis said of the multiple fatal crashes.

A winter weather advisory, posted by the National Weather Service, for wide areas of northeastern Colorado, remains in effect until 8 a.m. Thursday and calls for freezing drizzle and ice accumulations up to one-tenth of an inch in some areas.
