Kane County Chronicle | National Weather Service: 'Do not travel'

A blizzard warning issued by the National Weather Service urges travel to cease, at least until afternoon, calling the storm "a crippling and potentially killer blizzard." The warning says that "law-enforcement officials report that nearly every roadway is impassable and in many cases closed. ... officials are pleading for people to stay home and off roadways."

"Visibilities are so poor in open areas that motorists could become disoriented and unable to even see beyond the hood of their cars," the warning states. "Before considering getting on the roads this morning ... ask yourself if getting to your destination is worth risking your life. Conditions will likely slowly improve later this morning into the afternoon as winds subside and snow ends ... but until then, do not travel!"

It also warns that shoveling will become very difficult and potentially deadly, stating that after the 1999 blizzard, more than 40 people in the Chicago area died as a result of a heart attack while shoveling. "Do not underestimate the task at hand when shoveling," it says.

Later, wind chills will become a significant concern. The warning forecasts winds that could produce wind chills of -20 to -40.
