Winter weather-related alerts from the National Weather Service (NWS) are in place for multiple U.S. states as of early Saturday, with up to two feet of snow expected in some parts of the country.
The agency warns of hazardous driving conditions across the affected areas, with travel in some parts expected to be “impossible.” Winter storm warnings, issued when “a significant combination of hazardous winter weather is occurring or imminent,” are in place for central Iowa, western Colorado, northwest Washington, as well as parts of Idaho, Montana, Utah, and Wyoming.
