(CNN) -- The winter storm that dropped more than 18 inches of snow in parts of the Midwest has fled toward Canada, weather forecasters said Thursday, but more snow, high winds and bitter cold still plagued parts of the country.
Wind gusts reached 60 mph in Toledo, Ohio, and 58 mph in Fort Wayne, Indiana. Temperatures dropped to 16 degrees in Detroit, Michigan, while in the South, temperatures were in the 30s and 40s, but dropping, the National Weather Service said. It was in the 40s in New Orleans, Louisiana.
A blizzard warning was still in effect for Michigan, which could see as much as eight more inches of snow Thursday, forecasters said.
Lake effect snow, which occurs when a mass of cold air moves over a body of warmer water, was forming over Lake Michigan, resulting in as much as a foot of snow in southern Michigan, forecasters said. The same phenomena were occurring over the relatively warm waters of Lake Ontario and Lake Erie, said CNN meteorologist Rob Marciano.
Several states reported storm-related deaths.
In Yale, Iowa, an elderly man was discovered dead Wednesday outside his truck, said Bret Voorhees, spokesman for the state's Homeland Security and Emergency Management Agency.
A 28-year-old woman was killed in Omaha, Nebraska, Tuesday night when a truck plowing snow in a parking lot backed into her, police spokesman Jacob Bettin said. She was pronounced dead at the scene.
In north-central Arizona, about 30 hunters became stranded in freezing weather, and search missions were launched Wednesday afternoon at various locations in Coconino County, said Sheriff's Office spokesman Gerry Blair.
Some of the hunters contacted authorities on cell phones, Blair said. Family members of others called authorities when their relatives did not come home on time. The searches were to continue into the evening, he said.
