After Tornadoes Tear Through Michigan, More Storms Threaten Eastern U.S.

At least one person was killed on Wednesday as strong storms moved through Missouri, Illinois, Kentucky and Tennessee on Wednesday afternoon, bringing heavy rain, strong winds and hail in some areas. The severe weather arrived a day after widespread storms pummeled the Midwest, with tornadoes that tore through Michigan.

In Claiborne County in northeast Tennessee, one person was killed after a tree fell on a vehicle as storms moved through the area around 10 a.m. local time, according to the county’s office of emergency management.

As storms continued to move through a swath of the Midwest and the Eastern United States on Wednesday afternoon, the National Weather Service issued a string of tornado warnings in cities across Missouri, Kentucky and Tennessee. More severe storms were expected through the evening, according to forecasters.

About 18 million people were under either an enhanced or moderate risk of severe weather — the third and fourth levels of intensity, out of five — on Wednesday, according to the National Weather Service’s Storm Prediction Center.

“Don’t let your guard down!” the National Weather Service office in Nashville said on social media Wednesday afternoon. “We’re in the ‘lull’ right now before the main line tonight. Our environment is very unstable so any storm that develops ahead of the line this afternoon could turn strong to severe very fast.”

Here’s what to know about the storms:

• The most intense storms were expected to hit a corridor including the cities of Nashville and Clarksville, Tenn., with about four million people potentially affected by large hail, tornadoes and damaging winds.

• A wider area of about 17 million people from Texas to North Carolina, including the cities of Memphis, St. Louis and Little Rock, Ark., face an enhanced risk of severe weather.

• Heavy rain also prompted flash flood warnings on Wednesday for parts of Tennessee and Missouri. Forecasters said that flooding had already been reported in cities like Cole Camp and Lincoln in Missouri, and could spread to small creeks, streams, highways and other low-lying areas.

Nearly 50 tornadoes were reported from Oklahoma to Ohio over the past two days, as severe storms wrought damage throughout the Midwest.

The storms brought strong winds and caused power outages. About 28,000 customers were still without power in Michigan on Wednesday afternoon, according to PowerOutage.us.

Among the hardest hit counties was Kalamazoo, in southern Michigan, where officials said that tornadoes damaged nearly 200 mobile homes and winds were so strong that they lifted some homes away. At least 16 people were injured, the authorities said, though none seriously.

About 50 workers were rescued from a FedEx depot center in Kalamazoo County after a tornado wrecked the building and stranded them inside. The authorities in Oklahoma said a tornado that was up to two miles wide caused widespread destruction on Monday, killing one person in Barnsdall, and damaging up to 40 homes in the small town.
