A fast thinking Mississippi weatherman ordered a news station evacuation on April 28 while cameras were still rolling.

After warning of a tornado ripping through Tupelo, where the station is located, WTVA chief meteorologist Matt Laubhan ordered an immediate evacuation.

"Everybody, basement, now! Basement now! Let's go," Laubhan directed before rushing off set.

Off-screen, viewers hear him exclaim, "Now!"

Other news station employees can be heard saying "Let's go," and calling out staff members' names.

Laubhan later tweeted, "We are safe here. How is it in your area? Send us pictures and updates by using #wtva42814."

Before the evacuation, Laubhan warned of a tornado emergency in Lee County, and a tornado touchdown in west Jackson.

Seven people were killed in Mississippi yesterday, six of them in Winston County. One woman was killed in Tupelo after her car was either blown off the road or hydroplaned. Mississippi Governor Phil Bryant declared a state of emergency in advance of Monday's storms.

Two people were killed in Tennessee's Lincoln County on Monday night after a tornado hit their home.

Alabama officials confirmed two deaths in their state. A total number of reported deaths remain unconfirmed.

Winston Medical Center senior emergency room physician, Dr. Michael Henry, illustrated how quickly a tornado can strike.

"We thought we were going to be OK, then a guy came in and said, 'It's here right now,'" Dr. Henry, told the Associated Press.

"Then boom ... it blew through."

The tornado tore holes in the Louisville, Mississippi hospital's roof.
