Extreme weather continued Tuesday, causing flooding in the Florida Panhandle and a deadly twister in Alabama. Jonathan Serrie reported this morning from hard-hit Tuscaloosa, where a massive tornado left more than 60 people dead three years ago.

On Tuesday, University of Alabama swimmer John Servati was killed when a wall collapsed on top of him in an off-campus house. Servati, 21, was a business major on the dean's list.

LOUISVILLE, Miss. –  Florida Gov. Rick Scott declared a state of emergency Wednesday after his state was hit with more than 20 inches of rain in the past 24 hours, killing at least one and leaving others stranded in their houses and cars in the state's Panhandle.

Escambia County spokesman Bill Pearson told The Pensacola News Journal that at least one person died and several others were stranded by floodwaters in Escambia and Santa Rosa counties. The circumstances surrounding the death were not immediately known. 

Pearson said fire rescue crews aren't able to respond to some calls early Wednesday because of road flooding around Pensacola. He said some people have climbed into their attics because of rising waters. 

"We are asking people to stay off the roads," Pearson told the newspaper.

The county is moving boats and jet skis from beaches to streets for rescues. The Florida Fish and Wildlife Conservation Commission is lending boats and officers to help.

Schools and most government offices in the area are closed Wednesday.

Tamara Fountain, spokeswoman for the city of Pensacola, told The Pensacola News Journal that the city activated its Emergency Operations Center in response to the flooding.

"People are being rescued from their homes and cars," Fountain said. "People are still out driving. They need to stay in." 

As much as 15 to 20 inches had fallen in Pensacola in a 24-hour period, National Weather Service meteorologist Phil Grigsby in New Orleans said Wednesday morning, with a few more inches expected. Grigsby said aerial rescues were planned, and the county moved boats and jet skis from the beaches to the streets to help. A portion of Interstate 10 was closed.

"We've seen pictures that people are posting with water halfway up their doors, front doors," Grigsby said. "It's going to be a big cleanup, looks like."

The rain and blooding was the latest wallop of a storm system that still packed considerable punch days after the violent outbreak began in Arkansas and Oklahoma. At least 35 people have been killed in that storms that started Sunday and spread from Oklahoma to North Carolina.

At least four possible tornadoes were reported late Tuesday in North Carolina, but there were no immediate reports of injuries. The storms hit especially hard in places such as Arkansas' northern Little Rock suburbs and the Mississippi cities of Louisville and Tupelo. Arkansas, with 15 deaths after a tornado blasted through Sunday, and Mississippi with 12 deaths from Monday's storms, accounted for the brunt of the death toll.

"We will overcome this," Louisville Mayor Will Hill said against a backdrop of hundreds of damaged buildings, including two hilltop churches pounded to rubble. "We're going to work together."

Authorities in Louisville searched until dark Tuesday for an 8-year-old boy missing since Monday's large tornado that killed his parents and destroyed the home where they lived. Though searchers didn't rule out finding the boy alive, officials were describing the process as one of "recovery."

Besides the dead in Mississippi and Arkansas, at least three died in Alabama, two in Iowa and one in Oklahoma.
