Preliminary reports show more than a dozen tornadoes touched down Sunday

There were nearly 40 reports of tornado damage across the southeast Sunday from at least 13 different tornadoes.

The storms killed at least 23 people in Alabama, including children. The youngest reported victim is just 6 years old. It is the most people killed by tornadoes in a single day since the Moore, Oklahoma, EF-5 tornado that killed 24 people in 2013.

The National Weather Service sent storm survey teams out across Alabama, Georgia and Florida and will take the next several days to estimate the strength of each tornado.

So far, preliminary reports from survey crews with the National Weather Service show more than a dozen tornadoes touched down Sunday. Here's the full list:

• EF-1 tornado in Macon County, AL
• EF-2 tornado in Leon County, FL
• At least EF-2 damage in Talbot and Harris counties
• EF-2 tornado in Ellerslie, GA (may be same tornado as above)
• EF-2 tornado in Cairo, GA
• EF-2 tornado in Crawford County, GA (became EF-1 tornado in Peach County, GA)
• EF-4 tornado in Lee County, AL
• EF-1 tornado in Pine Mountain, GA
• EF-1 tornado in Twiggs County, GA
• Tornado in Washington County, AL
• EF-1 tornado in Davisboro, GA
• EF-1 tornado in Washington County, GA
• EF-2 tornado in Barbour County, AL
• At least EF-1 tornado in Eufala, AL

In Georgia, it’s likely going to be the worst tornado outbreak since 41 tornadoes ripped across the state Jan. 21-22, 2017.

In Alabama, rescuers began tearing through the rubble of mobile homes and houses Monday in search of survivors of the powerful tornado that tore through the southeastern part of the state. The trail of destruction was at least half a mile wide.
