NOAA's preliminary estimate is that there were 305 tornadoes during the entire outbreak from 8:00 a.m. EDT April 25 to 8:00 a.m. April 28, 2011.

NWS created a table to provide clearer insight into the number of tornadoes.

Each of the three categories in the table below has different levels of confidence/accuracy.

There were 340 fatalities during the 24-hour-period from 8:00 a.m. April 27 to 8:00 a.m. April 28.

The Tuscaloosa-Birmingham tornado during the April 2011 event caused at least 65 fatalities.

This tornado had a maximum width of 1.5 miles and a track 80 miles long.

These are the most fatalities from a single tornado in the United States since May 25, 1955, when 80 people were killed in a tornado in southern Kansas with 75 of those deaths in Udall, Kansas.

The deadliest single tornado on record in the United States was the Tri-State tornado (Mo., Ill., Ind.) on March 18, 1925, when 695 died.

Ongoing (preliminary) List of Tornadoes by EF Rating (EF3 to EF5):

EF5: 2
EF4: 11
EF3: 21
