The AP reports this as "the 2nd deadliest" tornado outbreak since the Great Tri-State Tornado of 1925 when at least 747 people were killed.
That tornado or now thought to be a series of tornadoes raked an area from eastern Missouri into southwestern Indiana- according to Wikipedia.
One ef-5 tornado has been confirmed by the National Weather Service (NWS)- the twister that struck and virtually wiped-out Smithville Mississippi.
That was the first EF-5 tornado in that state since 1966- 45 years ago.
NWS survey teams continue to check the numerous tornado tracks in the 6 other states also affected by the tornado swarm.
