Tornado death toll in Joplin, Mo., at 139

JOPLIN, Mo. -- City officials raised the death toll from last Sunday's tornado in Joplin, Mo., to at least 139 and state officials say 100 people are still missing.

A teen believed to have been ejected or sucked from his vehicle on the way home from graduation when the tornado struck is among the dead. Will Norton was found in a pond near where his truck was located, his family said.

The tornado -- an EF-5 packing 200-mph winds -- was the deadliest since 1950. More than 900 people were injured.

The tornado death toll for 2011 is now 523, making this the deadliest year for tornadoes since precise records began being kept in 1950, based on an assessment of figures from the National Weather Service. Until now, the highest recorded death toll in a single year was 519 in 1953.

There have been 1,333 preliminary tornado reports in the United States through Friday, officials said, while the average number of confirmed tornadoes in a single year during the past decade has been 1,274.-- AP
