April's 300 confirmed tornadoes so far is twice as many as for all of 2010 and has broken a 40-year US record.
The heavy rains have swollen rivers and in southern Missouri an earthen levee protecting the small town of Poplar Bluff is said to be leaking in at least 30 places.
The effects of bad weather is an all-too familiar scene in America’s south and midwest. However, the tornado season has come early with full force and meteorologists say it is far from over.
The forecast is for the front to move on to the east coast, where tornado watches have been posted.
