Tornadoes and Tropical Storm Arthur Slam US

A severe weather outbreak swept across the central and southern United States, with tornadoes causing destruction in Illinois and Tropical Storm Arthur making landfall along the Gulf Coast.

The National Weather Service warned of 'catastrophic' flooding in Alabama, where up to 15 inches of rain could fall.

In Illinois, buildings were destroyed and vehicles overturned, while Arthur brought storm surge and heavy rain to Texas and Louisiana.

The dual events mark a dangerous start to the Atlantic hurricane season.
