Weakened Tropical Storm Elsa still packing soggy punch

A weakened but resilient Tropical Storm Elsa was moving swiftly up the East Coast after killing at least one person in Florida Wednesday and injuring several others when a possible tornado struck a campground at a Navy base in southeast Georgia.

Some 60 million people were under tropical storm warnings and watches early Thursday, according to CBS news weather producer David Parkinson. The National Hurricane Center said Elsa's winds weakened to 40 mph as it made its way over South Carolina early Thursday. Elsa was expected to continue into North Carolina later in the day, pass near the eastern mid-Atlantic states by Thursday night and move near or over the northeastern United States on Friday.
