Tropical Storm Karen could strengthen, snow storm out west - Oct 4th, 2013 - National
Tropical Storm Karen is expected to pound the northern Gulf Coast over the weekend and it could strengthen to a weak hurricane. People in parts of Alabama, Mississippi and Louisiana are being told to prepare for the storm. A state of emergency already has been declared in Louisiana and Mississippi.
Strong storms are moving into the Midwest, dumping heavy snow in South Dakota, spawning a tornado in Nebraska and threatening dangerous thunderstorms from Oklahoma to Wisconsin.
A foot of snow had fallen by Friday morning in western South Dakota's Black Hills. Some schools canceled classes. As much as 30 inches of snow could fall in the area.
The National Weather Service says the fall storm is one of the most intense to hit the area in a long time.
