West Virginia Gov. Joe Manchin has activated 300 National Guard troops to help residents in the state's southern coalfields recover from weekend flooding.

Floodwaters have closed roads and damaged hundreds of structures.

The 300 guardsmen are in addition to the 30 Manchin activated Saturday.

In the Midwest, nearly 100,000 customers in Illinois and Missouri are still without electricity, days after a wave of deadly storms socked the region. The storms are blamed for at least seven deaths in Illinois, Missouri, Kentucky and Kansas. Governors of Kentucky, West Virginia and Illinois declared emergencies or disasters in several counties.
