Tropical Storm Karen Weakens on Approach to Gulf Coast

Winds at 40mph, may be downgraded

Tropical Storm Karen weakened Saturday as it approaches the central Gulf Coast, but forecasters are still expecting it to bring significant rain and potential flooding to low-lying areas.

Meteorologist David Bernard of CBS station WFOR in Miami reported on "CBS This Morning: Saturday" that, as of Saturday morning, Karen is a minimal tropical storm, with winds of 40 mph, and whether it even retains its status as a tropical storm remains to be seen.
