Sara weakened after hitting Central America with overwhelming rains and flooding. The storm's remnants could soak the Southeast.

What was once Tropical Storm Sara continues to weaken and was downgraded to a tropical depression on Sunday afternoon after the deadly, late-season storm slammed portions of Central America with torrential rain that led to catastrophic flooding and mudslides.

As of the 4 p.m. advisory, Sara was a weakening tropical depression straddling the area between Mexico and Guatemala, according to the National Hurricane Center. The system is expected to move into the Gulf of Mexico in the next day but will dissipate at that point.
