High water levels are still posing a threat in South Carolina, and the situation is expected to worsen as rivers continue to rise, according to catastrophe modeling firm AIR Worldwide. Additional rain is expected to affect some areas over the weekend.

The floodwaters continue to rise due to excess runoff as the saturated ground cannot absorb more water. The ground had already been saturated from previous storms that affected the area in September, which prevented much of the water from the October rains from being absorbed into the ground.

Several dams have failed affecting water supplies and worsening the flood threat to several communities. One dam was breached intentionally to alleviate pressure. Similar to many earthen dams and levees in the United States, some of these dams are susceptible to weakening from rainfall.
