Floodwaters continue to rise on portions of Carolina rivers even a full week after Florence’s arrival

While crests will continue to work downstream along the major rivers in the eastern part of the Carolinas into next week, some unprotected areas may stay flooded until the end of September or early October.

It has taken this long for runoff from the torrential rain that fell on the Carolina Midlands to reach the coast. Since many of the rivers near the coast are slow moving, meandering and tidal in nature, conditions will be worse at times of high tide this weekend.

Portions of rivers near the coast that may take until early next week to crest include the Waccamaw and lower Neuse.

As the waters recede, the scope of the damage will be revealed. However, it may take many days and weeks for loss of life and the full scope of the damage to be accessed.

Because of the high levels of water on the rivers, regardless of recent, current or near-future crest, it may take many additional days for officials to declare roads that were under water for days to be safe.

Support under area roads and bridges may have been weakened, undermined or washed away.

People should not attempt to drive around barriers that have been in place for this reason, even though the road in that vicinity may appear to be in good shape.

Some of the rivers near the coast may remain out of their banks until early October, which means that some farmland and small communities may be inundated for two weeks or more after the initial flood.
