A slow-moving storm system, rich in moisture, has deposited up to half a foot of rain from South Carolina to Tennessee, leading to significant flooding issues.

Through midday Monday, Weather.com reported the rains had “already forced water rescues, knocked out power to thousands and triggered significant flooding of multiple streets.”

Due to the deluge, the National Weather Service had issued flood warnings and advisories in the Carolinas, northeastern Tennessee, and western Virginia.

Because the storm system was largely cut off from the main atmospheric flow, it was moving at a snail’s pace, allowing rainfall amounts to pile up.

The heaviest rainfall was focused over northeast South Carolina and southeast North Carolina where the Weather Service declared a moderate risk of excessive rainfall. “[We] would anticipate some isolated six to ten inches totals in this vicinity,” the Weather Service said.

Some of the hardest-hit areas in southeast North Carolina also endured significant flooding from Hurricane Matthew in the fall.
