Through the end of the workweek, a low-pressure system is predicted to bring heavy rain and possibly flash floods to the Southeast coast, which includes Georgia, South Carolina, and North Carolina.
Forecasters decided Wednesday morning that there was no longer any likelihood of the system developing any tropical characteristics, but the National Hurricane Center (NHC) had been keeping an eye on it for possible tropical development this week.
After dumping over 6 inches of rain over South Florida, including Miami, between Monday and Tuesday, the region of low pressure will start to travel up the Southeast coastline on Wednesday afternoon.
The window for any potential tropical development is already closed as forecasters predict that this storm system will track over land.
“It is becoming increasingly likely that this development will occur inland over South Carolina and North Carolina,” the NHC stated in its Wednesday morning outlook. “As a result, the low’s chances of acquiring subtropical or tropical characteristics have diminished.”
Strong wind shear across the possible development area and a sizable pocket of dry air on the system’s backside also kept it from developing any tropical traits.
Forecasters are urging coastal residents to stay vigilant even though there are no longer any opportunities for tropical development.

On Wednesday afternoon, rain will start to fall along the coastlines of Georgia and South Carolina. On Wednesday evening and into Thursday early, it will move to the coast of North Carolina.
Through Friday, the Charleston, South Carolina, and Wilmington, North Carolina, metro regions are predicted to receive at least 3 inches of rain, with localized rainfall totals of up to 5 inches possible.
The most intense rain seems to be offshore for the time being.
On Wednesday, Florida, Georgia, South Carolina, and North Carolina were all under a Level 1 out of 4 flash flood hazard, according to NOAA’s Weather Prediction Center.
A large portion of the South Carolina coast, including Charleston, is at risk of flash floods, with a Level 2 out of 4 rating.
