Unsettled weather for SC; low chance for tropical development

Lots of moisture is available for rains across eastern South Carolina.

The National Hurricane Center has labeled an area over northern Florida, which extends through the northwestern Gulf, with a 20% chance of tropical development through the next seven days.

In the short term, there’s no chance for development; in fact, there’s no system there as of Saturday evening. As the week progresses, we’re going to be monitoring a weak low-pressure system that will develop over the southeastern United States. This disturbance should move off the coast of the Carolinas between Monday and Tuesday. As the Bermuda High strengthens and moves west, this low-pressure system will be pushed west, likely over Florida.

Once over the Gulf, the low-pressure system should begin to acquire a cluster of thunderstorms and perhaps a counterclockwise rotation. If a tropical storm forms, it will likely develop slowly, and we will continue to provide updates throughout the workweek. Please stay tuned for the release of our forecast throughout the week.

There is a marginal chance for flash floods on Monday across the northern Midlands and Pee Dee.

With an approaching cold front as well as the low pressure near North Florida, there will be plenty of instability nearby. There will be periods of heavy rains on Monday and Tuesday, especially across the northern Midlands and the Pee Dee, where there are between 2 and 4 inches of rain that could fall through late Tuesday morning. Higher isolated amounts are possible. Please stay away from areas where flooding is happening or is prone to happen.
