Disturbance Off Of South Carolina Coast Has Narrow Window For Development The Next 24 Hours

As of 8pm EDT Sunday evening, a loosely organized area of showers and storms was located about 425 miles ESE of Charleston, SC. At times on Sunday it has shown signs of getting better organized, but strong upper-level winds have been working against so far Sunday evening.

It is moving fairly quickly to the northwest at 15-20 mph. This leaves only about 24 hours until it comes ashore along the GA/SC coast. What could provide a bit of a boost, and elevate this to a tropical depression or weak tropical storm between now and then, is the energy that will be provided as it moves over the warm waters of the Gulf Stream. For now, the National Hurricane Center has put development odds at 50%.

Regardless of development, localized 1-3″ rainfall totals will be possible along the immediate coasts of Georgia and South Carolina through Monday night.

A Couple Areas Of Interest In The Atlantic; No Immediate Concerns

Claudette moved through the Southeast about a week ago, and things have been fairly quiet since then. That being said, we are keeping an eye on a couple areas in the Atlantic. As it stands right now, neither of these look like they’re going to be a threat.

First, we have a disturbance located a couple hundred miles south of Bermuda that will be moving toward Georgia and the Carolinas over the weekend. While some slow development is possible, this will most likely just assist in bumping up rain chances for parts of the southeastern U.S. Atlantic coast early next week.

We’ve also been keeping tabs on a robust tropical wave in the far eastern Atlantic. While this has shown signs of better organization at times over the last few days, it will be moving into a large area of dry air and Saharan dust in the coming days that will make any significant development very difficult.
