Rain, rain and more rain is the foremost concern for the Lowcountry as Tropical Storm Chantal is forecasted to hit the eastern coast just in time for the weekend.

The storm system, which is currently working its way past Haiti, showed signs of weakening overnight. But thunderstorms are still building in the Bahamas as the storm drudges through the Caribbean in what National Weather Service meteorologist Richard Thacker called a ragged fashion.

“It’s going to be a sloppy track with this one,” Thacker said. “Confidence is pretty low in terms of this system developing a pronounced tropical center.”

Chantal will likely continue to weaken into a depression before it reaches the United States, Thacker said.

Thunderstorms are still a threat locally not only because of Chantal, but also due to a cold front that is expected to come down on Friday.

That means the Lowcountry should be on the lookout for potential flooding, Thacker said.

“We’re going to see storms from this cold front and then moisture from the Chantal. We’re going to see just all kinds of increasing coverage of rain over the weekend,” Thacker said.

It’s too early to tell where exactly Chantal will hit along the coast. The storm’s strength could change at any moment, Thacker said.

“We need to continue to keep an eye on it. These storms can be fickle. They can strengthen and weaken unexpectedly,” Thacker said.
