An Air Force Reserve Hurricane Hunter aircraft was en route to investigate the storm and provide more data.

Even if it doesn't become Chantal, the system is expected to bring stormy weather to areas from Florida to the Carolinas, according to Weather dot com.

The National Weather Service in Jacksonville, Florida, warned of slick roads, heavy downpours, and possible flooding in low-lying areas.

Michael Lowry, a hurricane specialist at WPLG 10 in Miami, said heavy rainfall will be the biggest risk along the Georgia and Carolina coasts this weekend.
Lowry said the storm is expected to pick up speed by Tuesday or Wednesday and move northward along the Eastern Seaboard. After that, forecasters say the Atlantic should remain quiet for the rest of the week.

If it is named, Chantal would follow Tropical Storms Andrea and Barry earlier this year.
