Hurricane forecasters are watching Isaac, Joyce and perhaps Kirk

As Helene swept across Florida and dumped rain across the Southeast, hurricane forecasters were monitoring three systems in the Atlantic.

One of them is a new hurricane far out in the ocean. Hurricane Isaac formed nearly 1,000 miles (1,600 kilometers) from Bermuda on Friday morning, the National Hurricane Center said.

It is the sixth hurricane of the 2024 Atlantic hurricane season, but for people in the United States it may be the least worrisome.

Meanwhile, meteorologists were also monitoring the Caribbean Sea, where another system appears to be brewing in a location similar to where Hurricane Helene formed. Here's what you should know.

Tropical Storm Joyce also formed on Friday

Elsewhere, meteorologists were tracking newly formed Tropical Storm Joyce, which is located in the central Atlantic about 1,325 miles east of the Northern Leeward Islands in the Caribbean. Joyce is moving northwest at about 13 miles per hour, and that general motion is expected to continue through Sunday at a gradually slowing forward speed, the hurricane center said. A gradual turn to the north is forecast for Monday.
