Florence, a potentially life-threatening Category 4 hurricane, is on track to make landfall in North Carolina or SC on Thursday (Sept. 13).

Isaac was a hurricane Sunday night but downgraded when maximum sustained winds fell below 74 miles per hour.

Isaac is forecast to move across the central Lesser Antilles and into the eastern Caribbean Sea Thursday, and then move across the eastern and central Caribbean Sea through Saturday.

After forecast models showed steering currents collapsing as the storm nears the Carolina coast Tuesday, forecasters shifted the track slightly south.

Emma Smith of the Met Office added: "Helene is moving up from the Atlantic towards us".

Winds of up to 80mph are forecast to hit Dumfries and Galloway from Monday night when the United Kingdom is battered by Storm Helene. As of Wednesday afternoon, Helene had maximum sustained winds near 90 miles per hour.

Road and bridges may close, with fallen trees are expected.

The NHC said, "A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 24 to 36 hours".

The storm is moving at 17 miles per hour to the west and has 60 miles per hour winds.

"The rain's going to be around for a long time", he said.

Behind Isaac, Hurricane Helene also continued to deliver good news.

A system in the central Gulf of Mexico was a little less certain. While early on Wednesday the odds of it forming dropped, by afternoon forecasters had again increased the chance to 70 percent over two days. Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana late this week. A hurricane hunter plane is scheduled to investigate the system Thursday.

While now classified as a hurricane, Helene will be downgraded to a storm by the time it reaches the shores of Northern Ireland.
