Isaac is forecast to move into the eastern Caribbean Sea on Thursday, and then move across the eastern and central Caribbean Sea through Saturday, the hurricane center said.

At the moment there is intense cyclonic activity, consisting of a Category 2 hurricane (Florence), three tropical storms (Isaac, Joyce and Helene) and a disturbance in the Gulf of Mexico that is likely to become a tropical depression in the coming hours.

Although Olivia is expected to move over the islands as a tropical storm, it could still bring worse impacts than recent Hurricane Lane to some areas, the center said. "The recent flare-up in activity is associated with an enhanced west African monsoon system, which has been helping to fuel the development of storms over the far eastern Atlantic".

In a briefing today (Friday, September 14), the national meteorological office said that current guidance indicates that Helene will take a northeastward track towards Irish shores in the early days of next week.

No coastal watches or warnings were in effect as of Monday morning.

The NHC also says that Helene is expected to produce total rainfall amounts of two to four inches across the Azores, with isolated amounts up to eight inches across the western Azores.

However, experts remained unsure midday Wednesday where the storm would make landfall in the Carolinas.
