The ocean is currently home to three giant storms.
But whereas Hurricane Florence, which is set to batter the east coast of the United States today, and Tropical Storm Isaac, likely to make landfall on the Dominion Republic at roughly the same time, are posing problems across the pond, Helene is threatening chaos in Britain.
The latest NHC map shows Helene moving in an easterly direction across the north Atlantic as of 10am BST (5am AST) today, packing winds of up to 100 miles per hour.
An accompanying NHC advisory suggested a turn toward the north-northeast with an increase in forward speed was expected tonight.
This is likely to be followed by a turn toward the northeast over the weekend.
If it maintains that course, it could make landfall on the south coast of Ireland and west coast of the UK at 1pm BST (8am AST) Monday morning.
Met Office meteorologist Alan Deakin said: “Hurricane Helene may influence things in combination with an area of low pressure over the coming days.
“Areas of low pressure containing what’s left of Storm Helene will still provide moisture and energy which will impact the UK quite a bit as we go into the early part of next week.
“There is a lot of uncertainty around the development of that low pressure system.”
The severe-weather.eu website warned: “While many are focusing on the dangerous major hurricane Florence, there is another interesting and potentially dangerous tropical system in the Atlantic.
“The Category 1 hurricane Helene is heading towards Europe early next week.
“Helene is currently still in the central Atlantic, but is moving towards the Azores.
“Later on, Helene will become a post-tropical storm and accelerates towards western Europe.
“It is possible the ex-hurricane Helene will be pushed into British Isles and Ireland on Monday and bring gale force winds and torrential rainfall into the region.”
Although Helene is currently classified as a hurricane, continued weakening is forecast over the next couple of days.
It may be downgraded to a tropical storm tonight.
With three major weather systems in the Atlantic, the ocean’s hurricane season is now well and truly underway, having officially started on June 1.
This year has seen Tropical Storms Alberto, Debby, Ernesto, Joyce and Gordon, plus five which classified as hurricanes.
Of these Florence, currently rated as a category 4 storm, is easily the most powerful.
Several more hurricanes are likely before the season officially ends on November 30.
