Tropical Storm Lee is expected to intensify into an extremely dangerous category four hurricane by the weekend.
The storm has formed over the Atlantic and is likely to reach hurricane status later Wednesday, the US National Hurricane Center (NHC) said.
It said it was too early to determine its potential impact or whether it would reach land in the United States.
“Lee is forecast to become a major hurricane… and could bring impacts to the Leeward Islands,” the NHC said.
“While it is too early to determine the location and magnitude of these potential impacts, interests in this area should monitor Lee’s progress,” it said.
Lee’s winds are predicted to reach 145 mph (233 km/h) later in the week, which would place it as a category four hurricane.
The NHC describes this category as “major” and says that if a hurricane of this scale were to make landfall, “catastrophic damage will occur”.
It comes just days after Hurricane Idalia made landfall in Florida, where it destroyed homes and downed power lines before barreling into Georgia and bringing severe weather to the Carolinas. Major power outages lasted for days in Georgia, with more than 200,000 people affected.
Mid-September is considered to be the peak of the hurricane season, which ends on 30 November.
The 2023 Atlantic hurricane season is forecast to be more active than average, with the peak of the season still a week away.
The effect of climate change on the frequency of tropical storms is still unclear, but increased sea surface temperatures warm the air above and provide more energy to drive hurricanes.
As a result, they are likely to be more intense with more extreme rainfall.
