"Currently Helene is 2000km southwest of the Azores and remains a category 1 hurricane, with sustained winds of 130kph and gusts in excess of 170 kph".
Florence, a potentially life-threatening Category 4 hurricane, is on track to make landfall in North Carolina or SC on Thursday (Sept. 13).
"Isaac has become less organized and is now a weak Tropical Storm".
If these projections hold, University of Miami hurricane researcher Brian McNoldy says "it's exceptionally bad news, as it smears a landfall out over hundreds of miles of coastline, most notably the storm surge".
All eyes are on Hurricane Florence and its path toward the Carolinas, but other hurricanes and tropical storms are brewing as well.
The Met Office assured that Tropical Storm Isaac poses no direct threat to Trinidad and Tobago as it continues to move away from the Lesser Antilles. This rainfall may cause unsafe flash flooding, N.H.C. said.More news: Met Office 'danger to life' warning as winds to hit Northern Ireland
The storm is moving at 17 miles per hour to the west and has 60 miles per hour winds. And the timing couldn't be more apt: Monday was the peak of the Atlantic hurricane season, when storm activity has historically been at its highest.
Up to 1.7 million people have been ordered to evacuate across South Carolina, North Carolina and Virginia.
Some fluctuation in wind speeds are expected, and weakening forecast Thursday, but it's still expected to be a fierce storm triggering unsafe flooding.
The center of the Category 4 Hurricane, still swirling with top winds of 130 mph (215 kph), was about 530 miles (855 kilometers) southeast of Cape Fear, North Carolina, approaching the coast at 17 mph (28 kph). Swells generated by the storm could produce life-threatening surf and rip current conditions.
Water could reach as high as 4 feet from Edisto Beach to the South Santee River.
"There are no coastal watches or warnings in effect", said the NHC in its 11 a.m. September 12 update. However, the center of Florence could hit as early as Thursday night rather than Friday morning, according to the latest NOAA estimates at the time of this writing.
