Hurricane forecasters were eyeing two developing tropical systems in the Atlantic Ocean Aug. 10 – one of which could pose an eventual risk to the United States – while Tropical Storms Henriette and Ivo spin far from land in the Pacific Ocean.
In the central Atlantic, the National Hurricane Center said a tropical wave had a 20% chance of formation within the next seven days. "Development of this system should be slow to occur during the next couple of days due to surrounding dry air, but some gradual development is possible during the middle part of this week while the system moves northward over the central Atlantic," the hurricane center said.
Most computer models show this system heading north in the Atlantic, away from any land areas, as seen with the yellow x in the map below.
Of more potential concern to the United States, the hurricane center was also watching a separate tropical wave in the eastern Atlantic Ocean, dubbed Invest 97L. Officials gave that an 80% chance of forming within the next seven days. (Looking for the location? It's the red x in the map above.)
"This is by far the healthiest looking tropical wave we've seen off Africa this summer," said Houston-based meteorologist Matt Lanza on Aug. 10 in a Substack post.
