Both have a 30% chance of development within the next five days. For the one in the central Atlantic, the hurricane center said that “some gradual development of this system is possible during the next several days while it moves westward at about 15 mph toward the eastern Caribbean islands.”
For the other one, in the eastern Atlantic near the Cabo Verde Islands, “some development of this system is possible early next week when it begins to move slowly westward over the eastern and central tropical Atlantic,” according to the hurricane center.
Should the systems develop into named storms, the next two names on the list are Nana and Omar. Storms get names when their sustained winds reach 39 mph.
