Multiple Tropical Disturbances Tracked in the Atlantic, Potential Impact on North America Unclear

Two disturbances in the Atlantic Ocean have merged to form an elongated low, with a high chance of becoming a tropical depression over the next seven days, according to the National Hurricane Center (NHC). The system, previously identified as Invest 97L and Invest 98L, now has a 70% chance of developing into a tropical depression by the weekend. The NHC expects gradual development as the system moves west-northwestward or northwestward across the central tropical Atlantic. If it becomes a tropical storm, it will be named Nigel.
