Along with Hurricane Gabrielle, which is currently tracking east of Bermuda, the National Hurricane Center is monitoring two tropical disturbances in the central Atlantic for potential development this week. The National Hurricane Center says a tropical depression is likely to form by mid to late week as the system moves west-northwestward. A tropical depression could form late this week as the system moves into the southwestern Atlantic Ocean, according to the National Hurricane Center. While the climatological peak of the Atlantic hurricane season has passed, roughly 60% of tropical activity typically occurs after Sept. 10, on average, according to the National Hurricane Center. Last year demonstrated that late September and early October can be an active period for tropical development, with multiple threats that may be high-impact and potentially devastating.
