A trio of disturbances are lined up one after the other in the Atlantic Ocean, and at least two of them will probably develop in the coming days and become named tropical storms. While there is a large amount of uncertainty in the ultimate fate of all three disturbances, each of them has some potential to affect land areas from the Lesser Antilles to North America, depending on their exact tracks and whether they hold together and strengthen.
The parade of storms marks a sudden reawakening of the Atlantic basin that could kick hurricane season into overdrive in the coming weeks. The active stretch looks to carry into September, with multiple named storms probable through then.
The 2020 Atlantic hurricane season already has featured a typical season’s worth of named storms, with 11 having formed through mid-August, although none were overly intense. The factory-like storm production included the earliest C, E, F, G, H, I, J and K storms ever recorded in the Atlantic, part of a season that has been nearly twice as active as average.
Tropical Storms Kyle and Josephine, both short-lived, dissipated over the weekend, but Laura and Marco are up next and could be assigned to either of the two more robust tropical waves as they continue to churn west. The National Hurricane Center says both waves, labeled 97L and 98L, have 80 and 90 percent likelihoods, respectively, of becoming a tropical depression or storm over the next several days.
The active bout stems from a broad area of rising motion set to overspread the Atlantic and enhance tropical cyclone development. The same weather system brought a flurry of activity to the Pacific, transforming Genevieve, now just south of the Baja Peninsula, from a tropical storm to a Category 4 hurricane in less than 24 hours.
