Part of the 2024 Atlantic hurricane season

Hurricane Isaac was a short-lived hurricane in the open Atlantic. The ninth named storm and sixth hurricane of the 2024 Atlantic hurricane season, Isaac slowly developed from a non-tropical low over the Atlantic.[1] As showers and thunderstorms associated with the low consolidated,[2] the low detached from a frontal boundary a few hours later.[3]Despite having low chances for development originally, it quickly intensified into Tropical Storm Isaac early on September 26.[4] It intensified throughout the day and became a hurricane on September 27.[5] Soon after becoming a Category 1 hurricane, Isaac underwent an eyewall replacement cycle and intensified into a Category 2 hurricane later that same day. Early on September 28, Isaac would reach peak Intensity at 105 mph and a pressure of 968 millibars. [6] After undergoing rapid intensification to reach peak intensity, The intensification had leveled off. [7] On September 29, Isaac had began weakening and by late that day, had weakened back down to a tropical storm. The weakening was mainly due to increases in unfavorable sea surface temperatures, wind shear, and dry air.[8] On the morning of September 30, Isaac had transitioned into a post-tropical cyclone. In preparations for Isaac, the Portuguese institute of sea and Atomsphere (IPMA) put the Azores under a Yellow warning. [9]
