Part of the 2024 Atlantic hurricane season

Hurricane Isaac was a short-lived tropical cyclone, the ninth named storm and sixth hurricane of the 2024 Atlantic hurricane season. Isaac developed from a non-tropical low over the Atlantic, becoming Tropical Storm Isaac on September 26. It rapidly intensified throughout the day and became a hurricane on September 27, 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. By September 29, Isaac had weakened back down to a Tropical Storm. On the morning of September 30, Isaac had transitioned into a post-tropical cyclone.

In preparations for the possible affects of Isaac, the Portuguese Institute of Sea and Atmosphere (IPMA) put the Azores under a Yellow warning.

On September 25, a non tropical disturbance was noted by the National Hurricane Center with low chances to form.[1] Throughout the day, the showers and thunderstorms associated with the low consolidated. The area of low-pressure then detached from a frontal boundary a few hours later, and was designated Invest 99L.[2] The chances for development into a tropical cyclone went up, and early on September 26, Invest 99L was named Tropical Storm Isaac.[3] Throughout the day, Isaac Strengthened some more, and by noon that same day.[4] It continued to strengthen throughout the day, and early on September 27, it became a Category 1 hurricane.[5] Isaac continued to strengthen, and became a high end Category 1 hurricane.[6] Overnight, it continued to rapidly intensify to reach peak intensity early the same day, with a peak of 105mph, and a pressure of 968 millibars.[7] After reaching Peak Intensity, Isaac's intensification leveled off.[8] Late on September 28, Isaac started to began weakening, and the eye started to fill back up with clouds.[9] Early overnight on September 29, Isaac had rapidly weakened back to a Category 1 hurricane.[10] By Mid - day on September 29, Isaac was a minimal hurricane with 75 mph winds.[11] By nighttime on September 29, Isaac had weakened to a tropical storm.[12] Isaac Continued weakening on September 30. Around mid - day on September 30, Isaac was a post-tropical cyclone, and the NHC stopped its advisories.[13]
