If the system develops into a tropical storm or hurricane, it could bring heavy rainfall to parts of the Gulf Coast, particularly Florida. Even if it does not reach tropical storm status, the region is expected to experience significant rainfall. Historically, storms named Isaias have caused notable impacts, such as flooding in the Philadelphia area in 2020. The quiet season so far has been attributed to El Niño conditions, which increase vertical wind shear and disrupt storm formation. However, this system could break the record for the latest first hurricane in a season if it forms after October 8.
