At first, computer models forecasted the low-level circulation to turn southwestward and re-emerge into the Gulf of Mexico. However, the storm rapidly weakened over land, and by 1200 UTC on September 24 Ivan degenerated into a remnant low pressure area over southeastern Texas. The low turned to the south and the circulation dissipated early on September 25. The remnant trough reached the northwestern Gulf of Mexico later that day, producing scatter thunderstorms for a short time, before it diminished.
