227 WTPZ44 KNHC 151440 TCDEP4 Post-Tropical Cyclone Ileana Discussion Number 13 NWS National Hurricane Center Miami FL EP092024 800 AM MST Sun Sep 15 2024 Ileana has been devoid of deep convection since yesterday afternoon, as the system has been within a strong wind shear and very dry environment. Given the lack of convection, the system is being designated as a post-tropical remnant low. An ASCAT-C pass from late last night depicted winds near 30 kt over the Gulf of California near northern Sinaloa. Given this, will hold the intensity at 30 kt for this advisory, although that may be generous. The system has been meandering over the Gulf of California with a motion of 310/3 kt. The remnant low will increase forward speed later today as it continues northwestward. The remnant low will continue to weaken throughout the day, and is forecast to dissipate on Monday. This is the last advisory on this system.
