Issued at 800 PM MST Fri Sep 13 2024 750 WTPZ44 KNHC 140236 TCDEP4 Tropical Storm Ileana Discussion Number 7 NWS National Hurricane Center Miami FL EP092024 800 PM MST Fri Sep 13 2024 Tropical Storm Ileana is gradually becoming less organized as it skirts the southern coast of Baja California Sur. Infrared satellite imagery shows convection being stripped away from the low-level circulation and radar imagery from Cabo San Lucas still shows a poorly organized, elongated center. Based on the degraded presentation of the storm and the earlier ASCAT data, the initial intensity is set to 35 kt for this advisory. The storm is moving northward at 8 kt, and the center is expected to begin pulling away from the coast of Baja California Sur in the next couple of hours. This motion should continue through most of Saturday before the weakening cyclone turns more north-northwestward over the Gulf of California. The track guidance has shifted eastwards slightly, largely due to the initial position, and new NHC track forecast lies between the consensus aids and the previous prediction. Vertical wind shear is expected to increase dramatically over Ileana in the next day or so. The model guidance is in good agreement that weakening should continue, and the official intensity forecast now shows Ileana becoming a depression by Saturday, a remnant low by Sunday, and dissipated by early next week. However, it is possible this could occur sooner. Key Messages: 1. Tropical Storm Ileana will bring heavy rainfall to portions of western Mexico and southern Baja California Sur through this weekend. This heavy rainfall will bring a risk of flash flooding and mudslides to portions of the area. 2. Tropical storm conditions could continue in portions of Baja California Sur during the next several hours where Tropical Storm Warnings are in effect.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 24 hours. Interests elsewhere in the Mexican states of Baja California Sur, Sinaloa, and Sonora should closely monitor the progress of Ileana. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 PM MST (0300 UTC), the center of Tropical Storm Ileana was located near latitude 23.5 North, longitude 109.3 West. Ileana is moving toward the north near 9 mph (15 km/h). A steady northward to north-northwestward motion is expected during the next few days. On the forecast track, Ileana is forecast to move near or over the southern portion of the Baja California peninsula this evening, and over the southern and central Gulf of California this weekend. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual weakening is forecast during the next couple of days, and Ileana is expected to weaken to a tropical depression on Saturday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Ileana can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4 and WMO header WTPZ44 KNHC. RAINFALL: Through this weekend, Tropical Storm Ileana may produce rainfall of 4 to 6 inches, with localized higher amounts up to 8 inches, across southern Baja California Sur. For northwest coastal Sinaloa, Tropical Storm Ileana may result in between 6 to 8 inches with localized higher amounts up to 12 inches. For a complete depiction of forecast rainfall associated with Tropical Storm Ileana, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep4.shtml?rainqpf WIND: Tropical storm conditions are expected across portions of the warning area in the southern Baja California Peninsula through this evening and into early Saturday. Tropical storm conditions are possible within the watch area by early Saturday. SURF: Swells generated by Ileana will affect portions of the coast of west-central Mexico and the coast of the southern Baja California Peninsula during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Issued at 200 PM MST Fri Sep 13 2024 000 WTPZ44 KNHC 132041 TCDEP4 Tropical Storm Ileana Discussion Number 6 NWS National Hurricane Center Miami FL EP092024 200 PM MST Fri Sep 13 2024 Satellite imagery and radar data from Cabo San Lucas indicate that Ileana remains poorly organized with poorly-defined convective banding around the elongated center. The latest satellite and radar imagery suggests the center is just east of the latest burst of convection south of Cabo San Lucas, and this is in reasonable agreement with positions from recently received ASCAT data. The scatterometer passes show 30-35 kt winds to the east of the center, and based on this and the possibility of undersampling, the initial intensity is held at a possibly generous 40 kt. The scatterometer and and an earlier microwave image show that Ileana is moving slower than thought previously, and the initial motion is now 345/6. A slow north-northwestward to northward motion should continue until the cyclone dissipates, with the center passing near or over the southern end of the Baja California peninsula during the next 6-12 h and then moving over the central and southern Gulf of California. The track guidance shifted a little to the east of the previous guidance, and the new forecast track is a little to the east of the previous track. The cyclone should be moving into an environment of increasing southwesterly to westerly shear and a drier airmass as it moves into the Gulf of California. The intensity guidance is in good agreement that Ileana should weaken, and the new intensity forecast follows this trend. The forecast now calls for the system to become a depression by 36 h, a remnant low by 48 h, and dissipate by 72 h. It is possible that Ileana could decay to a remnant low by 36 h, as the GFS and ECMWF forecast the associated convection to dissipate by that time. Key Messages: 1. Tropical Storm Ileana will bring heavy rainfall to portions of western Mexico and southern Baja California through this weekend. This heavy rainfall will bring a risk of flash flooding and mudslides to portions of the area. 2. Tropical storm conditions are expected to begin in portions of Baja California Sur during the next several hours where Tropical Storm Warnings are in effect.
