Issued at 500 PM HST Wed Sep 03 2025 022 WTPZ41 KNHC 040253 TCDEP1 Hurricane Kiko Discussion Number 16 NWS National Hurricane Center Miami FL EP112025 500 PM HST Wed Sep 03 2025 Kiko remains a powerful category 4 hurricane, with satellite images showing a well-defined eye surrounded by a very cold ring of deep convection with cloud top temperatures of -70 to -85C. The most recent subjective Dvorak current intensity estimates from TAFB and SAB were 6.0/115 kt and 6.5/127 kt respectively, while the objective estimates from UW-CIMSS have ranged between 119 and 132 kt during the past several hours. Based on a blend of these data, the initial intensity has been raised to 125 kt for this advisory. Kiko is moving just south of due west, or 265 degrees, at 8 kt. This general westward motion is expected to continue through Thursday night, as the cyclone is steered by a building subtropical ridge to its north and northwest. A turn toward the west-northwest is forecast on Friday as an upper-level trough north of Hawaii begins to erode the western portion of the subtropical ridge, with this general motion then continuing through the weekend with a gradual increase in forward speed. There remains some along-track and cross track spread among the global models, although the spread has decreased considerably during the past 24 hours. The official track forecast remains in good agreement with a blend of the latest multi-model consensus aids and is nearly on top of, but slightly slower than, the previous forecast track. Kiko will remain over warm waters of 27–28C and influenced by mostly light vertical wind shear through around 60 to 72 hours. The surrounding environmental mid-level moisture will remain drier than optimal, hovering between 50 and 60 percent during the next couple of days, before dropping below 50 percent by day 3. Despite the somewhat dry mid-level airmass, the light vertical wind shear and warm sea surface temperatures should maintain Kiko as a major hurricane through day 3. There will likely be some fluctuations in strength during the next several days with the potential for eyewall replacement cycles during this time. By days 4 and 5, the cyclone will begin moving over cooler water with gradually increasing westerly vertical wind shear, and mid-level moisture plummeting below 40 percent. These factors should lead to steady and eventually rapid weakening of Kiko as the cyclone approaches the Hawaiian Islands from the east. Kiko will be influenced by environmental factors that can lead to the development of annular characteristics along its approach, which can slow the rate of weakening. As a result, the official intensity forecast remains on the higher end or slightly above the intensity aids through day 5, and is very close to the previous advisory.

Issued at 800 PM MST Wed Sep 03 2025 189 WTPZ42 KNHC 040251 TCDEP2 Hurricane Lorena Discussion Number 9 NWS National Hurricane Center Miami FL EP122025 800 PM MST Wed Sep 03 2025 Objective satellite intensity estimates from UW-CIMSS (ADT, AiDT, and SATCON) have increased by 5 to 10 kt since the Air Force Reserve reconnaissance mission into Lorena earlier this afternoon. Since the plane's data suggested an intensity of 70 kt at that time, the current intensity is estimated to be about 75 kt. That said, Lorena is probably at its peak intensity. There are already signs in conventional and microwave satellite imagery that vertical shear is beginning to strengthen, with a sharpening of the southern side of the upper-level cloud pattern and some tilt of the circulation with height. The shear is forecast to gradually increase over the next couple of days, and Lorena will also be moving over waters colder than 26 degrees Celsius in about 6 to 12 hours. Therefore, quick weakening is shown in the official forecast. Lorena continues to move toward the northwest, or 310 degrees, but at a slightly slower 10 kt. As the cyclone moves farther into a break in the subtropical ridge, it is expected to turn northward and slow down further by Thursday evening, and then move only slowly north-northeastward into the weekend. The 18z GFS run is finally playing the same tune as much of the other guidance, showing Lorena quickly decoupling as the shear removes its deep convection and leaving the low-level center drifting toward the west coast of Baja California Sur. Now that there is near-unanimous agreement that Lorena is unlikely to move quickly as a deep system toward northwestern Mexico, the NHC track forecast has been slowed down significantly, blending the previous forecast with the most recent HCCA and TVCE consensus aids. This new forecast brings Lorena's center to the west coast of Baja California Sur in about 48 hours as a weakening tropical cyclone, with the system reaching the east coast of the peninsula as a remnant low in about 60 hours. However, based on the latest GFS- and ECMWF-based simulated satellite imagery, the transition to a remnant low could occur earlier than that. Even if Lorena weakens and becomes a remnant low earlier than previously predicted, abundant moisture will continue to stream northeastward away from the cyclone. Because of that, there is still a significant risk of heavy rainfall and flash flooding across portions of Baja California Sur, Sonora, and southern Arizona and New Mexico. Key Messages: 1. Heavy rainfall associated with Lorena will continue to impact Baja California Sur and shift into southwestern Sonora Thursday. This will increase the risk of life-threatening flash floods and mudslides across northwest Mexico. 2. Moisture from Lorena will contribute to heavy rainfall concerns across Arizona and southwest New Mexico through Saturday. Isolated to scattered instances of flash flooding are possible across Arizona into Saturday. 3. The center of Lorena is forecast to move parallel to, but offshore of, the southwest coast of the Baja California Peninsula through Thursday, and then move closer to the west-central coast of the peninsula Thursday night and Friday. Regardless of the exact track, tropical storm conditions are likely along portions of the coast of Baja California Sur where a Tropical Storm Warning is in effect. Tropical storm conditions are also possible late Friday along the east coast of the Baja California peninsula, where a Tropical Storm Watch is in effect. 4. Life-threatening surf and rip current conditions will affect portions of the southern and western coasts of Baja California Sur during the next couple of days.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area within 48 hours. Interests elsewhere on the Baja California peninsula and in northwestern Mexico should monitor the progress of Lorena. Additional watches or warnings may be required tonight or on Thursday. 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 Hurricane Lorena was located near latitude 23.4 North, longitude 113.2 West. Lorena is moving toward the northwest near 12 mph (19 km/h), and this motion with a decrease in forward speed is expected through early Thursday. A slow northward or north-northeastward motion is expected to begin on Thursday and continue into the weekend. On the forecast track, the center of Lorena is expected to move parallel to the west coast of the Baja California peninsula through Thursday, approach the coast of Baja California Sur Thursday night, and move inland over the Baja California peninsula on Friday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Lorena is expected to begin weakening quickly and become a tropical storm on Thursday. Lorena is likely to degenerate into a remnant low near or over the Baja California peninsula by early Saturday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km). The estimated minimum central pressure is 981 mb (28.97 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lorena can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC. RAINFALL: Bands of heavy rainfall will continue to impact Baja California Sur and move into southwestern Sonora by Thursday, with this rainfall potentially persisting through Friday. Additional rainfall totals of 4 to 8 inches, with maximum storm total amounts of 15 inches, are possible across portions of Baja California Sur, far southeast Baja California and southwestern Sonora into Friday. This will bring the risk of life-threatening flash floods and mudslides, especially in areas of higher terrain. Farther northeast, 1 to 3 inches of rain, with localized totals up to 5 inches, are expected from portions of the Mexican state of Sinaloa north and northeast into portions of southeast Arizona and southwest New Mexico through Saturday, bringing the potential for isolated to scattered flash flooding. For a complete depiction of forecast rainfall and flash flooding associated with Hurricane Lorena, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep2.shtml?rainqpf WIND: Tropical storm conditions are expected in the warning area beginning tonight and will spread northward within the warning area in Baja California Sur through Thursday and into Friday. Tropical storm conditions are possible within the watch area south of Santa Fe for the next few hours, and in the watch area on the east coast of the Baja California peninsula late Friday into Friday night. STORM SURGE: Coastal flooding from storm surge is likely along the coast of Baja California Sur near and to the right of where Lorena makes landfall. SURF: Swells generated by Lorena will continue affecting portions of the south and west coasts of Baja California Sur through Friday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
