Interests elsewhere in the Baja California peninsula should monitor the progress of Priscilla. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 PM MST (2100 UTC), the center of Hurricane Priscilla was located near latitude 18.3 North, longitude 108.0 West. Priscilla is moving toward the north-northwest near 7 mph (11 km/h). A turn toward the northwest at a slightly faster forward speed is expected over the next few days. On the forecast track, the center of the system is expected to move offshore of and parallel to the coast of west-central Mexico and Baja California Sur through the middle part of this week. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Strengthening is expected over the next day or two, and Priscilla is forecast to become a category 2 hurricane before weakening begins by midweek. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 972 mb (28.71 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Priscilla can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP1 and WMO header WTPZ41 KNHC. WIND: Tropical storm conditions are possible within the watch area along the west-central coast of Mexico through today, and are possible in Baja California Sur Tuesday night into Wednesday. RAINFALL: Outer bands from Priscilla will continue to bring heavy rain to portions of west-central Mexico today. Across coastal portions of Michoacán and Colima, additional rainfall amounts of 1 to 2 inches are expected. From Tuesday into Wednesday, 1 to 2 inches with local storm total amounts to 4 inches are expected in southern portions of Baja California Sur due to the outer bands of Priscilla. This rainfall could bring a risk of flash flooding, especially in areas of higher terrain. Moisture from Priscilla should bring heavy rainfall potential over the Southwest U.S. late this week into this weekend. For a complete depiction of forecast rainfall and flash flooding associated with Priscilla, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep1.shtml?rainqpf SURF: Swells generated by Priscilla are affecting portions of the coast of southwestern and west-central Mexico, as well as portions of the coast of the southern Baja California peninsula. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 500 PM MST. Next complete advisory at 800 PM MST.

Expires:No;;227631 WTPZ41 KNHC 062041 TCDEP1 Hurricane Priscilla Discussion Number 9 NWS National Hurricane Center Miami FL EP162025 200 PM MST Mon Oct 06 2025 Priscilla has a very large area of banded convection that spirals into a central area that has shown signs of some clearing from time-to-time. Satellite intensity estimates haven’t changed much from the previous advisory. A recent ASCAT pass from 06/1604 UTC shows that the system still has a large radius of maximum winds (RMW). The strongest vectors of 50-55 kt were mainly located in the eastern semicircle. It’s possible that slightly stronger winds could be located just outside the edge of the scatterometer pass. The initial intensity is maintained at 75 kt, but this could be a bit generous. Priscilla is moving a bit faster toward the north-northwest, or 340 degrees at 6 kt. A more northwestward track with some slight additional acceleration is expected by this evening as mid-level ridging becomes better established over Mexico. The model guidance has come into slightly better agreement through 72 hours. Beyond 72 hours, a turn toward the north is expected as a trough just off the coast of California picks up the cyclone. The latest NHC forecast has been adjusted slightly to the right of the previous forecast, and is a bit faster at day 4 and 5. The new NHC track lies slightly to the left of the HFIP Corrected Consensus (HCCA) and Google DeepMind Ensemble Mean. The inner core and RMW of Priscilla has not contracted yet, and the hurricane has also not strengthened over the past 12 hours. Moderate vertical wind shear and some sneaky dry slots noted on water vapor imagery could be preventing Priscilla from developing a tight inner core. Until that happens, only slow strengthening is anticipated. The NHC intensity forecast is similar to, but slightly lower than the previous forecast, and lies near the middle of the guidance envelope. Priscilla is forecast reach colder waters, and the system is forecast to weaken below hurricane strength shortly after that time. Priscilla is likely to lose its deep convection and become a remnant low just beyond 96 h. The weakening circulation could reach the northern Baja California peninsula just before it dissipates. Enhanced moisture is likely to make its way toward portions of the southwestern United States. KEY MESSAGES: 1. Tropical storm conditions are possible along portions of the coast of west-central Mexico through today, and in Baja California Sur Tuesday night into Wednesday, within the watch areas. Interests elsewhere in the Baja California peninsula should monitor the progress of Priscilla. 2. Heavy rainfall associated with Priscilla will impact portions of southern Baja California Sur, which could result in flash flooding, particularly in areas of higher terrain. 3. Swells generated by Priscilla are affecting portions of the coast of southwestern and west-central Mexico as well as the coast of the southern Baja California peninsula. These swells are likely to cause life-threatening surf and rip current conditions.
