630 WTPZ33 KNHC 081437 TCPEP3 BULLETIN Post-Tropical Cyclone Marie Advisory Number 30 NWS National Hurricane Center Miami FL EP132026 800 AM PDT Tue Sep 08 2026 ...MARIE BECOMES A POST TROPICAL CYCLONE... ...THIS IS THE LAST ADVISORY... SUMMARY OF 800 AM PDT...1500 UTC...INFORMATION ---------------------------------------------- LOCATION...25.8N 127.4W ABOUT 770 MI...1240 KM W OF PUNTA EUGENIA MEXICO ABOUT 780 MI...1260 KM SW OF SAN DIEGO CALIFORNIA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 800 AM PDT (1500 UTC), the center of Post-Tropical Cyclone Marie was located near latitude 25.8 North, longitude 127.4 West. The post-tropical cyclone is moving toward the west-northwest near 9 mph (15 km/h) and is forecast to turn to the northwest over the next day or so. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Steady weakening is expected to continue, and Marie is forecast to dissipate in a couple of days. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Marie will continue to affect portions of the coast of the Baja California Peninsula and southern California for 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. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_ep3.shtml?ripCurrents NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.

Forecast Discussion — the forecaster's reasoning
000 WTPZ43 KNHC 081439 TCDEP3 Post-Tropical Cyclone Marie Discussion Number 30 NWS National Hurricane Center Miami FL EP132026 800 AM PDT Tue Sep 08 2026 Marie's satellite presentation has degraded since the previous advisory. Infrared satellite imagery depicts very weak remnant convection in the southeast quadrant, while visible imagery shows that Marie's low-level center is exposed. The latest subjective Dvorak estimate from TAFB classified Marie's intensity as 30 kt, while objective analysis from UW-CIMSS generally ranged from 25-36 kt. Given the most recent satellite trends, Marie's initial intensity has been lowered to 35 kt. The storm is now classified as a post-tropical cyclone due to a lack of deep convection. The initial motion was estimated at 300/8 kt. Marie is expected to turn more northwestward as it finds itself wedged between a cutoff low descending from the northeast Pacific and a high pressure system centered over the southwestern US. Little was changed to the most recent NHC track forecast, which reflects only a slight leftward shift to bring the official track slightly closer to HCCA. Marie is forecast to weaken and dissipate in the next couple of days as the system moves over progressively cooler SSTs and into a drier airmass. The latest intensity forecast moved up dissipation time slightly due to Marie's current rate of weakening following the latest model trends. This is the last advisory issued by the National Hurricane Center on this system.

Transit counts are gate-line crossings computed hourly from ChartNav's own live AIS network (terrestrial receivers; coverage varies by zone — the coverage figure above says how complete the picture is, and reporting gaps are only flagged for vessels that were underway and stopped reporting globally). Baselines are rolling medians of complete days. Numbers may differ from weekly satellite-AIS datasets such as IMF PortWatch, which lag by several days but see areas terrestrial receivers cannot.
