000 WTPZ43 KNHC 052040 TCDEP3 Hurricane Marie Discussion Number 19 NWS National Hurricane Center Miami FL EP132026 200 PM PDT Sat Sep 05 2026 Marie continues to exhibit a large ragged eye, around 60 n mi in diameter. Satellite estimates of the hurricane's intensity are very similar to what they were 6 hours ago, and therefore the initial intensity remains 80 kt for this advisory. The heading of the hurricane has been similarly steady, albeit at a slightly slower forward speed, with a motion estimate of 305/6 kt. Marie is moving along the western periphery of a ridge centered over the southern United States and will likely continue on a generally northwestward heading for most of the weekend. A short-term bend toward the west-northwest is still expected early next week as the cyclone weakens but it will ultimately accelerate northwestward as a mid- to upper-level trough digs quickly southward to the west of Marie by late Tuesday. A drier environment and cooler SSTs are still expected to cause Marie to slowly weaken during the next couple of days. The rate of weakening could increase after that as the environment gets more hostile and the aforementioned trough causes an increase in southerly wind shear across the cyclone. Marie is still expected to become a post-tropical remnant low near the 96 h mark, and could dissipate in about 5 days, though the forecast conservatively shows a point at that time for now. The NHC track and intensity forecasts are very close to the HCCA and GDM consensus aids.
