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. For additional information on the remnant low please
