Hurricane Odalys Discussion Number  26
NWS National Hurricane Center Miami FL       EP162026
200 AM PDT Sat Sep 26 2026

Odalys continues to show signs of weakening. Satellite imagery shows 
the hurricane's eye has been obscured by a central dense overcast 
(CDO), though microwave imagery still indicates a well-defined 
low-level circulation center. A recent 0515 UTC Metop-C 
scatterometer pass revealed an asymmetric wind field. The latest 
subjective Dvorak CI number from TAFB was 5.5/102 kt, but the 
final-T number was 5.0/90 kt. This generally aligns with most 
UW-CIMSS objective satellite intensity estimates, which range from 
98 to 106 kt. Based on a blend of these data, the initial intensity 
is lowered to 100 kt.

The initial motion is estimated to be northward, or 355/4 kt, as the 
system continues to be steered by the flow between a mid- to 
upper-level trough to its west and a mid-level ridge over northern 
Mexico. The hurricane is forecast to continue on this trajectory 
over the next day or so as the aforementioned trough amplifies over 
the eastern Pacific. By early next week, Odalys is anticipated to 
abruptly turn to the east and southeast as the increasingly shallow 
circulation becomes steered by the low-level flow. The updated track 
forecast closely aligns with the reliable HCCA consensus aid, 
nudging slightly westward prior to the sharp easterly turn, and 
remains virtually unchanged from the previous advisory thereafter.
 
The latest SHIPS guidance depicts Odalys slowly moving into a more 
unfavorable environment, characterized by moderate to strong 
vertical wind shear, mid-level dry air, and cooler sea surface 
temperatures. These conditions will likely inhibit deep convection, 
making it difficult for Odalys to remain organized later this 
weekend. Consequently, the latest NHC forecast shows Odalys 
degenerating into a post-tropical cyclone by 60 h, a trend supported 
by simulated satellite imagery from both the GFS and ECMWF.
 
Distant moisture from Hurricane Odalys and Polo will be transported
into the southwestern United States this weekend and early next
week, and may indirectly contribute to a heavy rainfall and flash
flood threat in the region. See products issued by the Weather
Prediction Center for more information.
