Post-Tropical Cyclone Norbert Discussion Number  24
NWS Central Pacific Hurricane Center Honolulu HI   EP142026
Issued by NWS National Hurricane Center Miami FL
500 AM HST Tue Sep 15 2026

Norbert has lacked organized deep convection for about 18 hours 
now, and the only remaining thunderstorm activity is more than 120 
n mi from the center. Based on the persistent lack of organized 
convection, Norbert no longer qualifies as a tropical cyclone, and 
this is the last advisory on this system. The initial intensity is 
estimated to be around 30 kt.

The remnant low is moving westward at about 11 kt, and this general 
motion is expected to continue until the system opens into a trough 
on Wednesday.

For additional information on the remnant low please see High Seas
Forecasts issued by the National Weather Service, under AWIPS
header NFDHSFEPI, WMO header FZPN01 KWBC, and on the web at
