Post-Tropical Cyclone Karina Discussion Number  43
NWS Central Pacific Hurricane Center Honolulu HI   EP112026
Issued by NWS National Hurricane Center Miami FL
500 PM HST Sun Sep 06 2026

Karina lost all of its organized deep convection late last night,
and it has been devoid of thunderstorm activity throughout the day.
Although a small patch of convection has formed about 90 n mi
northeast of the center, this area is quite limited and not well
organized. Therefore, Karina no longer meets the definition of a
tropical cyclone, and this is the last advisory on this system by
NHC. However, the cyclone is still producing gale-force winds north
of the center, and the initial wind speed is estimated to be around
40 kt based on earlier ASCAT data and the latest satellite intensity
estimates.
 
Strong shear, dry air, and cool waters should cause the
post-tropical cyclone to continue to weaken while it moves
west-northwestward in the low-level flow. All of the reliable
models show the low degenerating into a trough Monday night as
it approaches Hurricane Lowell to its west.
