Post-Tropical Cyclone Katia Discussion Number  14
NWS National Hurricane Center Miami FL       AL122023
900 PM GMT Mon Sep 04 2023

The convection clock has run out on Katia with no organized
thunderstorm activity for most of the day.  No additional organized
convection is expected either due to very dry air aloft and
continued shear. Thus, the system is declared post-tropical, and
this is the last NHC advisory. The winds are set to 30 kt in
accordance with an earlier scatterometer pass.

Katia isn't moving much now, and it is forecast to drift in a small
clockwise loop over the next day or two within the subtropical
ridge.  The remnants of the system should move a bit faster
southward on Wednesday, gradually weakening due to the unfavorable
environment, and open up into a trough within 3 days.
