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.
