Post-Tropical Cyclone Theta Discussion Number  23

300 PM GMT Sun Nov 15 2020

Theta has run out of theta-e.  The cyclone has been without 
significant deep convection for many hours now and has been 
gradually spinning down today. It no longer meets the qualifications 
of a tropical cyclone, so this is the last advisory.  The initial 
wind speed is set to 25 kt per the latest scatterometer pass.  

The low is meandering this morning.  It is expected to be picked up 
to the north-northeast by the next trough over the northeastern 
Atlantic, along with an increase in forward speed.  The remnants of 
Theta should gradually lose strength due to strong shear, very dry 
air and little instability before dissipating in a day or two.
