we went through all this with irene. even in some of today's runs various globals aren't initializing it as anything, though it's a hurricane.
we've seen the nhc maintain classification systems like td 10 before. forecasters vary in how to classify such systems, i guess.
if you watch the cimss estimated shear, you'll notice that the shear zone is weakening and becoming less proximal to former 10. it's still too strong to allow the system to do more than minimal strengthening, but not what i'd consider strong enough to kill it. there is dry air infringement on the envelope of the low, but it isn't becoming more pronounced either. i'd put my money on its survival as of right now. all it has to do is keep bursting convection to do that.
