Recon now reports pressure down to 916mb.
Also indicated is a concentric eyewall again.
Winds haven't increased.
What is the mean pressure (whatever the term is) for the NW Caribbean right now? The relative pressure is really what determines storm strength.
Edit: I just looked at the latest IR loop. Dean continues to amaze me, and I find it *extremely* difficult to believe - recon reports not withstanding - that there are no sustain winds within this monster that are > 170, let alone 150.
Edit2: Dean is now as strong as a Cat 4 'cane can be: "near 155mph" per the 8pm advisory.
Edit3: Pressure also down, to 915mb, according to the 8pm advisory.
It's almost guaranteed to be Cat 5 at 11pm, in my opinion.
