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.
