When you have a 'cane of this intensity I'm wondering if Matthew is altering the environment around himself and pushing shear out of the intermediate area.

That's quite common with storms of the current category 4 strength, but at the start of the rapid intensification (just 24 hours ago) time period it was only a minimal 75mph category 1 hurricane.

We don't even need sub 900 to get a CAT five. Felix did it with a mid 930s  pressure in the same spot with a similar structure.

The hurricane has a very tight pressure gradient and higher mean background pressures than typical winds sampled for its central pressure. That actually has been the case since it closed off from an invest, hence why it went straight to a strong tropical storm on classification. The vortex has now been forced south of west against the ridge. Typically the easterly trade winds through the passage are higher. 930s likely would result in Cat 5 winds in the northern eyewall if Matt gets down that far tonight. Felix is a good example. Also, does anyone remember Dean?

930s won't take llong at this rate. Latest IR pic shows the RI is not letting up so there's a good chance the next Recon finds a pressure in the 930s on the first pass.

HOLY GUACAMOLE 

Recon just found 133 knots surface winds.
