One of our own posted this in another thread:
I don't necessarily think it's a parasite, as you say. It appears like it could be an enhanced convergence boundary. ENE trades colliding with SW winds on the backside of Matthew creating lift in the form of this colossal feeder band.
And since the storm is not moving appreciably, and Matthew's circulation is not expanding, the feeder isn't moving either. Once he maneuvers himself out of the trade wind flow, that "parasite" is likely to either dissipate or assimilate into the storm.
Frankly, I think the added energy is giving him a much needed boost. TCHP cannot be very high where he is at the moment. I suspect there's some merit to the assumption that the added energy influx from the feeder is helping him sustain his small, yet-very-VERY-intense core. It's been ~24 hours with no EWRC, little dry air intrusion, and hardly any ill effects of shear in an environment that has to be exhibiting declining TCHP and SSTs.
THE QUESTION REMAINS: why are we seeing this anomaly NOW-- it sure hasn't shown up in
other hurricanes?
