Newest Dvorak still at T1.0/1.0. NHC addressed the differences in the forward speed of Harvey by the various models in the 5am disco.

"UNTIL ANOTHER APPROACHING TROUGH ACCELERATES THE WEST-SOUTHWESTERLY FLOW LATER IN THE PERIOD. THIS NEXT TROUGH...HOWEVER...WILL NOT HAVE MUCH AMPLITUDE SO IT SEEMS UNLIKELY TO BE ABLE TO CAUSE A BIG INCREASE IN HARVEY'S FORWARD SPEED. THE CONSENSUS OF THE TRACK GUIDANCE IS GENERALLY SLOWER THAN IN THE EARLIER RUNS...SO THE OFFICIAL FORECAST IS A LITTLE SLOWER THAN THE PREVIOUS ONE. THIS IS A COMPROMISE BETWEEN THE U.K. MET AND GFS...WHICH ARE SIGNIFICANTLY SLOWER THAN MY FORECAST...AND THE NOGAPS AND GFDL...WHICH ARE CONSIDERABLY FASTER."
