There has been no change in the steering pattern and Rita is moving westward or 275 degrees at 11 knots.
Problem is, for the last few frames (couple of hours) the motion has been NW, maybe WNW. It's turning sooner than expected, which could have major implications for eventual landfall (not to mention effects like higher tides) in areas further east than current "official" track would suggest. Just something to keep a very close eye on.
NHC uses a 6 hr mean motion. It is on or damn near the NHC forecasted track
I noticed that clearly as well in the satellite loop. Would guess it is just a wobble since the track maps are still converging.
