Re: Irene Turning More Northwest Over the Bahamas

Pure northwest would be 315 degrees. The range for 'northwest' would be from 305 to 325 degrees. On the last bulletin, NHC stated a movement of 305 degrees, so by definition, that is a movement to the northwest. From 12Z to 18Z Irene moved 0.8 degrees north and 1.0 degrees west - or about 310 degrees - a northwesterly direction. Do hurricanes wobble along on their track - yes. However, the wobbles don't mean a thing in terms of defining direction until they become an established trend in a certain direction over something beyond a couple of hours of time.
