Re: Tropical Storm Isaac Forecast Lounge

The key here seems to be that imminent 310-315 degree 'jog'
that the NHC put in about 36 hours ago.

And then it resumes it's 280-90 degree course.

And the NHC has just shifted that jog (lasting about 6 -8 hours at current speed) with each forecast.

Take out that 'jog' and Isaac misses Hispaniola and gets close to the EMCWF.

Question: What is going to cause that jog?
