re: Hurricane Irma - Spinning Down

Tropical cyclones that form north of 15 degrees North and East of 35 degrees west do have a tendency to gain latitude and curve out to sea. What is interesting is that Irma is gaining strength quickly which would add to the Beta Effect and help it gain latitude.

Beyond 72 hours, I would not bet on any destination that this storm will take. Most models cannot handle upper level shortwaves and troughs accurately beyond 120 hours. Too many variables in play and the precision and timing of fronts and upper level features over the eastern pacific and north America cannot be accurately predicted at a 8-10 day forecast.
